Des empreintes de dinosaures vieilles de 150 millions d'années révèlent quelque chose d'étrange à propos de sa marche
locomotion pathologie empreintes Dinosauria
Un sentier spectaculaire vieux de 150 millions d'années et composé de plus de 130 empreintes de pas capture un sauropode géant effectuant une boucle complète avant de poursuivre son chemin. Sa foulée inégale laisse entendre que le dinosaure au long cou marchait peut-être en boitant.

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.

Un fossile de reptile vieux de 240 millions d'années révèle un chapitre perdu avant les dinosaures et les crocodiles
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.
