Skull of Jinchuanloong niedu (JCMF0132) in left lateral view.

Jinchuanloong is a relatively basal sauropod that measured an estimated 10 m in length. Sauropod skulls typically don't preserve well in the fossil record, but Jinchuanloong is known mainly from the skull, and parts of the neck and tail. Like all sauropods, Jinchuanloong was a quadrupedal herbivore that used its long neck to reach the vegetation that it fed on.

Dinosaur sand sculptures at the Sand Sculpting Australia "Dinostory" exhibit held at Frankston, Victoria, Australia 2008/2009.The sculpture was the created with the combined efforts of an international team of sand sculpting artists: Karen Fralich (Canada) - children playing in foreground; Peter Bignell (Tasmania, Australia) - Triceratops skull and logo; Martijn Rijerse (Netherlands) - Tyrannosaurus rex scene; Jino van Bruissenen and Christina Mija (NSW, Australia) - background panel.

Various fossils pertaining to the holotype of the Triassic ichthyosaur Toretocnemus (originally Leptocheirus, also Merriamia) zitteli. This image is derived from plate 23 in Merriam (1903), done by an uncredited artist. The arrangement of the individual figures has been modified from the original (most notably, figures 3 and 4 were swapped to minimize confusion). Original description: Leptocheirus zitteli n. gen. and sp. Figures reproduced natural size from the type specimen. Fig. 1.— Right side of skull. Fig. 2. — Cross-section of posterior portion of the lower jaw, taken above the point marked A on the lateral view of the skull. Fig. 3. — Cross-section of the upper and lower jaws, taken at the break immediately behind the point marked Sp on the lateral view of the skull. Fig. 4. — Lateral view of an anterior caudal centrum. Legend (modified from original): Ar - articular A - angular D - dentary J - jugal L - lacrimal Mx - maxilla Po - postorbital Sa - surangular Se - sclerotic ring Sp - spenial T - cross-section of tooth X - doubtful element

Mounted replica of a composite skeleton of Edmontosaurus annectens on display at the University of Oxford Museum, Oxford, England. The original skeleton is compiled from disarticulated fossil bones from a bonebed of the Hell Creek Formation, exposed in the Ruth Mason Quarry in Harding County, South Dakota. It is 8.5 m (28 ft.) long and the skull is almost 1 m (39 in.) in length.[1][2] ↑ Dinosaurs in the Museum.
