A hypothetical life restoration of Ampelosaurus atacis

• Ampelosaurus is known from hundreds of fossil specimens which show most of the dinosaur's osteological details, however, there are few articulated remains or reconstructions of the material so its overall proportions and life appearance are uncertain.
• Ampelosaurus is known to have supported osteoderms, only four are currently known. The number of these osteoderms that an individual Ampelosaurus would have supported in life and their and position on the body is not currently known. It's thought that due to the rarity of titanosaur osteoderms that they would be quite sparse on the body. The position and layout of the osteoderms has been loosely based on this interpretation, which is based on the work of Vidal et al 2015. [1]

Ce dinosaure de 2 livres réécrit ce que les scientifiques savent de l'évolution
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.

Des fossiles perdus révèlent des monstres marins qui ont pris le relais après la plus grande extinction de la Terre
prédateur Australie Madagascar fossile extinction
Une cache perdue de fossiles vieux de 250 millions d’années en Australie a réécrit une partie de l’histoire de la vie après la pire extinction massive de la Terre. Au lieu d’une seule espèce d’amphibien marin, les chercheurs ont découvert des preuves d’une communauté étonnamment diversifiée de premiers prédateurs océaniques. L'une de ces créatures avait des parents s'étendant de l'Arctique à Madagascar, ce qui montre que certains des premiers tétrapodes marins se sont répandus à travers le monde à une vitesse remarquable.

Un fossile de « Sword Dragon » vieux de 190 millions d’années réécrit l’histoire des ichtyosaures
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.

Un spinosaure géant à crête, le « héron de l'enfer », découvert dans le Sahara
crête prédateur Niger fossile Dinosauria Spinosauria
Au cœur du Sahara, des scientifiques ont découvert Spinosaurus mirabilis, un nouveau prédateur spectaculaire couronné d'une crête massive en forme de cimeterre qui aurait pu autrefois briller de couleurs sous le soleil du désert. Découvert dans des gisements de rivières intérieures isolées au Niger, le fossile réécrit ce que nous pensions savoir sur les dinosaures spinosaures, suggérant qu'ils n'étaient pas des chasseurs entièrement aquatiques mais de puissants échassiers traquant les poissons dans les cours d'eau boisés à des centaines de kilomètres de la mer.

Le tricératops avait un nez géant qui aurait pu refroidir sa tête massive
fossile Triceratops tomographie crâne
La tête massive du tricératops faisait peut-être plus que simplement montrer ces fameuses cornes. À l’aide de tomodensitogrammes et de reconstructions 3D de crânes fossiles, les chercheurs ont découvert un système nasal étonnamment complexe caché à l’intérieur de son énorme museau. Au lieu d’être simplement un nez surdimensionné pour sentir, il abritait probablement des réseaux complexes de nerfs et de vaisseaux sanguins, et même des structures spéciales qui aidaient à réguler la chaleur et l’humidité.
