Crâne de mosasaure d'espèce Platecarpus tympaniticus (squamates, mosasaures).
Provenance : Smoky Hill Chalk, Kansas (aux Etats-Unis).
Date : Crétacé supérieur, période du Campanien, 88 millions d'années avant notre ère.
Collections du Muséum national d'histoire naturelle de Paris (France).
Exposé à l'occasion de l'exposition "Un T-Rex à Paris" au Muséum national d'histoire naturelle de Paris (France) du 6 juin au 2 septembre 2018.

Légende du fossile dans cette exposition : "Les mosasaures ne sont pas des dinosaures mais des reptiles marins, très répandus à la fin du Crétacé. Certains genres comme Globidens et Halisaurus sont connus aussi bien aux Etats-Unis qu'au Maroc. Ces animaux étaient d'excellents nageurs, capables de traverser l'Atlantique."

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.

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

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.

Pendant des décennies, Paranthropus Robustus a intrigué les scientifiques en tant que cousin puissant et à grande mâchoire des premiers humains. Aujourd’hui, grâce à d’anciennes analyses de protéines, les chercheurs ont découvert de nouveaux secrets cachés dans l’émail dentaire vieux de 2 millions d’années. Ces protéines ont révélé à la fois le sexe et des différences génétiques subtiles entre les fossiles, suggérant que Paranthropus n'était peut-être pas une seule espèce mais un mélange évolutif plus complexe.

migration Indonésie fossile découverte évolution
Une découverte révolutionnaire sur l'île indonésienne de Sulawesi révèle que les premiers hominidés ont traversé des mers dangereuses il y a plus d'un million d'années, laissant derrière eux des outils en pierre qui remodèlent notre compréhension des migrations anciennes. Ces découvertes, plus anciennes que les preuves précédentes dans la région, mettent en évidence Sulawesi comme une pièce essentielle du puzzle de l’évolution humaine. Pourtant, l’absence de fossiles maintient l’identité de ces fabricants d’outils entourée de mystère, suscitant de nouvelles questions quant à savoir s’ils étaient des Homo avant.
