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.

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.

bone jaw Cretaceous fossil Mosasaurus new species skull
Fossils collected in Osaka more than 30 years ago have revealed a surprise hiding in plain sight: four previously unrecognized bones from a giant Cretaceous mosasaur. Among them is the first confirmed premaxilla—the frontmost bone of the upper jaw—ever identified in a Japanese mosasaur fossil. Even more intriguing, parts of the skull show unusual anatomical features that don’t match known mosasaurs, raising the possibility that the remains belong to an entirely new species.

Researchers have found strong evidence that original collagen can survive inside dinosaur fossils for tens of millions of years, overturning a long-standing assumption about fossilization. The discovery could unlock hidden molecular clues about dinosaur biology, evolution, and how ancient proteins managed to survive for so long.

Palaeontologists have named a new species of theropod dinosaur from New Mexico. The dinosaur, Dinevenator robustus, lived around 73 million years ago (Campanian faunal stage of the Late Cretaceous). Researchers identified the dinosaur from a fossil skull bone (a frontal) found in north-western New Mexico. It represents a new genus and species of troodontid. Troodontids
