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.

Gandititan is a basal titanosaurian sauropod dinosaur from the Late Cretaceous of what is now China. It was a long-necked herbivore, typical of sauropods, with a relatively short tail, a characteristic of titanosaurs compared to other sauropods. Titanosauria have a wide range of body sizes, and Gandititan falls around the middle, slightly on the smaller side. Discovered with a fairly well articluated spine from neck to tail, Gandititan is estimated at about 14 m in total body length.

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.

Les scientifiques ont trouvé un bébé dinosaure caché dans la roche et il est étonnamment mignon
os dessin Corée du Sud Dinosauria Doolysaurus tomographie découverte crâne
Des scientifiques ont découvert un bébé dinosaure rare en Corée du Sud et l'ont baptisé Doolysaurus, en hommage à un célèbre personnage de dessin animé. Grâce à des tomodensitogrammes de pointe, ils ont découvert des os cachés, notamment un crâne, dans la roche beaucoup plus rapidement que les méthodes traditionnelles. Le jeune dinosaure, peut-être duveteux et ressemblant à un agneau, avait même des calculs gastriques révélant qu'il mangeait un mélange de plantes et de petits animaux. Cette découverte suggère que de nombreux autres dinosaures pourraient encore être cachés dans les roches coréennes.

os Dinosauria
Certains sauropodes plus petits pouvaient se tenir debout sur leurs pattes postérieures avec une facilité surprenante, leur donnant accès à une nourriture plus riche et un avantage défensif. Des simulations informatiques montrent que leurs os supportent mieux le stress que ceux de leurs parents plus grands. Cependant, à mesure qu’ils grandissaient, le poids rendait cette posture beaucoup plus difficile à maintenir. Ce qui a commencé comme une astuce utile dans la jeunesse est devenu une démarche stratégique plus limitée à l’âge adulte.

Des scientifiques ont recréé un nid de dinosaure pour résoudre un mystère vieux de 70 millions d'années
nid Dinosauria Oviraptor oiseau
Les scientifiques ont recréé un nid d'oviraptors grandeur nature pour comprendre comment ces dinosaures ont fait éclore leurs œufs. Leurs expériences ont montré que le parent ne pouvait probablement pas chauffer tous les œufs directement, ce qui signifie que la lumière du soleil jouait un rôle clé. Ce chauffage inégal pourrait faire éclore les œufs d’un même nid à des moments différents. Les résultats suggèrent que les oviraptors utilisaient une méthode d’incubation hybride contrairement aux oiseaux modernes.

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.
