Oups je n'avais pas vu les 2 premiers ont déjà été posté dans actualités paléontologiques....

Le petit coelurosauridae est interessant il est assez proche de huaxiagnathus, et semble avoir pas mal de caractéristique différente de la plupart des maniraptora comme quelques unes de ses vertébres.

Camptosaurus aphanoecetes
Carpenter, K., and Wilson, Y. (2008) A new species of Camptosaurus (Ornithopoda: Dinosauria) from the Morrison Formation (Upper Jurassic) of Dinosaur National Monument, Utah, and a biomechanical analysis of its forelimb: Annals of Carnegie Museum, v. 76, n. 4, p. 227-264.
A new species, Camptosaurus aphanoecetes, is named for a partial skeleton of ornithopod dinosaur from the Morrison Formation (Upper Jurassic) of Dinosaur National Monument, Utah. The specimen was originally described as Camptosaurus medius Marsh, 1894, and later referred to Camptosaurus dispar (Marsh, 1879). Comparison of the specimen with a large sample of C. dispar from Quarry 13 shows differences in the proportions and shape of various axial and appendicular elements.
Based on the dorsoventrally depressed form of the ilium, Camptosaurus depressus Gilmore, 1909 (Lower Cretaceous of South Dakota) is assigned to the Barremian genus Planicoxa DiCroce and Carpenter, 2001, as Planicoxa depressa, new combination.
The well-preserved, undistorted forelimb material of C. aphanoecetes allows for a biomechanical analysis. The range of motion is rather limited throughout the forelimb. The analysis supports the quadrupedal locomotion previously hypothesized for Camptosaurus Marsh, 1885, from limb ratios, fusion of the wrist, and presence of short digits.

Je sais bien que tu a écrit ton message juste après mangé mais quand même, un Camptosaurus c'est vraiment un peu trop gros pour confondre avec de la dinde!
