Reconstruction of Tuebingosaurus maierfritzorum gen. et sp. nov. as a quadruped dinosaur, using the outline of Riojasaurus as a base ‒ next to the silhouette of Friedrich von Huene. The drawing of the bones is based on and modified from the original illustrations of specimen “GPIT IV” in von Huene (1932, pl. 38) that have been replicated in the literature. The right fibula is marked in grey as it was found nearby with similar measurements to the left fibula and has been assumed to be part of the same individual.

Reconstructed skull of Jaxartosaurus aralensis Riabinin, 1937. Only a posterior portion of the skull, as well as a surangular is known, with the rest of the skull being based mostly upon File:Aralosaurus skull.png. Jaxartosaurus is currently classified as a basal lambeosaurine, more derived than Aralosaurini, but more primitive than Parasaurolophini and Lambeosaurini. It might be more derived than Tsintaosaurini (Godefroit et al., 2004). References:

Why Were There No Tiny Non-Avian Dinosaurs? Mammals May Have Been to Blame
Pourquoi n’y avait-il pas de petits dinosaures non aviaires ? Les mammifères pourraient être à blâmer
écologie prédateur reproduction Dinosauria évolution mammifères
Les dinosaures ont évolué pour devenir certains des plus grands animaux ayant jamais foulé la Terre, mais un nouveau modèle mathématique suggère que les premiers mammifères les auraient chassés des niches écologiques réservées aux plus petites créatures. Cet article, intitulé « Pourquoi n'y avait-il pas de minuscules dinosaures non aviens ? Les mammifères en seraient-ils responsables ? », a été initialement publié sur Sci.News: Breaking Science News.

prédateur Brésil Trias fossile Dinosauria évolution autres reptiles
Un reptile vieux de 240 millions d'années découvert au Brésil révèle à quoi ressemblait l'évolution juste avant l'avènement des dinosaures et des crocodiles. Le petit prédateur avait des pattes inhabituellement positionnées qui lui permettaient peut-être de se déplacer plus efficacement que de nombreux reptiles antérieurs. Ses proches parents étaient auparavant connus principalement sur d’autres continents, ce qui suggère que ces animaux anciens se sont répandus beaucoup plus loin dans le monde du Trias que les scientifiques ne le pensaient.

Les dinosaures sont devenus des géants – alors pourquoi ne sont-ils jamais devenus minuscules ?
écologie croissance Dinosauria évolution mammifères
Les dinosaures ont conquis la terre à des tailles énormes, mais étrangement, ils n'ont presque jamais évolué pour devenir de véritables animaux minuscules. De nouvelles recherches suggèrent que la physiologie à elle seule ne peut pas expliquer cette extrémité miniature manquante du spectre des dinosaures et que les premiers mammifères pourraient en être en partie responsables. Alors que les dinosaures empêchaient les mammifères de devenir grands, les petits mammifères pourraient leur rendre la pareille en occupant des niches écologiques qui auraient autrement pu accueillir des dinosaures de la taille d'une souris.
