A restoration of Rinconsaurus compared to a human ,

•  Based proportionally on fossil elements and skeletal reconstruction featured in the Rinconsaurus description,[1] with missing parts based on other titanosaur reconstructions. The remains of Rinconsaurus represent two adults and a juvenile all of which are incomplete; some of the proportions shown here, such as the neck, limb lengths, and skull shape are not certain.
•  Osteroderms are not yet known in Rinconsaurus.  The osteoderms shown here are based loosely on Mendozasaurus.[2] Osteoderms are known from at least 10 titanosaur genera spread across the family tree but it's not clear if all titanosaurs had them.[3] Titanosaur osteoderms are rare and their layout and position on the body are not certain. [4]
•  The colours and patterns, as with the majority of reconstructions of prehistoric creatures, are speculative.
•  Human silhouette approximately 180 cm tall.

Mounted replica of a composite skeleton of Edmontosaurus annectens on display at the University of Oxford Museum, Oxford, England. The original skeleton is compiled from disarticulated fossil bones from a bonebed of the Hell Creek Formation, exposed in the Ruth Mason Quarry in Harding County, South Dakota. It is 8.5 m (28 ft.) long and the skull is almost 1 m (39 in.) in length.[1][2]

De nouveaux fossiles au Qatar révèlent une petite vache marine cachée depuis 21 millions d'années
os Qatar fossile
Des fossiles du Qatar ont révélé une petite espèce de vache marine nouvellement identifiée qui vivait dans le golfe Persique il y a plus de 20 millions d'années. Le site contient la collection la plus dense connue d’os fossiles de vaches marines, démontrant que ces animaux prospéraient autrefois dans de riches prairies d’herbiers marins. Leur rôle écologique reflète celui des dugongs modernes, qui remodèlent encore les fonds marins du Golfe en broutant. Les résultats pourraient aider les chercheurs à comprendre comment les écosystèmes d’herbiers marins réagissent aux changements environnementaux à long terme.

Des analyses du cerveau fossile montrent que les ptérosaures ont évolué en un éclair
vol fossile Pterosauria oiseau découverte évolution
Les anciens ptérosaures ont peut-être pris leur envol bien plus tôt et de manière plus explosive que les oiseaux, développant le vol dès leur origine malgré leur cerveau relativement petit. Grâce à l'imagerie CT avancée, les scientifiques ont reconstruit les cavités cérébrales de fossiles de ptérosaures et de leurs proches parents, découvrant des indices surprenants, tels que des lobes optiques élargis, qui suggèrent un saut rapide vers le vol motorisé. Leurs découvertes contrastent fortement avec l'évolution lente et par étapes observée chez les oiseaux, dont le cerveau s'est développé au fil du temps.

Cet os rare résout enfin le mystère du Nanotyrannus
os croissance musée fossile spécimen Nanotyrannus Tyrannosaurus découverte
Les scientifiques ont confirmé que Nanotyrannus était une espèce mature et non un jeune T. rex. Un examen microscopique de son os hyoïde a fourni la preuve clé, correspondant aux signaux de croissance observés dans les spécimens connus de T. rex. Cette découverte suggère un écosystème de tyrannosaures plus riche et plus compétitif qu’on ne le pensait auparavant. Il montre également comment les fossiles de musée et les analyses de pointe peuvent réécrire l’histoire préhistorique.

Un parent de crocodile nouvellement identifié en Égypte repousse les origines des dyrosauridés chasseurs marins de plusieurs millions d'années. Le fossile, Wadisuchus kassabi, présente un mélange de traits primitifs et avancés qui marquent une transition évolutive clé. Des spécimens rares d’âges différents révèlent comment ces anciens prédateurs se sont développés. Cette découverte renforce l’Afrique en tant que centre de l’évolution précoce des dyrosauridés.

membre dent prédateur fossile évolution nouvelle espèce crâne
Un minuscule fossile du Devon vieux de 242 millions d’années bouleverse les hypothèses des scientifiques sur les premiers membres de la lignée des lézards. Au lieu des charnières du crâne et des dents du palais typiques des lézards et des serpents modernes, cette ancienne créature présente un mélange surprenant de traits primitifs et inhabituels, ainsi que des dents étonnamment grandes en forme de lame. Les scans synchrotron haute résolution ont révélé des détails invisibles à l'œil nu, aidant ainsi les chercheurs à nommer la nouvelle espèce Agriodontosaurus helsbypetrae
