Ferrodraco lentoni gen. et sp. nov. holotype specimen AODF 876. All preserved elements were photographed and scaled to the same size, then articulated where possible. These were then used as the basis for the scaling of the skeletal reconstruction, the missing parts of which were based on the skeletal reconstruction of Tropeognathus mesembrinus by Mark Witton. Scale bar = 50 mm.

Un ancien crocodile égyptien au long museau réécrit l’évolution
chasse prédateur Égypte fossile spécimen découverte évolution
Un parent de crocodile nouvellement identifié en Égypte repousse les origines des dyrosauridés chasseurs marins de plusieurs millions d'années. Le fossile, Wadisuchus kassabi, présente un mélange de traits primitifs et avancés qui marquent une transition évolutive clé. Des spécimens rares d’âges différents révèlent comment ces anciens prédateurs se sont développés. Cette découverte renforce l’Afrique en tant que centre de l’évolution précoce des dyrosauridés.

De nouveaux fossiles révèlent une branche cachée de l’évolution humaine
dent Éthiopie fossile spécimen découverte évolution
Les fossiles découverts en Éthiopie remodèlent notre vision de l’évolution humaine. Au lieu d’une marche directe depuis des ancêtres ressemblant à des singes jusqu’aux humains modernes, les chercheurs voient désormais un arbre enchevêtré et ramifié avec plusieurs espèces coexistant. Des dents récemment découvertes révèlent une espèce d'australopithèque jusqu'alors inconnue qui vivait aux côtés de certains des premiers spécimens d'Homo il y a près de 2,8 millions d'années. Cela suggère que la nature a testé plusieurs versions de « l’être humain » avant que notre lignée ne perdure.
