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]).

Pendant quinze ans, les Denisoviens n'ont eu ni visage ni contour. Juste de l'ADN extrait d'un fragment d'os sibérien grand comme un ongle. En 2025, un crâne exceptionnel découvert en Chine a tout changé. Homo longi, surnommé l'Homme dragon, donne enfin un visage à ce groupe humain fantôme.

Ce poisson préhistorique pourrait expliquer comment les animaux ont marché pour la première fois sur Terre
Antarctique crâne
Les scientifiques ont examiné l'intérieur du crâne d'un poisson de l'Antarctique vieux de 380 millions d'années, étroitement apparenté aux premiers animaux à avoir marché sur terre, révélant des indices surprenants sur la façon dont la vie a commencé à sortir de l'eau. Grâce à l’imagerie neutronique avancée, les chercheurs ont découvert que Koharalepis jarviki possédait des caractéristiques adaptées pour vivre près de la surface de l’eau, notamment des ouvertures dans son crâne qui auraient pu l’aider à avaler de l’air et un organe sensible à la lumière lié aux rythmes jour-nuit.

Les petits bras du T. rex pourraient avoir évolué pour une raison étonnamment brutale
mâchoire membre chasse prédateur proie Dinosauria crâne
Pourquoi le T. rex avait-il des bras si petits ? Les scientifiques pensent désormais que c’est parce que sa tête géante est devenue l’outil de chasse ultime. Dans plusieurs groupes de dinosaures, des crânes plus forts et des mâchoires écrasantes ont évolué parallèlement à des membres antérieurs rétrécis, en particulier chez les prédateurs chassant d'énormes proies. En d’autres termes, une fois que la morsure est devenue suffisamment mortelle, les bras ont peut-être cessé d’avoir de l’importance.

fossile Dacentrurus Dinosauria Stegosauria découverte évolution crâne
Une découverte spectaculaire de dinosaures en Espagne donne aux scientifiques un nouveau regard rare sur le monde des stégosaures. Les paléontologues ont découvert le crâne de stégosaure le mieux conservé jamais découvert en Europe, appartenant à l'emblématique dinosaure plaqué Dacentrurus armatus, qui parcourait la Terre il y a environ 150 millions d'années. Parce que les crânes de stégosaures sont extrêmement fragiles et ne survivent presque jamais intacts, le fossile aide les chercheurs à découvrir des détails jusqu'alors inconnus sur l'évolution de ces géants blindés.

Des chercheurs de Virginia Tech (Virginie, États-Unis) ont identifié une nouvelle espèce de dinosaure du Trias supérieur.  Le dinosaure a été nommé Ptychotherates bucculentus.  Ce nouveau taxon de dinosaure carnivore a été érigé sur la base de l'examen détaillé d'un fossile de crâne incomplet, bien conservé mais mélangé (numéro de spécimen CM 31368).  Le crâne provient de la Coelophysis de renommée mondiale
