Dinosaur Park Formation in Dinosaur Provincial Park, Alberta
The distictive banding of the Morrison Formation, a group of rock layers that occur throughout Dinosaur National Monument. The formation originated as muds and sands laid down by ancient rivers, and some of its outcrops have been found to contain 150-million-year-old dinosaur fossils like those found at the monument's Dinosaur Quarry.

Wide angle photo from the visitor’s walkway inside Lark Quarry Dinosaur Trackways, Australia. Here, the camera is pointing towards the south west corner of the building. On the top (in the far corner) is the natural landscape. In the middle ground of the photo, some of the overburden has been cleared. In the foreground is the dinosaur tracks.
Bituminous claystone, Lower Jurassic, Hesselberg, Middle Franconia. Sedimentary rock of very thin laminated layers (particles less than 0,0002 mm). Rock formation is known for its rich fossil findings, ex. Ichthyosaur.

Nyasasaurus is a basal dinosauromorph that may be the earliest known dinosaur. It was a small bipedal animal at about 2-3 m in length. Nyasasaurus is difficult to classify due to inconclusive fossil evidence, but if it is a true dinosaur, it pushes the dinosaur lineage back about 12 million years to the Middle Triassic.

Sidersaura is a rebbachisaurid sauropod dinosaur from the Late Cretaceous of Argentina. Rebbachisaurids are the last known dipldocoids, and lived alongside the titanosaurs until fairly late in the Cretaceous before disappearing from the fossil record, presumably going extinct. They have long tails and relatively short necks, by sauropod standards. Sidersaura one of the most recent rebbachisaurids yet found, living in the Cenomanian–Turonian ages of the Late Cretaceous. It was large for a rebbachisaurid, growing to about 20 m in length.

Achelousaurus horneri skull, collected in Glacier County, Montana, at the Museum of the Rockies in Bozeman, Montana. The Ceratopsidae are those dinosaurs with head frills. There are three large subgroups of Ceratopsidae: Centrosaurinae, Ceratopsinae, and Chasmosaurinae. The Triceratopsini are a "tribe" of the Chasmosaurinae -- a genus so vast that it gets the special name "tribe". The Pachyrhinosaurini are a "tribe" within the Centrosaurinae. Achelousaurus is a genus within the Pachyrhinosaurini. So far, only three skulls and some limited skeletal remains have been collected anywhere in the world -- and all of them in Montana. Their bony frills are quite similar to the Styracosaurus albertensis, although their other skull features (such as big bony bosses on the nose and behind the eyes) are not.
Muzquizopteryx coahuilensis (Familyː Nyctosauridae) is a species of nyctosaurid pterodactyloid pterosaur from the Late Cretaceous period (early Coniacian stage) of what is now Coahuila, Mexico.
