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.

fossile Dinosauria extinction mammifères
Un mammifère préhistorique récemment découvert pourrait détenir des indices sur la façon dont la vie a survécu à l’extinction des dinosaures. La minuscule espèce, Cimolodon desosai, vivait il y a 75 millions d'années et possédait des caractéristiques, comme un petit corps et un régime alimentaire varié, qui augmentaient probablement ses chances de survie. Trouvé en Basse-Californie, le fossile comprend de rares restes squelettiques qui révèlent comment il se déplaçait et vivait. Les chercheurs pensent que sa lignée a aidé les mammifères à endurer l’un des événements les plus meurtriers sur Terre.

os ADN fossile Dinosauria Tyrannosaurus
L’ADN des dinosaures est peut-être encore hors de portée, mais les scientifiques découvrent quelque chose de presque aussi passionnant : d’anciens vaisseaux sanguins cachés dans des os fossilisés. Dans un énorme Tyrannosaurus rex surnommé Scotty, les chercheurs ont découvert un réseau de vaisseaux préservés dans une côte qui s'était fracturée et avait commencé à guérir il y a 66 millions d'années. Grâce aux puissants rayons X synchrotron des accélérateurs de particules, ils ont pu observer l'intérieur du fossile dense sans l'endommager, révélant des structures complexes et riches en fer.

fossile formation
Sous le rift Turkana, en Afrique de l’Est, les scientifiques ont découvert que la croûte s’amincit jusqu’à atteindre un point critique, ce qui suggère que le continent se désagrège progressivement. Ce processus de « rétrécissement » marque un stade avancé de rifting qui pourrait éventuellement conduire à la formation d’un nouvel océan dans des millions d’années. Étonnamment, les mêmes forces géologiques qui divisent la terre peuvent également expliquer pourquoi la région détient un registre fossile si riche. Au lieu d'être le berceau de l'humanité, Turkana pourrait bien être simplement le lieu où
