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.

The Naturmuseum Senckenberg in Frankfurt is the second largest museum of natural history in Germany. It is particularly popular with children, who enjoy the extensive collection of dinosaur skeletons: Senckenberg boasts the largest exhibition of large dinosaurs in Europe. One particular treasure is a dinosaur fossil with unique, preserved scaled skin. The museum contains the world's largest and most diverse collection of stuffed birds with about 2000 specimens.

De minuscules fossiles vieux de 1,7 milliard d’années pourraient révéler l’origine complexe de la vie
fossile
Les scientifiques recherchent dans certaines des roches les plus anciennes de la Terre de minuscules fossiles qui pourraient révéler comment une vie microbienne simple a fait un bond extraordinaire vers les plantes, les animaux et d’autres organismes complexes. Résoudre cet ancien mystère pourrait également aider à déterminer si une vie complexe pourrait émerger sur des mondes au-delà de la Terre.

os Pléistocène fossile découverte nouvelle espèce
Les scientifiques ont découvert une nouvelle espèce d’amphibien éteinte cachée dans les collections de fossiles de La Brea Tar Pits à Los Angeles. Nommé Spea labreae, le crapaud de la période glaciaire est une découverte exceptionnellement rare : un seul autre amphibien éteint du Pléistocène a jamais été identifié en Amérique du Nord. Ses ossements étaient conservés dans des collections depuis les années 1950 avant qu'un chercheur ne remarque des caractéristiques qui le distinguaient des espèces connues.

os mâchoire Crétacé fossile Mosasaurus nouvelle espèce crâne
Des fossiles collectés à Osaka il y a plus de 30 ans ont révélé une surprise cachée à la vue de tous : quatre os jusqu'alors méconnus provenant d'un mosasaure géant du Crétacé. Parmi eux se trouve le premier prémaxillaire confirmé – l’os le plus en avant de la mâchoire supérieure – jamais identifié dans un fossile de mosasaure japonais. Plus intrigant encore, certaines parties du crâne présentent des caractéristiques anatomiques inhabituelles qui ne correspondent pas aux mosasaures connus, ce qui laisse penser que les restes appartiennent à une espèce entièrement nouvelle.

Les chercheurs ont trouvé des preuves solides que le collagène original peut survivre à l’intérieur des fossiles de dinosaures pendant des dizaines de millions d’années, renversant ainsi une hypothèse de longue date concernant la fossilisation. Cette découverte pourrait révéler des indices moléculaires cachés sur la biologie des dinosaures, leur évolution et la façon dont d’anciennes protéines ont réussi à survivre aussi longtemps.
