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
Ricardo N. Martínez
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.
