JVP 29(1) chock full o' dinosaurs (Spoiler Alert)



In what's shaping up to be a banner week, there's no less than nine articles on non-avian dinosaurs in the new issue of JVP, plus plesiosaurs, birds, and even a stray pterosaur paper. Regrettably, I don't have time to key in the citations (much less the abstracts), but there's at least one new dinosaurian taxon, the Argentinean sauropodomorph Adeopapposaurus mognai. (That's Latin for "far eating lizard," on account of the long neck.) Looked like such a fun name to type, I just had to give it a try!

(Oh, alright, I'll type that one in...)

ADEOPAPPOSAURUS MOGNAI, GEN. ET SP. NOV. (DINOSAURIA: SAUROPODOMORPHA), WITH COMMENTS ON ADAPTATIONS OF BASAL SAUROPODOMORPHA
pp. 142-164

Abstract - Prosauropods are basal sauropodomorphs that were the major terrestrial faunal components from the Norian until their extinction during the Toarcian. Their status as a natural group is debatable. In the present work I describe Adeopapposaurus mognai, a new sauropodomorph from the Cañón del Colorado Formation, in northwestern Argentina. Diagnostic autapomorphies and combination of characters of Adeopapposaurus include a series of large foramina in a sub-vertical row on the lateral surface of the premaxilla; strongly rugose depression bordered by a protuberance with a series of foramina in a sub-vertical row, on the lateral surface of the interior end of the dentary; eleven anteroposteriorly elongated cervical vertebrae and thirteen dorsal vertebrae with neural arches taller than the respective centra. Phylogenetically Adeopapposaurus is resolved as the sister group to Massospondylus; differing from the latter based on differences in mandible and premaxilla and addition of one dorsal vertebra to the neck. The specimens described here reveal numerous herbivorous adapatations, including the presence of a highly vascularized bony plate in the premaxilla and dentary, which indicates that it had a horny beak.
