Boreodon matutinus Lambe 1902
No full textBoreodon matutinus. Sp. nov. Plate XV., fig. 15. This early type of mammal is represented by a single tooth, a premolar, having two, slightly divergent roots. The crown is in the form of a laterally compressed cone, somewhat rounded above, angular in front, evenly rounded behind, with a well defined, undulating cingulum encircling its base. A slight lateral concavity, more clearly defined within, occurs in each side of the tooth near the base of the crown in line with the cleft between the roots. The cingulum is angular and pl'ominent at either end, becoming rounded and broader on the sides. The crown is considerably worn on the inner side of its apex. One root only remains and it is imperfect below.Published as part of Lambe L.

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. For the purpose of comparison a reduced figure OI-this ilnmense bone is given with a‘ similarly reduced drawing Of. the femur of Iguanodon mantelli, Uwen, from the Wealden of Filgate Forest, Sussex, England (/ see fig. 21). *Amen Joiir. Sci. and Arts. vol. XLIII, pl. 111, fig. 4. 1892 . . Fig. 22, illustrates,. in a diagrammatic manner, the general mode of succession of teeth in the genus Trachodon. The teeth are represented as they appear in transverse sections of the jaws, the heavy lines indicating the keeled enamelled crowns of the teeth. Thus although. in both _ the upper and lower jaws the teeth replace each other from the inner side, yet the enanielled surface ofthe CIOWH Of the teeth are on the inner side in the lower jaw but on the outer side in the maxilla. With this species is connected the name of Dr. Alfred R. Ü. Selwyn, C. M. G., for many years, prior to 1894, Director of the Geological Survey.Published as part of Lambe L.

Ptilodus primaevus Lambe 1902
No full text<p>Ptilodus primaevus. Sp. nov.</p> <p>Plate XV, figs. 13 and 14.</p> <p>I`he speeimen on which this species is based consists of an imperfect right mandibular ramus in which the fourth premolar and the first molar are preserved. The fracture in front exposes the large anterior root of the premolar and the small posterior root is seen from the outer side. The lower front border of the crown ofthe premolar is slightly excavated apparently for the accommodation of the posterior edge of a very small, closely fitting third premolar. The socket for the base of the root of the incisor is seen 011 the inner side and indicates a tooth of comparatively robust proportions. Behind the first molar, the socket of the second molar is preserved, which, judging from its size, held a tooth considerably smaller than the first molar.</p> <p>The characters of the teeth are as follows: —Fourth premolar with eleven serrations on its edge; on its inner side, five complete grooves preceded by three half grooves; on its outer side, five complete grooves preceded by one half groove. First molar with four tubercles on its inner side and six tubercles on the outer side.</p> <p>Ptilodus primaevus is especially interesting on account of the small number of grooves on the large cutting fourth premolar (approching the genus Meníscoëssus ill this respect) and the slightly backward curve of the tubercles on the outer side of the first molar, also suggestive of Meníscoëssus.</p> <p>In the figures of the type of the species, the teeth are shown as they appear in the specimen, but the first molar is evidently somewhat out of its true position of close proximity to the fourth premolar.</p> <p>Belly River series, Red Deer river, 1901.</p>Published as part of <i>Lambe L.

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. Middle and upper beds of the Dinosaur Park Formation, Alberta, Canada (Ryan & Evans 2005). Referred specimens. CMN 2245; AMNH 5402; ROM 843; YPM 2016; NHMUK R 4948 (after Ryan & Evans 2005). The NHMUK specimen is referred to Chasmosaurus because it possesses characters 1, 3, 4 and 5 from the diagnosis of Chasmosaurus (above); it is referred to C. belli because it possesses character 1 from the diagnosis of C. belli (above). Specimens removed from C. belli. ROM 839 was referred to C. belli by Ryan and Evans (2005) and Longrich (2010), but is not diagnosable to species level based on the amended diagnosis presented here and represents Chasmosaurus sp.Published as part of Maidment, Susannah C.

Stegoceras validus Lambe 1902
No full text<p>Stegoceras validus. Sp. nov.</p> <p>Plate XXI, figs. 1 - 5.</p> <p>The two s mmetrical, com act bones 7 re P resented on plate XXI I were found se mratel. The lower portions of their sides, as well as their ends, consist of sutural surfaces, indicating that other bones were firmly united to them and completely surrounded them. A transverse suture divides each almost equally into an anterior and a posterior half. On the lower surface there is evidence of a line of coalescence in a longitudinal direction and extending from end to end. The upper surface of each specimen is dome shaped. In the larger specimen the anterior end is produced forward and is slightly elevated terminating in two projections; the surface is here distinctly nodose. In the lateral, posterior, upper surface a similar rugosity is apparent. The surface of the central convexity is smooth.</p> <p>In the smaller specimen the upper surface is smooth and pittcd throughout. It is trilobed posteriorly and is not produced forward in front where, however, two small nodes occur, one on each side of the median lino.</p> <p>The structure of the lower surface is marked by a number of smooth, concave areas, as represented in the reproductions, from photographs of the specimens, in figs. 2 and 5 of plate XXI.</p> <p>It is probable that these bones were situated in the median lino of the head, in advance of the nasals. They may have belonged to a species of dinosaur not otherwise represented in the collections from Red Deer river and, judging from the difference in shape ofthe two specimens, more than one species may be indicated. Marsh in his figurc ofthe head of Triceratops serratzós* shows a nasal horn core (divided both transversely and longitudinally by sutures) that may correspond to the specimens from Red Deer river.</p> <p>A third specimen, similar to the anterior half of the larger of the two bones was collected in 1901. It has separated from its posterior half along the lino of the transverse suture.</p> <p>For these bones the name Stegoceras validas is proposed with the hope that future discoveries may aid in a clearer understanding of their aflinities.</p> <p>Belly River series, Red Deer river. 1898, 1901.</p>Published as part of <i>Lambe L.
