Californosaurus perrini, an ichthyosaur from the Late Triassic of North America, pencil drawing

Eekaulostomus cuevasae gen. and sp. nov. from the Danian marine deposits of the Belisario Domínguez quarry, near Palenque, Chiapas, southeastern Mexico. 1, General view of IGM 4716, holotype and single specimen known. 2, Idealized line drawing of the same specimen.

a Skeletal reconstruction of A. greppini. Elements preserved in the material and therefore providing information for the skeletal reconstruction are marked in blue. Because much information is missing from the incomplete skeletal material, the dorsal vertebrae, the proportions and morphology of the cervical vertebrae and the skull were modified from Camarasaurus. b Scaled silhouette drawings of Cetiosauriscus stewarti (in black) and A. greppini (in grey) demonstrating the significant size difference between the two taxa. Scale bar is 1 m

Illustration d'un Brontosaure dans l'eau et d'un Diplodocus sur terre. L'idée que le Brontosaure était entièrement ou principalement aquatique est aujourd'hui considérée comme dépassée. L'image d'une queue traînant au sol et d'un crâne semblable à celui du Camarasaurus est également inexacte.
