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.

Cette petite griffe dans un fossile vieux de 500 millions d'années vient de réécrire l'origine des araignées
griffe Cambrien fossile spécimen
Ce qui a commencé comme un nettoyage de routine des fossiles s'est transformé en une surprise scientifique majeure lorsque des chercheurs ont découvert une petite griffe dans un spécimen vieux de 500 millions d'années, là où aucune griffe ne devrait exister. Ce détail a révélé Megachelicerax cousteaui, le plus ancien parent connu des araignées, repoussant les origines de ce groupe de 20 millions d'années. Le fossile montre que les principales caractéristiques des araignées et des limules modernes étaient déjà apparues lors de l'explosion cambrienne.

Des abeilles anciennes trouvées nichant à l’intérieur d’os fossiles lors d’une découverte d’une grotte rare
os mâchoire nid proie fossile découverte
Il y a des milliers d'années, dans une grotte d'Hispaniola, une chaîne d'événements inhabituelle a laissé derrière elle un trésor scientifique rare : des abeilles nichant dans des os fossilisés. Après que des chouettes effraies géantes aient amené à plusieurs reprises des proies comme des hutias dans la grotte, leurs restes se sont accumulés dans des chambres riches en limon, créant un étrange environnement souterrain. Plus tard, les abeilles fouisseuses ont profité des sédiments mous et ont même réutilisé de minuscules cavités dans des mâchoires et des os fossilisés comme nids prêts à l'emploi, les recouvrant d'un revêtement lisse et imperméable.

D’étranges roches en « peau d’éléphant » révèlent une vie ancienne dans l’océan sombre
Maroc fossile découverte formation
Une étrange formation rocheuse ridée au Maroc a amené les scientifiques à repenser l'endroit où pourraient vivre d'anciens microbes. Au lieu d’eaux peu profondes et ensoleillées, ces microbes pourraient avoir prospéré dans les profondeurs de l’océan, alimentés par les produits chimiques libérés par les glissements de terrain sous-marins. La découverte suggère que les environnements sombres et riches en nutriments ont abrité des écosystèmes prospères beaucoup plus tôt que prévu. Cela soulève également la possibilité que de nombreux fossiles similaires aient été négligés ou mal interprétés.

Égypte fossile évolution origine humaine
Un singe fossile découvert dans le nord de l’Égypte est en train de remodeler l’histoire de l’évolution humaine. L'espèce Masripithecus vivait il y a environ 17 à 18 millions d'années et pourrait être très proche de l'ancêtre de tous les singes modernes. Cette constatation remet en question l’attention portée depuis longtemps à l’Afrique de l’Est. Au lieu de cela, il désigne l’Afrique du Nord et les régions voisines comme berceau possible des singes.

Des scientifiques ont découvert un rhinocéros dans l'Arctique et cela change tout
fossile datation nouvelle espèce
Des scientifiques ont découvert une nouvelle espèce de rhinocéros dans l'Extrême-Arctique canadien, révélant que les rhinocéros vivaient autrefois bien plus au nord que prévu. Le fossile, datant de 23 millions d'années, est exceptionnellement complet et a contribué à remodeler les idées sur la façon dont ces animaux ont migré entre les continents. Les preuves suggèrent que les rhinocéros ont traversé l'Europe vers l'Amérique du Nord plus récemment que les scientifiques ne le pensaient autrefois.
