Sarcosaurus diagram of known material: reconstruction based on basal Ceratosaurs (such as Berberosaurus and Saltriovenator). The Skull was made to look more generic and less like more derived Ceratosaurs such as Ceratosaurus. "Liassaurus", referred to "cf. Sarcosaurus woodi" and is smaller than the holotype: material in light grey is preserved, but to what extent is uncertain as it is not figured.

About Isisaurus–

Isisaurus colberti (=Titanosaurus colberti) was a species of Titanosaurian Sauropod Dinosaur from the Late Cretaceous (Maastrichtian) age in the Indian Subcontinent. Isisaurus lived sympatrically with another Titanosaurian Sauropod Jainosaurus. It also lived alongside Theropods like Rajasaurus, Rahiolisaurus, Indosuchus etc. Remains of Isisaurus come from the Lameta formation of Central India.

Megapnosaurus is a coelophysid theropod dinosaur from the Early Jurassic Period of Africa. It was a lightly built bipedal carnivore that grew to just over 2 m long and 13 kg in body mass. Its close relation to Coelophysis has caused some confusion in classifying the genus - it had a slender build and curved S-shaped neck, but was more robust. Comparisons between the scleral rings of Megapnosaurus and modern birds and reptiles indicate that it may have been nocturnal.

Des os de dinosaures découverts presque les uns sur les autres en Transylvanie
os bassin Roumanie fossile Dinosauria Titanosauria squelette
Des scientifiques explorant le bassin de Hațeg en Roumanie ont découvert l’un des sites de fossiles de dinosaures les plus denses jamais découverts, avec des os presque les uns sur les autres. Le site K2 préserve des milliers de vestiges d’un lac préhistorique alimenté en crue qui agissait comme un piège osseux naturel il y a 72 millions d’années. Aux côtés de dinosaures locaux communs, les chercheurs ont découvert les premiers squelettes de titanosaures bien conservés jamais découverts dans la région. Le site révèle comment les anciens écosystèmes européens de dinosaures se sont formés et ont évolué au cours de cette période.

crête Crétacé Crétacé supérieur spécimen Canardia Dinosauria Parasaurolophus
Cette semaine, nous allons nous intéresser à un dinosaure à bec de canard très populaire.  Dites bonjour à Parasaurolophus !  Le parasaurolophus était un herbivore qui vivait dans ce qui est aujourd'hui l'Amérique du Nord à la fin du Crétacé, il y a environ 77 à 73 millions d'années.  Le parasaurolophus mesurait environ 9,1 mètres de long du bec à la queue, mais certains spécimens incomplets montrent qu'ils étaient un peu plus grands.  Parasaurolophus est surtout connu pour sa longue crête incurvée qui s'est développée à l'arrière de sa tête, givi

Les chercheurs ont découvert que les coquilles d’œufs fossilisées de dinosaures contiennent une horloge naturelle qui peut révéler l’époque où vivaient les dinosaures. La technique fournit des âges étonnamment précis et pourrait révolutionner la façon dont les sites fossilifères du monde entier sont datés.

Des monstres marins géants vivaient dans les rivières à la fin de l'ère des dinosaures
dent alimentation prédateur Dinosauria Mosasaurus isotope
Les mosasaures géants, autrefois considérés comme des prédateurs strictement océaniques, ont peut-être passé leur dernier chapitre à rôder dans les rivières d'eau douce aux côtés de dinosaures et de crocodiles. Une dent massive trouvée dans le Dakota du Nord, analysée à l'aide de techniques isotopiques chimiques, révèle que certains mosasaures se sont adaptés aux systèmes fluviaux à mesure que les mers se rafraîchissaient progressivement vers la fin de l'ère des dinosaures. Ces énormes reptiles, peut-être aussi longs qu'un bus, semblent avoir chassé près de la surface, se nourrissant peut-être même de dinosaures noyés.

Une momie de dinosaure retrouvée avec des sabots et une crête cachée
crête écaille film Dinosauria Edmontosaurus
Les scientifiques ont reconstitué le profil le plus complet et le plus réaliste d’Edmontosaurus annectens grâce à un processus de préservation extraordinaire appelé modèle d’argile, dans lequel un mince film d’argile a capturé la peau, les écailles, les pointes et même les sabots du dinosaure en trois dimensions. En combinant des «momies» récemment fouillées, une imagerie avancée et une reconstruction artistique, les chercheurs ont révélé une haute crête, une seule rangée de pointes de queue, de délicates écailles ressemblant à des cailloux et, ce qui est le plus remarquable, le plus ancien sabot connu.
