Map of Cretaceous-aged dinosaur fossil localities of Mongolia. Gobihadros mongoliensis was collected from Bayshin Tsav in Area C. Open squares indicate Late Cretaceous sites, solid squares represent Early Cretaceous localities. Abbreviations: A, Localities of Western Gobi Desert in Mongolia, mainly group of localities of Nemegtian age (early Maastrichtian), Late Cretaceous; B, Localities of Central Gobi Desert in Mongolia, mainly Djadokhtian age (Campanian), Late Cretaceous; C & D- Localities of Eastern Gobi Desert in Mongolia, mainly Baynshirenian age (Cenomanian-Santonian), Late Cretaceous. Figure has been modified from Tsogtbaatar et al. 2014, Figure 1 [24].

Figure 2: Fossil vertebrate locality of Eric the Red West. Shore platform looking west, showing undulating erosive boundary (solid white line) between the top of the Anchor Sandstone (AS) and the base of the ETRW Sandstone (ES). White dashed lines indicate selected bedding surfaces. White scale in mid-ground (indicated by arrow) equals 1 m.

Représentation du dinosaure Dinevenator robustus, récemment découvert. Ce troodontidé a été identifié en 2026 à partir d'un fossile collecté dans le comté de San Juan.

A broken concretion with fossils inside; Late Cretaceous Pierre shale, near Ekalaka, Montana.

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.

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.

Fossil at the Museo Argentino de Ciencias Naturales in Caballito, Buenos Aires, Argentina.

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.
