Pliosaurus (Luskhan itilensis) lived on the territory of the Volga region in the Hauterivian age of the Early Cretaceous period. Discovered in 2002 by G.N. Uspensky on the banks of the Volga near the village of Slantsevy Rudnik. This is the most complete pliosaurus skeleton found in Russia. This pliosaurus was not a predator and preferred to feed on fish and cephalopods.

The skeleton is exposed in ventrolateral view. The skull has been fully prepared free of matrix whereas most of the skeleton is still in matrix. The left (upper) forefin has been prepared so that it is three-dimensionally preserved and projects upwards. Scale bar represents 20 cm.

Life restoration of the Triassic ichthyosaur Callawayia neoscapularis. Three specimens of this ichthyosaur are known, the holotype, ROM 41993, and two referred specimens, TMP 94.380.11 and 94.382.2. The skull is primarily based on ROM 41993, cross-checked against TMP 94.380.11 and TMP 94.382.2. The vertebral column is based primarily on TMP 94.382.2 as it is the most complete of these specimens, while the ribs were based on ROM 41993. The forelimbs were mainly based on those of ROM 41993, with TMP 94.380.11 used to determine their breadth. The hindlimbs were based on TMP 94.380.11, especially the more complete right hindlimb.
ROM 41993 was cross-scaled with TMP 94.380.11 by the dimensions of the forelimb epipodials, which produced similar vertebral dimensions. The two TMP specimens were cross-scaled based on femoral length, also producing similar vertebral dimensions. Nicholls & Manabe (2001) stated that no wedge-shaped caudal centra supporting a tailbend were found and that there was no evidence of a bend being present, though considered that they might have existed in the gap in the preserved caudals. Since various other Triassic ichthyosaurs have since been found to have tail bends, one was illustrated here. A modest downturn of roughly 15° was illustrated, comparable to that in Guanlingsaurus, and the location of the bend within the gap in the preserved vertebrae matches well with the location of the bend in Guizhouichthyosaurus.

fossile Alnashetri Alvarezsauria Dinosauria oiseau évolution squelette
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.

Un ichtyosaure nouvellement identifié de la côte jurassique du Royaume-Uni est en train de réécrire une partie du manuel préhistorique. Surnommé le « dragon-épée du Dorset », ce reptile marin de trois mètres de long a vécu pendant une période d’évolution mal comprise, au cours de laquelle les principaux groupes d’ichtyosaures disparaissaient et de nouveaux apparaissaient. Son squelette magnifiquement préservé – doté d’un museau en forme de lame et d’un éventuel dernier repas – permet de déterminer le moment où cette transition dramatique s’est produite.

Hesperosuchus était un pseudosuchien (lié aux crocodiliens) qui vivait dans ce qui est aujourd'hui l'Arizona et le Nouveau-Mexique, aux États-Unis, à la fin du Trias, il y a environ 210 millions d'années.  Il s'agissait probablement d'un mangeur de viande et, du museau à la queue, le squelette le plus complet mesure environ 1,2 m (4 pieds), mais d'autres fossiles suggèrent qu'il aurait pu devenir plus grand, jusqu'à environ 1,2 m.

Cela repousse l’histoire des maladies tréponémiques dans les Amériques de plusieurs millénaires et montre qu’elles se diversifiaient déjà bien avant les documents écrits.

L'un des fossiles d'ancêtres humains les plus complets jamais découverts pourrait appartenir à une espèce entièrement nouvelle, selon une équipe de recherche internationale. Le célèbre squelette du « Little Foot » d’Afrique du Sud a longtemps été débattu, mais de nouvelles analyses suggèrent qu’il ne correspond vraiment à aucune espèce d’australopithèque connue. Au lieu de cela, les chercheurs affirment que son mélange unique de caractéristiques pointe vers un parent humain jusqu’alors non identifié, remodelant les idées sur la diversité humaine primitive.
