Skeletal reconstruction of Stenonychosaurus, based on all known material, with missing parts of the skull and vertebral column based on Saurornithoides.[1] This version is modified from a version which was itself modified with red colour to show the known parts of the new genus Talos.
In 2000 a virtually complete Scelidosaurus skeleton was discovered in England. This fossil's hundreds of armor plates and spikes are preserved in their life positions, providing extraordinary details about how this dinosaur looked. St. George is the only place anywhere in the Western Hemisphere that the 11-foot long Scelidosaurus replica has been on display. The St. George Dinosaur Discovery Site at Johnson Farm (St. George, Utah) is home to exceptionally well-preserved dinosaur tracks, some displaying skin impressions. These tracks, along with hundreds of fossil fish, plants, rare dinosaur remains, invertebrates traces and important sedimentary structures, show evidence that this site was produced along the western edge of a large, Early Jurassic (age between 195-198 million years ago) freshwater lake named Lake Dixie.

The skull of a Chasmosaurus mariscalensis, on display at the Texas Memorial Museum. Chasmosaurus was a Cretaceous ceratopsian of North America. This specimen was discovered in Brewster County, Texas.
An Ankylosaurus head (cast of specimen AMNH 5214), on display at the Museum of the Rockies in Bozeman, Montana. This is from a specimen collected in Custer County, Montana. The Ankylosauria were armored dinosaurs that lived from 122 million years ago to 66 million years ago in western North America, Europe, and East Asia. There were two subgroups: The Nodosauridae and Ankylosauridae. The Ankylosauridae contained six species, and a single subfamily -- the Ankylosaurinae. There 18 genus within the subfamily, of which Ankylosaurus is the best known. Ankylosaurus as the last of these, and lived 65.5 to 66.5 million years ago. Ankylosaurus was about 20.5 feet long, 5 feet wide, and 5.5 feet tall at the hip. It walked on all fours, with the rear legs longer than the front ones. They ripped vegetation, and swallowed it whole. Their defining feature was their armor. They body was covered in thick, heavy bony plates, and most of the plates were fused together to make them even stronger. Embedded in the skin were more knobs of bone, and the outer skin above these knobs covered in keratin (the same stuff fingernails are made of). Ankylosaurus had a tail club, which consisted of several large osteoderms fused to the last few tail vertebrae. Ankylosaurus was discovered in 1908.

Struthiomimus altus complete reconstruction in the Rocky Mountain Dinosaur Resource Center, Woodland Park, Colorado
The official postcard (of the American Museum of Natural History) says this is a Barosaurus, and that "this unique freestanding mount is the only Barosaurus on view in the world". This was true until the installation of another Barosaurus specimen at the Royal Ontario Museum. The adult specimen pictured is AMNH 6341, classified as Barosaurus lentus. The juvenile specimen (AMNH 7530), originally classified as a juvenile Barosaurus, has since been reclassified as a specimen of Kaatedocus siberi.
