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] ↑ Dinosaurs in the Museum.

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 ancien crocodile égyptien au long museau réécrit l’évolution
chasse prédateur Égypte fossile spécimen découverte évolution
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.

Un mini-prédateur vieux de 242 millions d'années change l'évolution du lézard
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

Les scientifiques découvrent un lien surprenant entre le plomb et l’évolution humaine
dent fossile évolution génétique
Les chercheurs ont découvert que les anciens hominidés, y compris les premiers humains, étaient exposés au plomb tout au long de leur enfance, laissant des traces chimiques dans les dents fossiles. Des expériences suggèrent que cette exposition pourrait avoir entraîné des changements génétiques renforçant les fonctions cérébrales liées au langage chez les humains modernes.
