Il a fallu 40 ans au T. rex pour atteindre sa taille réelle, selon une étude
os croissance prédateur spécimen Tyrannosaurus étude
Le Tyrannosaurus rex a peut-être mis beaucoup plus de temps à grandir que les scientifiques ne le pensaient autrefois. En analysant les anneaux de croissance des os fossilisés des pattes de 17 spécimens de tyrannosaures et en utilisant de nouvelles méthodes statistiques, les chercheurs ont découvert que le célèbre prédateur avait probablement mis environ 40 ans pour atteindre sa taille maximale, soit environ huit tonnes, au lieu des 25 ans précédemment estimés.

crête Crétacé Crétacé supérieur spécimen Canardia Dinosauria Parasaurolophus
Cette semaine, nous allons nous intéresser à un dinosaure à bec de canard très populaire.  Dites bonjour à Parasaurolophus !  Le parasaurolophus était un herbivore qui vivait dans ce qui est aujourd'hui l'Amérique du Nord à la fin du Crétacé, il y a environ 77 à 73 millions d'années.  Le parasaurolophus mesurait environ 9,1 mètres de long du bec à la queue, mais certains spécimens incomplets montrent qu'ils étaient un peu plus grands.  Parasaurolophus est surtout connu pour sa longue crête incurvée qui s'est développée à l'arrière de sa tête, givi

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.
