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.

Ces dinosaures avaient des ailes mais ne pouvaient pas voler
plume fossile Anchiornis Dinosauria oiseau
Certains dinosaures à plumes ont peut-être brièvement pris leur envol, pour y renoncer plus tard. En étudiant des fossiles rares avec des plumes préservées, les chercheurs ont découvert un indice surprenant caché dans les schémas de mue, révélant qu’Anchiornis ne pouvait probablement pas voler du tout. Au lieu du remplacement soigné et symétrique des plumes observé chez les oiseaux volants, ces dinosaures ont présenté une mue désordonnée et irrégulière, ce que seuls les animaux incapables de voler présentent.

Les scientifiques ont découvert de nouveaux indices sur certains des premiers poissons de la Terre, mettant ainsi en lumière les origines anciennes des vertébrés qui ont fini par s’installer sur terre. En réanalysant de mystérieux fossiles de la célèbre formation australienne Gogo et en étudiant un crâne de poisson-poumon récemment reconstruit, vieux de 410 millions d'années et provenant de Chine, les chercheurs révèlent comment ces créatures primitives ont évolué.

Un squelette de dinosaure presque complet découvert en Patagonie aide les scientifiques à percer le mystère des alvarezsaures, un groupe étrange de dinosaures ressemblant à des oiseaux. Le fossile d'Alnashetri cerropoliciensis révèle que ces animaux sont devenus minuscules avant de développer leurs caractéristiques spécialisées ultérieures, telles que des bras tronqués et des adaptations mangeuses de fourmis. Pesant moins de deux livres, le dinosaure est l’un des plus petits connus d’Amérique du Sud.

Une cache perdue de fossiles vieux de 250 millions d’années en Australie a réécrit une partie de l’histoire de la vie après la pire extinction massive de la Terre. Au lieu d’une seule espèce d’amphibien marin, les chercheurs ont découvert des preuves d’une communauté étonnamment diversifiée de premiers prédateurs océaniques. L'une de ces créatures avait des parents s'étendant de l'Arctique à Madagascar, ce qui montre que certains des premiers tétrapodes marins se sont répandus à travers le monde à une vitesse remarquable.

Royaume-Uni Jurassique fossile Ichthyosauria évolution squelette
Un ichtyosaure nouvellement identifié de la côte jurassique du Royaume-Uni est en train de réécrire une partie du manuel préhistorique. Surnommé le « dragon-épée du Dorset », ce reptile marin de trois mètres de long a vécu pendant une période d’évolution mal comprise, au cours de laquelle les principaux groupes d’ichtyosaures disparaissaient et de nouveaux apparaissaient. Son squelette magnifiquement préservé – doté d’un museau en forme de lame et d’un éventuel dernier repas – permet de déterminer le moment où cette transition dramatique s’est produite.
