Reconstructed skull of Jaxartosaurus aralensis Riabinin, 1937. Only a posterior portion of the skull, as well as a surangular is known, with the rest of the skull being based mostly upon File:Aralosaurus skull.png. Jaxartosaurus is currently classified as a basal lambeosaurine, more derived than Aralosaurini, but more primitive than Parasaurolophini and Lambeosaurini. It might be more derived than Tsintaosaurini (Godefroit et al., 2004). References:

Partial skull of Shastasaurus pacificus (UCMP 9017) from the Late Triassic of California, USA, in (A) lateral, (B) dorsal, and (C) anterolateral view.

Based on this skull, Shastasaurus has repeatedly been reconstructed with a long, tooth-bearing rostrum. However, note the slenderness of the lower jaw (B, C) and the strong anterior taper of the snout (B), both of which are more consistent with the abbreviated and toothless snout of Shastasaurus liangae comb. nov. than with the traditional long-snouted reconstruction of this skull (as, e.g., in references [22] and [23]).

Des fossiles de poissons vieux de 400 millions d'années révèlent comment la vie a commencé à s'installer sur terre
Australie Chine fossile formation crâne
Les scientifiques ont découvert de nouveaux indices sur certains des premiers poissons de la Terre, mettant ainsi en lumière les origines anciennes des vertébrés qui ont fini par s’installer sur terre. En réanalysant de mystérieux fossiles de la célèbre formation australienne Gogo et en étudiant un crâne de poisson-poumon récemment reconstruit, vieux de 410 millions d'années et provenant de Chine, les chercheurs révèlent comment ces créatures primitives ont évolué.

Le tricératops avait un nez géant qui aurait pu refroidir sa tête massive
fossile Triceratops tomographie crâne
La tête massive du tricératops faisait peut-être plus que simplement montrer ces fameuses cornes. À l’aide de tomodensitogrammes et de reconstructions 3D de crânes fossiles, les chercheurs ont découvert un système nasal étonnamment complexe caché à l’intérieur de son énorme museau. Au lieu d’être simplement un nez surdimensionné pour sentir, il abritait probablement des réseaux complexes de nerfs et de vaisseaux sanguins, et même des structures spéciales qui aidaient à réguler la chaleur et l’humidité.

Cet animal ancien fut l'un des premiers à manger des plantes sur terre
dent fossile crâne
Il y a des centaines de millions d’années, les premiers animaux à ramper sur terre étaient de purs mangeurs de viande, alors même que les plantes avaient déjà envahi le paysage. Aujourd’hui, les scientifiques ont découvert un fossile vieux de 307 millions d’années qui réécrit cette histoire : l’un des premiers vertébrés terrestres connus à avoir commencé à manger des plantes. L'animal, nommé Tyrannoroter heberti, était une créature trapue de la taille d'un ballon de football avec un crâne rempli de dents spécialisées conçues pour écraser et broyer la végétation.

Cet étrange petit dinosaure oblige à repenser l'évolution
os dent métabolisme Dinosauria Foskeia anatomie oiseau évolution mammifères étude crâne
Un petit dinosaure nouvellement identifié, Foskeia pelendonum, bouleverse les idées reçues de longue date sur l'évolution des dinosaures herbivores. Même si les adultes adultes étaient remarquablement petits et légers, leur anatomie était tout sauf simple : elles présentaient un crâne bizarre et hautement spécialisé et des traits évolutifs inattendus. Des études osseuses détaillées montrent que ces dinosaures ont mûri rapidement avec un métabolisme semblable à celui des oiseaux ou des mammifères, tandis que leurs dents et leur posture suggèrent une vie rapide et agile dans des forêts denses.
