description Allemagne Jurassique inférieur Jurassique +3
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.

Muttaburrasaurus
The plants, animals and climate of the Australian continent have changed dramatically over long periods of time. Imagine this giant creature roaming the luxuriant wet forests that covered parts of the continent in the Cretaceous period, about 100-110 million years ago. The Muttaburrasaurus ambled along on all four legs or stood on its hind legs. Its large teeth were well adapted to eat tough vegetation such as the leathery foliage of the evergreen forests of Araucaria trees, ancient relatives of the bunya pine of south-eastern Queensland.
In 1963, grazier Doug Langdon discovered the fossilised bones of a dinosaur on his property near Muttaburra in central-west Queensland. It was one of the most complete dinosaur skeletons found in Australia. The bones belonged to a new species of ornithopod and palaeontologists named it Muttaburrasaurus langdoni.

Un nouveau genre de dinosaure troodontidé du Nouveau-Mexique
os Mexique Campanien Crétacé Crétacé supérieur fossile Dinevenator Dinosauria Troodontidae nouvelle espèce crâne
Les paléontologues ont nommé une nouvelle espèce de dinosaure théropode du Nouveau-Mexique. Le dinosaure, Dinevenator Robustus, vivait il y a environ 73 millions d'années (stade faunique campanien du Crétacé supérieur). Les chercheurs ont identifié le dinosaure à partir d’un os fossile du crâne (un frontal) trouvé dans le nord-ouest du Nouveau-Mexique. Il représente un nouveau genre et une nouvelle espèce de troodontidé. Troodontidés
