Reconstruction of the terrestrial paleoenvironmental setting of the Sao Khua Formation by Renata Cunha.
In the center, a generalized spinosaurid feeds on a sauropod. This trophic relationship is hypothesized based on isolated tooth crowns found in association with a sauropod skeleton [67]. In the background, a small pack of the ornithomimosaur theropod Kinnareemimus. Both sauropods and ornithomimosaurs (as part of the “herbivorous” theropods) were found to be positively associated with terrestrial paleoenvironments by Butler and Barrett [15].

Ce « crocodile terroriste » de 31 pieds mangeait des dinosaures. Maintenant c'est de retour
prédateur musée États-Unis Dinosauria squelette
Un énorme « crocodile terroriste » de la taille d’un bus qui s’attaquait autrefois aux dinosaures a été ramené à la vie avec des détails époustouflants grâce au premier squelette complet scientifiquement précis de Deinosuchus schwimmeri. S'étendant sur plus de 9 mètres de long, cet ancien prédateur suprême régnait sur le sud-est des États-Unis il y a plus de 75 millions d'années. Les visiteurs peuvent désormais le voir de près au Tellus Science Museum, le seul endroit au monde à posséder cette réplique.

fossile Alnashetri Alvarezsauria Dinosauria oiseau évolution squelette
Un squelette de dinosaure presque complet découvert en Patagonie aide les scientifiques à percer le mystère des alvarezsaures, un groupe étrange de dinosaures ressemblant à des oiseaux. Le fossile d'Alnashetri cerropoliciensis révèle que ces animaux sont devenus minuscules avant de développer leurs caractéristiques spécialisées ultérieures, telles que des bras tronqués et des adaptations mangeuses de fourmis. Pesant moins de deux livres, le dinosaure est l’un des plus petits connus d’Amérique du Sud.

Royaume-Uni Jurassique fossile Ichthyosauria évolution squelette
Un ichtyosaure nouvellement identifié de la côte jurassique du Royaume-Uni est en train de réécrire une partie du manuel préhistorique. Surnommé le « dragon-épée du Dorset », ce reptile marin de trois mètres de long a vécu pendant une période d’évolution mal comprise, au cours de laquelle les principaux groupes d’ichtyosaures disparaissaient et de nouveaux apparaissaient. Son squelette magnifiquement préservé – doté d’un museau en forme de lame et d’un éventuel dernier repas – permet de déterminer le moment où cette transition dramatique s’est produite.

Cette semaine, nous allons découvrir un parent de crocodiliens modernes qui a trompé les scientifiques à plusieurs reprises !  Entrez Hesperosuchus agilis ! Hesperosuchus était un pseudosuchien (lié aux crocodiliens) qui vivait dans ce qui est aujourd'hui l'Arizona et le Nouveau-Mexique, aux États-Unis, à la fin du Trias, il y a environ 210 millions d'années.  Il s'agissait probablement d'un mangeur de viande et, du museau à la queue, le squelette le plus complet mesure environ 1,2 m (4 pieds), mais d'autres fossiles suggèrent qu'il aurait pu devenir plus grand, jusqu'à environ 1,2 m.

Colombie évolution squelette
Un squelette colombien vieux de 5 500 ans a révélé le plus ancien génome connu de la bactérie liée à la syphilis et aux maladies associées. L’ancienne souche ne rentre pas parfaitement dans les catégories modernes, faisant allusion à une forme oubliée qui s’est divisée au début de l’évolution de l’agent pathogène. Cela repousse l’histoire des maladies tréponémiques dans les Amériques de plusieurs millénaires et montre qu’elles se diversifiaient déjà bien avant les documents écrits.
