Dinosaur skeleton.

A restoration of Rinconsaurus compared to a human , • Based proportionally on fossil elements and skeletal reconstruction featured in the Rinconsaurus description,[1] with missing parts based on other titanosaur reconstructions. The remains of Rinconsaurus represent two adults and a juvenile all of which are incomplete; some of the proportions shown here, such as the neck, limb lengths, and skull shape are not certain. • Osteroderms are not yet known in Rinconsaurus. The osteoderms shown here are based loosely on Mendozasaurus.[2] Osteoderms are known from at least 10 titanosaur genera spread across the family tree but it's not clear if all titanosaurs had them.[3] Titanosaur osteoderms are rare and their layout and position on the body are not certain. [4] • The colours and patterns, as with the majority of reconstructions of prehistoric creatures, are speculative. • Human silhouette approximately 180 cm tall. NOTE: I often update my images. If you want to have any of my images on a website, please (if possible) don’t host/save it to the website server. I’d prefer it if the image's Wikimedia URL is used. This means that if I update an image, it will be updated on the site as well. Thanks. References ↑ Coria, Jorge; B.J.G. Riga (2003).

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.

Jian is a microraptorine dromaeosaur, and the only non-avian dinosaur so far discovered from the Xiagou Formation of what is now China. Typical of microraptorinae, Jian had long pennaceous feathers growing from its arms as well as its legs, and was small in size, growing to approximately 1 m in total body length.

Brontotholus is a relatively large pachycephalosaurian dinosaur. Like all pachycephalosaurs, it was bipedal and sported the characteristic bony dome on top of its skull. Brontotholus grew to nearly 4 m in length, making it one of the largest known pachycephalosaurs, and the largest from the Campanian age.

Material of the dinosaur Bahariasaurus ingens (1-4, 7-18, 24-26) and indeterminate theropods (5-6, 19-23) from the Bahariya Formation of Egypt.

A cast of BYU 9025, the holotype fossil of the sauropod dinosaur Supersaurus, a giant scapulocoracoid measuring 2.4m long. • The source photo was taken at the Dinosaur Journey Musuem. • Notes regarding the file; This image was edited and extracted from the original seen here. [1] The Photoshop CC lens correction profile and a 'perspective warp' correction were applied.

Digital illustration of the Sauropod Dinosaur Isisaurus colberti from the Late Cretaceous (Maastrichtian) of India (72.2-66 MYA). References include Jain & Bandyopadhyay (1997), several papers from Wilson et al. and skeletal reconstruction by Scott Hartman. Illustrated by Ansh Saxena. About Isisaurus– Isisaurus colberti (=Titanosaurus colberti) was a species of Titanosaurian Sauropod Dinosaur from the Late Cretaceous (Maastrichtian) age in the Indian Subcontinent. Isisaurus lived sympatrically with another Titanosaurian Sauropod Jainosaurus. It also lived alongside Theropods like Rajasaurus, Rahiolisaurus, Indosuchus etc. Remains of Isisaurus come from the Lameta formation of Central India.
