Data from: Puercosuchus traverorum n. gen. and sp.: a new malerisaurine azendohsaurid (Archosauromorpha: Allokotosauria) from two monodominant bonebeds in the Chinle Formation (Upper Triassic, Norian) of Arizona
<p><span><span>Non-archosaur archosauromorphs are a paraphyletic group of diapsid reptiles that are important members of global Middle Triassic and Late Triassic continental ecosystems. Included in this group are the azendohsaurids, a clade of allokotosaurians (kuehneosaurids and Azendohsauridae + Trilophosauridae) that retain the plesiomorphic archosauromorph postcranial body plan but have evolved disparate cranial features that converge on later dinosaurian anatomy, including sauropodomorph-like marginal dentition and ceratopsian-like postorbital horns. Here we describe a new malerisaurine azendohsaurid from two monodominant bonebeds in the Blue Mesa Member, Chinle Formation (Late Triassic, ~218</span><span>–</span><span>220 Ma); the first occurs at Petrified Forest National Park and preserves a minimum of eight individuals of varying sizes, and the second occurs near St. Johns, Arizona. <em>Puercosuchus traverorum</em> n. gen. and sp. is a carnivorous malerisaurine that is closely related to <em>Malerisaurus robinsonae</em> from the Maleri Formation of India and to <em>Malerisaurus langstoni</em> from the Dockum Group of western Texas. Dentigerous elements from <em>Puercosuchus traverorum</em> confirm that some Late Triassic tooth morphotypes thought to represent early dinosaurs cannot be differentiated from, and likely pertain to, <em>Puercosuchus</em>-like malerisaurine taxa. These bonebeds from northern Arizona support the hypothesis that non-archosauriform archosauromorphs were locally diverse near the middle of the Norian and experienced an extinction event prior to the end-Triassic mass extinction coincidental with the Adamanian-Revueltian boundary recognized at Petrified Forest National Park. The relatively late age of this early-diverging taxon (Norian) suggests that the diversity of azendohsaurids is underrepresented in the Middle Triassic and Late Triassic fossil records around the world.</span></span></p>

The ontogenetic pattern of neurocentral suture closure in the axial skeleton of Hyperodapedontinae (Archosauromorpha: Rhynchosauria) and its evolutionary implication
<p>Understanding ontogeny of a taxon is a crucial step to properly elucidate its taxonomy and evolution. However, aside from histological data, osteological criteria for assessing maturity are considered lineage specific or controversial. The sequence of neurocentral suture closure of the axial skeleton of extant crocodilians, which occurs in a postero-anterior sequence, has being used as a non-destructive method to determine maturity in extinct reptiles. However, the use of this criterion in extinct archosaurs not closely related to crocodilians is debatable, as the ancestral condition of Archosauria is unknown and variation occurs in timing and sequence orientation within the clade. We have assessed the pattern of neurocentral suture closure of the Hyperodapedontinae rhynchosaurs, an early archosauromorph clade distantly related to archosaurs. Different from extant crocodilians, they exhibit an antero-posterior sequence neurocentral suture closure. Relative size and other ontogenetic markers suggest the neurocentral closure in the Hyperodapedontinae is correlated to aging, although closed sutures were rare in the sample. A high number of open or partially open sutures in mature individuals indicate that they remained open during most of their life. Our study indicates that (i) the delayed neurocentral closure can be a paedomorphic heterochronic process in Hyperodapedontinae, as it contrasts with the fully closed neurocentral sutures of early diverging non-hyperodapedontine rhynchosaurs; (ii) the assumption opened neurocentral sutures indicates immaturity in extinct reptiles is not always correct; and (iii) the delayed closure may have originated independently in several archosauromorph lineages, but the ancestral condition of Archosauria likely follows the crocodilian closure pattern.</p>
