Jinchuanloong is a relatively basal sauropod that measured an estimated 10 m in length. Sauropod skulls typically don't preserve well in the fossil record, but Jinchuanloong is known mainly from the skull, and parts of the neck and tail. Like all sauropods, Jinchuanloong was a quadrupedal herbivore that used its long neck to reach the vegetation that it fed on.

Cet ancien parent du crocodile a grandi sur quatre pattes puis a marché sur deux
fossile Dinosauria
Un étrange parent d'un crocodile de l'époque des dinosaures réécrit ce que les scientifiques pensaient savoir sur les anciens reptiles. Cette créature de la taille d'un caniche, appelée Sonselasuchus cedrus, semble avoir commencé sa vie en marchant à quatre pattes avant de passer à une position sur deux pattes à mesure qu'elle grandissait - une transformation inhabituelle rarement observée dans les archives fossiles.

Canada fossile spécimen nouvelle espèce
Les paléontologues ont identifié un nouveau genre et une nouvelle espèce de polype médusozoaire tubicole au corps mou à partir de spécimens bien conservés trouvés à environ 50 km au nord-est de la ville de Québec au Canada. L'article Des fossiles vieux de 450 millions d'années révèlent un étrange parent de méduses tubicoles apparaît en premier sur Sci.News : Breaking Science News.

Ces minuscules fossiles de dinosaures ont trompé les scientifiques pendant 20 ans
armure os croissance fossile Ankylosauria Dinosauria découverte
De minuscules fossiles de dinosaures qui ont intrigué les scientifiques pendant plus de 20 ans ont enfin révélé leur véritable identité. Plutôt que d’appartenir à une espèce miniature, ce sont en réalité des bébés ankylosaures, certains âgés de moins d’un an, y compris un possible nouveau-né. En étudiant les schémas de croissance osseuse, les chercheurs ont confirmé que ces jeunes dinosaures n’étaient pas encore devenus des adultes de grande taille. La découverte apporte un nouvel éclairage sur la façon dont les ankylosaures se sont développés, montrant qu'ils ont commencé à développer une armure étonnamment tôt.

Les scientifiques pensaient qu'il s'agissait d'un jeune T. rex. Ils avaient tort
os croissance prédateur fossile juvénile Dinosauria Nanotyrannus
Un mystère de longue date sur les dinosaures pourrait enfin être résolu : Nanotyrannus, autrefois considéré comme un simple T. rex adolescent, semble avoir été une espèce distincte après tout. Les scientifiques ont analysé un minuscule os de la gorge du fossile original et ont découvert des schémas de croissance montrant que l'animal était déjà mature et non un géant juvénile en devenir. Ce petit prédateur, environ la moitié de la taille d'un T. rex adulte, errait probablement aux côtés de son célèbre cousin, ajoutant une nouvelle couche de complexité à l'écosystème préhistorique.
