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.

Un fossile de créature marine « une sur un million » préserve les tissus mous pendant 450 millions d'années
tissus fossile Dinosauria
Les scientifiques ont identifié des tissus mous exceptionnellement rares préservés dans un fossile de crinoïde vieux de 450 millions d'années, soit plus de 200 millions d'années plus vieux que les premiers dinosaures. Ses pieds tubulaires délicats offrent une nouvelle fenêtre remarquable sur la façon dont certains des premiers animaux des récifs de la Terre vivaient, se nourrissaient et évoluaient.

Un os fossilisé découvert il y a vingt ans dans le nord-est du Japon appartient à l'un des plus petits dinosaures iguanodontiens jamais découverts dans les roches marines du Crétacé du pays, selon une nouvelle recherche menée par l'Université de Tsukuba. L'article Un fossile d'un petit dinosaure à bec de canard trouvé au Japon est apparu en premier sur Sci.News : Breaking Science News.

Les scientifiques disent que l’arbre généalogique humain pourrait avoir besoin d’une réécriture majeure
fossile
L’arbre généalogique humain pourrait devoir être réécrit en profondeur. Les chercheurs soutiennent que les australopithèques et les paranthropes devraient être regroupés dans le genre Homo, car les nouveaux fossiles ont brouillé de nombreux traits autrefois utilisés pour les séparer. Le remaniement proposé pourrait fournir une image plus simple et plus précise de notre passé évolutif étonnamment compliqué.

chasse prédateur proie Miocène fossile mammifères
L’Amérique du Sud du Miocène regorgeait de proies géantes et les prédateurs qui les chassaient étaient tout aussi spectaculaires. Les marques de morsures fossiles suggèrent que les crocodyliens, en particulier l'énorme Purussaurus neivensis, étaient des prédateurs plus importants que les mammifères dans cet ancien écosystème tropical. Mesurant environ sept mètres de long, Purussaurus aurait même contribué à contrôler les populations d'herbivores géants.
