Dinosauria Goyocephalia
Qunkasaura is a titanosaurian sauropod dinosaur that lived approximately 75 million years ago in the Late Cretaceous of what is now Spain. Specifically, it is a saltasaurid titanosaur, and its discovery marks the first instance of two distinct lineages of this group present in the same locality. In the Late Cretaceous, Europe was a large archipelago, and the coexistence of these differing lineages indicates that saltasaurids arrived in the Iberian Peninsula much later than other groups of dinosaurs.

Jiangxititan a titanosaurian sauropod from the Late Cretaceous of China. Typical for a sauropod, it had a long neck and stood on four pillar-like legs to support its massive body. Jiangxititan is a member of the Lognkosauria, which include some of the largest dinosaurs known, and is one of the few from mainland Asia. The discovery of Jiangxititan demonstrates the presence of both early-diverging and late-diverging titanosauriform sauropods in that area during the Late Cretaceous.

Ces dinosaures avaient des ailes mais ne pouvaient pas voler
plume fossile Anchiornis Dinosauria oiseau
Certains dinosaures à plumes ont peut-être brièvement pris leur envol, pour y renoncer plus tard. En étudiant des fossiles rares avec des plumes préservées, les chercheurs ont découvert un indice surprenant caché dans les schémas de mue, révélant qu’Anchiornis ne pouvait probablement pas voler du tout. Au lieu du remplacement soigné et symétrique des plumes observé chez les oiseaux volants, ces dinosaures ont présenté une mue désordonnée et irrégulière, ce que seuls les animaux incapables de voler présentent.

Un squelette de dinosaure presque complet découvert en Patagonie aide les scientifiques à percer le mystère des alvarezsaures, un groupe étrange de dinosaures ressemblant à des oiseaux. Le fossile d'Alnashetri cerropoliciensis révèle que ces animaux sont devenus minuscules avant de développer leurs caractéristiques spécialisées ultérieures, telles que des bras tronqués et des adaptations mangeuses de fourmis. Pesant moins de deux livres, le dinosaure est l’un des plus petits connus d’Amérique du Sud.

Les scientifiques ont comparé les dinosaures aux mammifères pendant des décennies, mais n'ont pas compris cette différence clé
prédateur juvénile Dinosauria mammifères
Les bébés dinosaures n’étaient pas dorlotés comme des lionceaux ou des éléphanteaux, ils ressemblaient plutôt à des enfants préhistoriques à clé. De nouvelles recherches suggèrent que les jeunes dinosaures se sont rapidement isolés, formant des groupes réservés aux enfants et survivant sans grande aide parentale, tandis que leurs grands parents menaient des vies complètement différentes. Étant donné que les juvéniles et les adultes mangeaient des aliments différents, affrontaient différents prédateurs et se déplaçaient dans différentes parties du paysage, ils pourraient avoir fonctionné presque comme des espèces distinctes.
