Pampadromaeus

Cabreira et al. 2011

Pampadromaeus est un genre fossile de dinosaures sauropodomorphes basaux du Trias supérieur. Il a été décrit en 2011 à partir de restes fossiles découverts dans l'état de Rio Grande do Sul, au Brésil. Ce genre ne comporte qu'une seule espèce, Pampadromaeus barberenai, décrite par Sérgio Cabreira (d) et son équipe en 2011.

(A) A phylogenetic principal-component analysis (PCA) represents the projection of the Dinosauria supertree (STAR Methods) into a PCA of climatic variables. PC1 axis shows strong positive correlation with maximum temperature ([temp max), low positive correlation with precipitation seasonality ( precip season), strong negative correlation with minimum temperature (Ytemp min), and strong negative correlation with minimum precipitation (Yprecip min). PC2 axis shows strong positive correlation with minimum temperature ([temp min) and negative correlation with precipitation seasonality (Yprecip season). Shadows around points highlight the relative density in the principal compo- nent space of non-dinosaurian Dinosauromorpha (gray), Ornithischia (blue), Sauropodomorpha (green), and Theropoda (red). (B) Lower left plot shows 95% confidence interval convex hulls for each dinosauromorph subclade. Blue thermometer (top left corner) symbolizes the direction of the vector in the PC space region for cold temper- atures; yellow thermometer (top right corner) indicates the direction of the vector in PC space for warm tem- peratures; brown shrub (top right corner) depicts dry conditions, while the same with a gray, rainy cloud (mid, lower side of the graph) illustrates seasonal conditions. Silhouettes represent the following taxa (clockwise from the higher left corner): Minmi, Edmontosaurus, Pachyrhinosaurus, Tyrannosaurus, Asilisaurus, Graci- liceratops, Harpymimus, Altirhinus, Gobititan, Suz- housaurus, Marasuchus, Pampadromaeus, Herrer- asaurus, Vulcanodon, Diplodocus, Giraffatitan, Coelophysis, Dromomeron, Gondwanatitan, Tapuiasaurus, Anchisaurus, Siamotyrannus, Diodorus, Suchomimus, Phuwiangosaurus, Ouranosaurus, Irritator, Tangvayosaurus, Nanshiungosaurus, Aeolosaurus, Rebbachisaurus, Chuxiongosaurus, Tethyshadros, Koreanosaurus. Genyodectes, Mapusaurus, Vegavis, Goyocephale, and Rhoetosaurus. © Alfio Alessandro Chiarenza, Juan L. Cantalapiedra, Lewis A. Jones, Paul J.
