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]

Un fossile d'ambre vieux de 16 millions d'années vient de révéler la plus petite fourmi prédatrice jamais trouvée
prédateur fossile évolution extinction
Une fourmi fossilisée des Caraïbes, Basiceros enana, conservée dans de l'ambre dominicain, révèle l'ancienne aire de répartition de l'espèce et renverse les hypothèses sur l'évolution de sa taille. L’imagerie avancée montre qu’il possédait déjà les adaptations de camouflage de ses parents modernes, offrant de nouvelles perspectives sur les stratégies d’extinction et de survie.

Un poisson vieux de 400 millions d'années révèle une grave erreur dans notre compréhension de l'évolution
fossile découverte évolution
Un poisson considéré comme la capsule temporelle de l’évolution vient de surprendre les scientifiques. Une dissection détaillée du cœlacanthe – une espèce vieille de 400 millions d’années souvent appelée « fossile vivant » – a révélé que les muscles clés censés faire partie de l’évolution précoce des vertébrés étaient en réalité des ligaments mal identifiés. Cela signifie que les hypothèses fondamentales sur la façon dont les vertébrés, y compris les humains, ont évolué pour manger et respirer, devront peut-être être réécrites. La découverte corrige des décennies d'erreurs anatomiques et remodèle l'histoire de s

Un fossile vieux de 500 millions d’années vient de réécrire l’histoire de l’araignée
fossile
Il y a un demi-milliard d’années, une étrange créature marine appelée Mollisonia symetrica aurait ouvert la voie aux araignées modernes. Grâce à une analyse détaillée du cerveau des fossiles, les chercheurs ont découvert des schémas neuronaux étonnamment similaires à ceux des arachnides d'aujourd'hui, ce qui suggère que les araignées ont évolué dans l'océan et non sur terre comme on le pensait auparavant. Cette structure cérébrale fait même allusion à un saut évolutif critique qui a permis aux araignées d’acquérir leur fameuse vitesse, leur dextérité et leurs prouesses à tisser des toiles. Les résultats constituent un défi de longue date
