Malefica is a hadrosaurid dinosaur from the Late Cretaceous of Texas in the United States. Like other hadrosaurs, Malefica was herbivorous, processing plant matter with their broad beaks and battery of teeth in the back of the mouth. It could grow to around 6 m in length, and weighed about 1 t. The discovery of Malefica helped to understand the distribution of hadrosaurs in Cretaceous North America, as well as evolutionary lineages between basal hadrosaurs and the more derived saurolophids.

Dzharacursor is an ornithomimid theropod dinosaur from the Late Cretaceous of what is now Uzbekistan. Ornithomimids like Dzharacursor are known for their long legs lending to a cursorial, or running, lifestyle. They had a feathered covering, and were likely omnivorous, or possibly herbivorous. Adult Dzharacursor could grow to approximately 3.5 m in length.

Ahvaytum is a saturnaliid sauropodomorph from the Late Triassic of what is now Wyoming. It is the oldest known dinosaur from the northern continent of Laurasia, challenging previous hypotheses of dinosaur origins and dispersal. Typical of basal dinosaurs from the Triassic, Ahvaytum was a small slender biped, reaching about 1 m in body length.

Huashanosaurus is a basal sauropod dinosaur that lived from the Early to Middle Jurassic periods of what is now China. It was a long-necked herbivore which still exhibited many basal traits of the earlier sauropodomorphs, while transitioning to obligate quardupedality. Huashanosaurus grew to approximately 12 m in length, and weighed around 10 t.

Fujianvenator is an anchiornithid avialan from the Late Jurassic of China, whose discovery gave important insight to the evolution of birds. It had proportionately long legs, with the tibia twice the length of the femur. This suggests it may have been a strong runner, and possibly had a terrestrial or wading lifestyle. Fujianvenator was a small dinosaur, weighing about 640 g. As an avialan, it was almost certainly covered in feathers, though it does not seem likely to have been capable of flight.

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.

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.

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.
