Nambashag Worthy 2011, GEN. NOV.
No full textNAMBASHAG GEN. NOV. Type species: Nambashag billerooensis sp. nov. Diagnosis: A phalacrocoracid diagnosed by the following unique combination of characters: ulna with proc. cotyla dorsalis not distinctly hooked distally; coracoid with cotyla scapularis having a shallow sulcus; femur with insertion for M. caudofemoralis a short ovate crista immediately proximal to the nutrient foramen well separated from the crista marking the insertion of M. flexor ischiofemoralis more proximally; tibiotarsus with the thickened tip of the crista cnemialis cranialis in line with rest of the crista, rather than offset anteriorly, sulcus extensorius laterally placed, and pons supratendineus proximodistally short; tarsometatarsus with tendinal canal for M. flexor hallicus longus open plantarly, the tendinal canal for M. flexor digitorum longus nearly enclosed, the tendinal canal for M. flexor perforatus digiti 2 broadly open laterally, groove for M. extensor hallicus longus where it passes over the dorsomedial shaft margin significantly wider than shaft width, lateral margin slightly concave in anterior view, sulcus for M. abductor digiti IV deep over whole length of shaft so crista plantaris dorsalis is parallel and close to the dorsal facies over whole shaft length, and foramen vasculare distale relatively small and well separated from incisura intertrochlearis lateralis. Etymology: Noun in the nominative singular, masculine; from Namba, from which formation most fossils herein derive, and shaahg, the European name for Phalacrocorax aristotelis, from Old Norse skegg (the beard), so called on account of the recurved crest of feathers that its head is adorned with in spring plumage. The name ‘shag’ first appeared in Merrett (1667).Published as part of Worthy, Trevor H., 2011, Descriptions and phylogenetic relationships of a new genus and two new species of Oligo-Miocene cormorants (Aves: Phalacrocoracidae) from Australia, pp. 277-314 in Zoological Journal of the Linnean Society 163 (1) on page 284, DOI: 10.1111/j.1096-3642.2011.00693.x, http://zenodo.org/record/544075
Phalacrocoracidae REICHENBACH 1849
No full textFAMILY PHALACROCORACIDAE REICHENBACH, 1849: SHAGS AND CORMORANTS <p> The following fossil taxa are referred to Phalacrocoracidae rather than other pelecaniform families (Pelecanidae, Fregatidae, Sulidae, Anhingidae) by the following unique combination of characters: (1) humerus with a deep, rather than shallow, fossa pneumotricipitalis ventralis; (2) humeral proc. flexorius with equal or greater prominence than the epicondylus ventralis, not less; (3) humeral proc. supracondylaris dorsalis located distal to the proximal margin of the condylus dorsalis (exception: <i>Nambashag microglaucus</i> gen. et sp. nov. is primitive for this character); (4) ulna with the tuber. collateralis ventralis elongate and distinctly separated from the cotylar margin; (5) carpometacarpus with the ventral rim of the trochlea carpalis ventralis joining the shaft markedly distal to the proc. pisiformis; (6) coracoid with the protuberant boss on the cranial margin of the facies artic. sternalis dorsalis occupying no more than half the total width of the articular facet; and (7) femur with the tuber. gastrocnemialis lateralis elongate and distinctly separated from the trochlea fibularis. Phalacrocoracids are also diagnosed by the following additional characters that were not assessable in the fossil material at hand: premaxillae with rostral grooves extending to near the tip, os lacrimales fused to the os frontales, large fonticuli cranioorbitales in the caudal walls of the orbits, and os palatines only partly or not fused medially.</p>Published as part of <i>Worthy, Trevor H., 2011, Descriptions and phylogenetic relationships of a new genus and two new species of Oligo-Miocene cormorants (Aves: Phalacrocoracidae) from Australia, pp. 277-314 in Zoological Journal of the Linnean Society 163 (1)</i> on page 283, DOI: 10.1111/j.1096-3642.2011.00693.x, <a href="http://zenodo.org/record/5440759">http://zenodo.org/record/5440759</a>

Australlus Worthy 2011, new genus
No full textGenus Australlus new genus Type species. Gallinula disneyi Boles, 2005. Etymology. From australis, Latin, southern, and as it relates to Australia; and rallus, Latin, name of rails. Diagnosis. Differs from other genera of the Rallidae by the following unique combination of characters. Humerus with 1), crus dorsale fossae very robust; 2), tuber. ventrale relatively robust and dorsoventrally wide, with an autapomorphic arrangement of the similar sized insertion scars for the three ligaments arranged in an equilateral triangle, with that for the lig. m. coracobrachialis caudalis largest, ovate and occupying the caudal tip of the tuberculum, the scar for lig. m. subscapularis on the dorsal facies distinctly cranial to that for the lig. m. coracobrachialis caudalis and the scar for the lig. m. subcoracoideus on the ventral facies level with, but slightly cranial to, the scar for lig. m. coracobrachialis caudalis and only slightly smaller; 3), tuber. supracondylare ventrale relatively small and not extending proximally as far as condylus dorsalis; 4) and proc. flexorius projecting greatly ventrally. Coracoid, 5), with a prominent crista procoracoidei extending from the proc. procoracoideus to close to the crista medialis. Tarsometatarsus, 6), elongate, about 1.5 times the femoral length; 7), with crista medialis hypotarsi elongate, extending more than half the length of the hypotarsus; and 8), enclosing two hypotarsal canals, one for the tendon for M. flexor digitorum longus (canal 1) and the more plantar one (canal 2) that carried the two tendons, M. flexor perforatus digiti II and M. flexor perforans et perforatus digiti II. Stratigraphy and age. All specimens of Australlus disneyi derive from sites of Faunal Zone A and B, except QM F20799 from Ringtail Site, which is attributed to Faunal Zone C (Travouillon et al., 2006), and therefore is presumed to be of Middle Miocene age. QM F20799 does not differ materially from the other specimens of A. disneyi and is of similar size (Boles, 2005a), so there is no reason to doubt its identity. However, its preservation is unlike the other two specimens from Ringtail and similar to specimens from White Hunter Site, so perhaps its site of origin is incorrectly recorded.Published as part of Worthy, Trevor H., 2011, Australlus, a New Genus for Gallinula disneyi (Aves: Rallidae) and a Description of a New Species from Oligo-Miocene Deposits at Riversleigh, Northwestern Queensland, Australia, pp. 61-77 in Records of the Australian Museum 63 (1) on page 64, DOI: 10.3853/j.0067-1975.63.2011.1563, http://zenodo.org/record/467665
