Trachodon selwyni Lambe 1902
No full textTrachodon (Pteropelyx) selwyni. Sp. nov. Plate III, figs. 2 and 3. This species is established principally on the evidence of teeth, of which a number from the lower jaw are shown on plate III. The teeth follow each other, quincuncially in the usual Trachodont manner, three or four occurring in the vertical series, but seven or eight can be counted obliquely. They replace each other from the inside and appear in the grinding surface in two or three functional rows. When three teeth belonging to the same vertical row are in use in the grinding surface at the same time (see fig. 3 of plate III), the outer one is generally worn down to the root and the stump is ready to fall out, the middle one is about half Worn down, whilst the inner one is either just coming into use or is only slightly worn. The teeth of this species differ from those of T. mirabilis, Leidy, in being rounded oval above, instead of terminating in a point. They are smooth in both species. A few minute, obliquely transverse strize are observed on the inargins of the teeth of T selwyni but they are practically smooth, the marginal, oi' border sculpture chariicíerislie of the teeth of the species described in the next following pages being absent A few, very large mandibular rami without teeth, one of which is represented in fig. 24, A, are supposed to belong to this species. A femur, provisionally associated with T selwyni, was secured during the summer of 1901. It measured about 1 ' 425 M. (56 inches) in length When perfect. It is.585 M. and.508 M. * in circum- feience above and blow the third trochanter respectively, and indicates 1 the size attained by some of the herbivorous dinosaurs during Mid-Cretaceous times.

Taxon displaying the combination of characters unique to the genus Chasmosaurus along with the following features: (1) parietal posterior bar bearing no median emargination and is nearly straight so that it forms a ‘T’ shape with the parietal median bar; (2) lateral pair of epiparietals large and triangular; others, when preserved, are smaller (after Godfrey & Holmes 1995). Both characters are autapomorphic for C. belli within Chasmosaurus. Holotype. CMN 491, a partial parietal. Although fragmentary, the holotype is diagnostic based on the combination of generic character 4, and specific character 1, a combination not observed in any other chasmosaurine. Distribution.

Gorgosaurus libratus Lambe 1914
No full textGorgosaurus libratus Lambe 1914: This taxon is known from more numerous and more complete specimens than any other North American species of tyrannosaurid. The ontogeny of this species includes many parts of the growth series (Carr 1999).It is presently only confirmed from the Late Campanian Dinosaur Park Formation of Alberta: as the isolated postcranial material from other formations referred to this taxon do not show features unique to Gorgosaurus libratus, these assignments are tentative at best. A large but incomplete tyrannosaurid skull from the Judith River, FMNH PR308, has formed the basis of many restorations of Gorgosaurus libratus (Russell 1970, fig. 1; Paul 1988, 335; Carpenter 1992,frgs.1,2E), but lacks Gorgosaurus synapomorphies and in fact almost certainly represents a specimen of Daspletosaurus torosus (Carr1999).Published as part of Holtz, T.

Stereocephalus tutus Lambe 1902
No full textStereocephalus tutus. Sp. nov. Plate XI, plate XII, figs. 1, 2, 3, 4 and 5, and plate XXI, figs. 6, 7 and 8. The speeimen of Which views from above, from the side and from below are given on plates XI and XII, represents part of the plate-protected cranium of a herbivorous dinosaur, that is, apparently, quite distinct from any hitherto described. With the head was found a transverse series of coössified sharply keeled scutes which will be described farther on. The part of the head preserved is strongly convex transversely, but only moderately so from front to back. Goôssified plates cover the whole of the upper surface and are continued down on the vertical sides. They are arranged with a certain amount of bilateral symmetry, are quite small at the centre and toward the back, but are larger in front and very much more so on the sides. They are for the most part irregularly five or six sided, with rather undulatory surfaces that are marked by an irregular, raised, structural cross-hatching, feebly suggestive of the surface markings of the plates of Nodosaurus textilis, Marsh. Small vascular openings and grooves are also numerous on the surface. The edges of the plates are as a rule angular and sometimes raised. Each plate has its limit defined by a deep circumscribing furrow, so that although they are coôssified and form a continuous surface covering to the head, they do not lose their individuality. A rounded node, or an incipient keel is noticed on some of the plates. The removal of sandstone from the lower surface of the specimen revealed the bones of the palatal region (plate XII. fig. 2). The interpretation of these elements are as indicated by the letters. The back ends, only, of the palatines (P) are seen, meeting the pterygoids in a suture indicated at “ s. From here the latter bones (pt.) extend backward on either side of interpterygoid vacuities (v.). The ridge (pb.) represents the presphenoid and basisphenoid elements; it is bent posteriorly to one side in the specimen, which has been subjected to considerable pressure from above and is somewhat crushed behind. From this intel'pretation of the bones of the palate it would appear that the part of the armature preserved covers the upper part of the head near the union of the nasals With the frontals. No indication of the 01'bits can be detected and it is probable that they were placed far forward in the head. Part of a rib, having a T-shaped transverse section (Plate XII, fig. 5), such as is characteristic of the heavily armoured Slegosauría, was found separately but in the same locality, and is provisionally associated with S. tutus. The finding of such a rib is sufficient evidence of itself to prove the existence, during the time of the deposition ofthe Belly River series, of a large dinosaur having a heavy protective covering of bony plates [table omitted] With the 11ead,just described, Were five keeled, bony scutes or plates that have since been found to fit together in the form of an arch (plate XII, figs. 3 and 4), Whose sides curve forward as well as (lownward. This oblique curve places the lower, paired scutes, as seen when the arch is viewed from above, a little in advance of the upper pair which is again slightly in advance of the median plate The scutes rest on and are ossified to a thickness of bone that constitutes the inner, continuous surface of the arch. This band of bone, ornamented above by paired ossicles, suggests the possibility of its being the back border of the posterior crest of the species to which the head armature, above mentioned, belonged. This suggestion is given credence from the fact that the concave edge of the band of bone on which the scutes rest is fractured, whilst the convex edge appears to be intact. Numbering the ossicles from the right, the junction between Nos. 1 and 2 was perfect, as were also those between Nos. 3, 4 and 5, but iii the case of Nos. 2 and 3 the fractured edges did not fit with sufiicient exactness to remove all doubt as to their being placed side by side, although the continuity and symmetry of the curve of the under surface seemed complete. It is possible that one or two scutes are missing froın between Nos. 2 and 3, especially as fragments of similarly shaped scutes were found at the same spot. If an additional soute completed the series it probably would have been the mate of the present median one, or if two were required to fill the gap (if such a gap exists) one would be on the median line, the other would correspond with No. 3 to form another pair. The addition of one or two scutes to the series would result only in extending and possibly flattening the curve. The median sente is apparently symmetrical, the others are asymmetrical, forming pairs with reversed lateral proportions. The scutes have an irregularly oval basal outline, are sharply keeled, with sloping sides shallowly excavated from the keel downward but convexly curved from front to back, their basal edges are defined by an engirdling furrow below which, at a lower level, they are laterally expanded to meet each other in a plane surface. A very small ossicle rises above this intermediate basal surface between Nos. 3 and 4. Vascular markings are conspicuous on the sides of the scutes. From the appearance of the outer, basal edges of scutes Nos. 1 and 5, it seems probable that these scutes constituted the lateral terminations of the series. [table omitted] Belly River series, Red Deer river, 1897. The tooth shown in fig. 12, is of the Stegosaurían type. It differs from those, of the Red Deer river district, referred to the two species of Palœoscincus, and is about twice as large as those of P. costatus. 1 t is figured here with the idea that it may eventually prove to belong to S. tutus. It was collected below Berry creek, on Red Deer river, in 1901. A spinous dermal plate of massive proportions, fig. 13, A and B, is referred to this species on account of its similarity, in structure and surface markings, to the postcranial keeled scutes described above. This specimen was collected in 1897. Another large plate similar in general proportions to the above and nearly as large, as Well as numerous others of different sizes and of a variety of shapes, were collected in 1901.Published as part of Lambe L.

Trachodon marginatus Lambe 1902
No full textTrachodon (Pteropelyx) marginatus. Sp. nov. Plate III, fig. 1, plate IV, figs. 1, 5 and 6, and plates V, VI, VII, VIII, IX and X. Excellently preserved remains, of a large herbivorous dinosaur, met with in abun- dance in the Red Deer river district, arc referred to the above species. Although the various bones of the skeleton were generally found distributed, a number Were discovered associated with each other, the remains of one individual. These consisted of the hunie- Tus, ulna and radius of the left fore limb, a metatarsal and phalanges of the pes, the zygapophyses of cervical vertebrtc, ribs, fragments of teeth, broken ossilied tendons and impressions of the integument. The species is represented further by disassociated femora, tibize, inetacarpals and phalanges of the manus, rami ofthe lower jaw and maxillte with remarkably well preserved teeth in place, dorsal and caudal vertebrtc, a pubic bone, ischia, ilia, chevron bones and numerous teeth as Well as other remains probably referable te the same species. Of the bones, of one individual, found in association, the humerus with the ulna and radius are figured on plates VI and VII. The humerus, figs. 1 and 2, has a prominent radial crest that extends, from the external tuberosity above to slightly more than half way down the shaft externally and is roughly striated at its lower end ior the attachment of the deltoid muscle. The head is small and is supported below by a strong rounded ridge. The proximal end, seen from above, is roughly triangular in shape, the front face broadly excavated with conspicuously concave surfaces on either side of the head behind that continue forward to meet the inner and outer‘ tuberosities. The condyles are separated by a deep depression behind, that extends up the shaft for a short distance; in front they are not so conspicuously divided. An archaic feature is expressed in the great downward extension and conspicuous singularity of the radial crest. In comparing this humerus with that of Hadrosaurus Foulkii, * Leidy, from the Cretaceous of the east, a form allied to this species, a marked difference is noticeable in their proportions. [table omitted] * 1 SG5. Cretaceous Reptiles of the United States, p. 7 G, pl. xiv, figs. 1, ‘l, 3 and 4. Smithsonian Contr. to Knowledge, vol. xiv. The ulna and radius, belonging to the same fore limb as the humerus, are figured as they Were found, The ulna has a strongly developed olecranon process terminating its expanded proximal end which is concave on three sides so as to be subtriangular in section. From the middle ofits shaft downward, it increases in size very little. The radius is a comparatively slender" bone but terminates below in a carpal articu- lating surface slightly larger than that of the distal end of the ulna. [table omitted] The right femur, plate VIII, provisionally associated with T marginatus, is interesting in many particulars, notably, its slenderness, the prominence of the head, the backward extension of the condyles and the marked development of the third trochanter. The inner condyle is larger than the outer one,‘ they are both, viewed from the side, broadly rounded posteriorly and pointed in front. From the great trochanter, a prominent ridge extends dowrrward, for some distance on the outer front face of the bone. [table omitted] A comparison of this femur with that of Hadrosaurus foulkii, Leidy reveals a great similarity in their general proportions. If anything, the Red Deer‘ river‘ specimen is more slender but otherwise there are no very marked differences. The tibia (plate IX, figs. 1 and 2), Was probably not as long as the femur‘ but was a decidedly robust bone. Unfortunately no specimens were secured associated With femora that might be supposed to belong' to the same individual. Of the two right tibiae figured on plate IX (provisionally referred to T. rnarginatus), the one on the right, seen fr‘orn behind, is considerably crushed so as to exaggerate the breadth of the proximal end; the other specimen is remarkably Well preserved. This bone of the leg, cylindrical at mid-length, expands rapidly toward either‘ end. The longer axis of the distal end is nearly at right angles to that of the proximal end. Viewed from behind, the proximal end is seen to be broadly concave, the outer‘ side consisting of a backwardly directed flange. On the inner side the head is divided into two parts by a deep furrow. [table omitted] Ramus of lower jaw, plates III and IV, long and narrow, with teeth occupying a deep, narrow chamber or magazine in the posteriortwo-thirds of the length. Cororroid process high, rising abruptly from the outer‘ side, of the posterior end; laterally compressed above, deeply excavated below posteriorly. An edentulous prolongation in front curves obliquely downward and inward with a symphyseal surface at the: inner forward end. Upper and lower borders nearly parallel. Outer wall of dental chamber thick and strong, with shallow, vertical, alveolar‘ grooves occupying its inner side. Inner‘ wall,.very thin, averaging about 2 mrn. in thickness, Without alveolar‘ grooves proper; seldom preserved. Coronoid process below, produced backward externally as a thin plate of bone continuous With the outer surface of the jaw; on its inner‘ side it unites with the outer‘ alveolar‘ wall in advance of the posterior end of the dental chamber. Derrtary canal leading from the upper‘ part of the posterior cavity forward between the outer‘ surface of the jaw and the dental chamber‘. Mandibular groove passing forward under the lower‘ border‘ of the chamber‘. A row of foramina occurs on the inner side, one foramen at the base of each vertical series of teeth. A number of foramina also present on the outer‘ suface. Teeth replaced from within, their keeled, erranrelled surfaces of the crown inside occurring in a vertical series of three or four near the middle of the jaw with two or three ofa series in use in the grinding surface at the same time. Their lateral margins decorated with small, rounded projections fr‘om near the apex downward to where the crown begins to narrow again. [table omitted] [table omitted] Maxilla, plate V, robust, high at the centre, sloping downward toward either end, the dental chamber occupying nearly the whole of its length. Seen from above, the posterior half slopes obliquely forward and outward, while the reverse is the case in front; at the extreme anterior end there is a limited slope inclined obliquely outward. Also, viewed irom above, the posterior half is straight and broader than the front half which narrows to a- rounded, outwardly turned point. Inner surface rather flat. Outer surface with a rounded ridge running horizontally from the posterior end to meet the facet for the articulation of the anterior end of the jugal. On the inner, upper side behind mid-length, a facet, probably for the palatine, is present. Teeth replacing each other from the inner side, apparently not more than two, of a series in v;se in the grinding surface at the same time; the carinated, enamelled faces of the crowns facing outward. A row of foramina, similar to that of the lower jaw, conspicious in the upper part of the inner side. Several large foramina occur in the anterior half of the outer side. [table omitted] Pubis, plate X, fig. 1 (provisionally associated with T.marginatus), produced forward into a broad, thin, transversely compressed, spatulate expansion that is slightly concave on its outer surface. Posteriorly a slender postpubic process, springing from a point inside and in advance of the base of the pedestal bearing the ischiac facet, is directed backward on the lower border of the ischium with which it effects a ligamental union. Iliac facet small, separated from the isehiac facet by a wide, concave, acetabular emargination that forms about one-third of the whole acetabular‘ border. [table omitted] Isehium long, plate X, fig. 2 (provisionally associated with T. marginatus), laterally compressed, broadly expanded proximally and ending distally in a loot-shaped extremity pointing downward. Shaft almost straight, its upper‘ edge curving concavely and broadly upward to meet the iliac facet Upper expanded part very thin, plate-like, thickened abruptly, on either side of the thin, concave edge of the acetabular border, to form well developed iliac and pubic facets. The surfaces of the facets very rugose. A narrow postpubic facet extends, downward and backward at right angles to the pubic facet along the lower front border of the proximal end. Below this facet and separated from it by a concavity in the thin margin is a flange of bone for the further support of the postpubis. Inner surface of distal half, striated longitudinally for a ligamental union with its mate of the opposite side. [table omitted] A number of ilia, representing difierent types of herbivorous dinosaurs, are included in the collections. In fig. 23, three of these are shown. The upper one, A, is of the Monoclonius type and is arbitrarily associated with. dawsoni. another, B, is referred to Trachodon marginatus (provisionally), Whilst the lower one; C, Stegosauroid in its character, may belong to Stereocepltalus tutus.Published as part of Lambe L.

Ornithomimus altus Lambe 1902
No full textOrnithomimus altus. Sp. nov. Plates XIII and XIV, and plate XV, figs. 1 -8. A hitherto undescribed species of dinosaur, belonging to the Omilhumimidœ and referable to the genus Ornithomimus of Marsh, is represented by a complete right hind limb (including the foot), the phalanges of the left foot in place, a pubic bone, and an ischium, of individual. \Vith these, as probably belonging to the same species, are included a posterior dorsal vertebra, caudal vertebrae of remarkable form, phalanges of the manus and a number of teeth of peculiar shape. The femur, tibia, metatarsals and phalanges of the pes, except the terminal ones. are hollow. The femur is shorter than the tibia. The astragalus is closely applied to but does not coalesce with the distal end of the tibia; it has a well developed ascending process apposed to the front face of the tibia. The fibula is slender and the tibia has a prominent cnemial crest. The calcaneum and the tarsal bones were found in place. Metatarsal III, as in Ornithomimus velox * Marsh, fits closely against metatarsals II and IV, and is, a short distance above its distal end, triangular in section with its flat face foremost. It becomes attenuated above and passes behind the other two metatarsals. Metatarsal V, represented by a short, laterally compressed, slightly curved boııe, lies close to the proximal end of metatarsal IV. The phalangeal formula is 3, 4, 5; digit III is the longest and digits II and IV are of about equal length. The terminal phalanges are sharply pointed in front, rather straight, flattened below and deeply grooved on the sides. The grooves are carried forward to the extreme point and indicate the presence, during life, of a long but not sharply curved or pointed claw. The other phalanges have deep pits, one on each side of their distal extremities. The shape of the terminal phalanges suggests afoot, not suitable for grasping but adapted rather for speed in running, an idea carried out by the slenderness and lightness of all the bones of the leg. The posterior dorsal vertebra, plate XIV, fig. 1, is decidedly amphicœlous, the concavity in the anterior face of the centrum being more marked than in the posterior one. The centrum is constricted at mid-length só as to have concave sides and lower surface, there being at either end of the latter a broad median groove. The neural arch does not reach far below the top of the centrum. The diapophyses (imperfect in the specimen) have stout bases, relatively broad in their antero-posterior diameters. The faces of the prezygapophyses are directed obliquely inward. The neural spine is well developed, short, deep from back to front, shallowly concave on its sides, with rugose, slightly excavated, anterior and posterior surfaces. The centrum is hollow, its walls dense and about 2 ' 5 mm. thick at mid-length, the inner space extending to within about 6 mm. of either end. ’Sixteenth Annual Report, U. S. Geol. 1896 Iviii Survey,, plate., fig. 2. The caudal vertebrae, plate XIV., figs. 2-—5, and plate XV., figs. 1—5, supposed to belong to this species, are remarkable for the suppression of the neural spine and the forward horizontal extension of the prezygapophyses to a distance in advance of the anterior end of the centrum nearly equal to the length of the centrum itself. The postzygapophyses are represented by a backwal‘dly directed, laterally compressed, nearly horizontal process that fitted between the prolonged prezygapophysial processes of the succeeding vertebra. The centrum is long‘ compared with its height, slightly concave on its sides and lower surface, with a strong median groove below. In different specimens its interior may be moderately hollow or instead a number of Vacuities of variable size may be present. Small facets, for the attachment of the chevron bones, are present at the lower, posterior ends of the centra; these are not recognized at the anterior ends. The neural spine is sometimes represented by a narrow, rounded ridge (shown at “ w ” in the specimen figured on plate XV., fig. 2). The prezygapophysiatl processes are broadly expanded laterally, contracting and thinning gradually anteriorly, their outer edges overhanging the sides of the anterior end of the centrum and extending lower than the median upper surface of the same; their lower surfaces are slightly striated longitutlinally. The neural canal is small, its outlet, anteriorly, is wider than high and is roofed over to a point above the anterior end of_ the centrum. These caudal vertebrae indicate a tail of considerable length but their manner of articulation would scarcely admit of much lateral motion. A number of phalanges of the supposed manus of this species are also hollow but present a difference in the shape of the terminal phalangcs which are curved and laterally compressed with a groove on e-ach side extending‘ from the apex backward and dividing into two branches toward the proximal end. Judging from the size of these phalanges the manus was smaller than the pes, and their shape suggests a grasping capacity; the terminal phalanges were probably encased in sharp, hooked claws giving their possessor the power of tearing its prey. Two bones, probably the distal ends of the first metatarsalif and the first metacarpal, were found with, the phalanges of the manus above referred to, phalanges of the pes, a separate astragalus and a ealc-aneum.

[table omitted] The tooth represented in figs. 12 and 13 ofplate XIV is provisionally associated With this species and is regarded as being from the anterior portion of the jaw. A similar tooth, figured by Leidy, in his memoir on the Judith river vertebrata (Trans. Amer. Philos. Soc. 1859) is referred to in his description of the teeth of Deinodon horridus as an aber- rantly formed specimen. Leidy suspected the tooth to be an incisor. In the tooth figured on plate XIV, one only of the posterior keels is denticulated and that only for a short distance at the centre of its length; the other is smooth. Another specimen is apparently Without denticulations. A number of teeth of this shape, With others intermediate iii form between them and the orthodox Megalosauroid tooth, Were collected in the Red Deer river district. They are referred to the present species on account of their frequent occurrence With and near the remalns of O. altus. The estimated length of Ornithomimus altus is 22 feet.

O FOTÓGRAFO NO JARDIM DO CIDADÃO: MEMÓRIA DE UM LAMBE-LAMBE
No full text This article proposes possible inflections for the senses that photographs made of the city and in the city acquire with the passing of time and it relates some of these inflections with the permanence of personages whose function and activity do not justify anymore in the universe of contemporary photographic making. The reflection is established on the trajectory of the „lambe-lambe‟ Edgar Borges that has been working as a photographer for almost forty years at Coronel Pedro Osório Square in the city of Pelotas, Rio Grande do Sul. The Edgar's work is emphasized as a popular craft, a street work, besides standing out the techniques and the photographic language used by the photographer throughout his trajectory. It is observed, as an aspect of the same importance the presence of the wooden ponies as a scenic element used by the photographer to cdefine his work in the interior of the square. Finally, such inflections contribute for discussions about photography and memory.

Por fim, tais inflexões contribuem para as discussões sobre fotografia e memória
