Reconstruction of the terrestrial paleoenvironmental setting of the Sao Khua Formation by Renata Cunha.
In the center, a generalized spinosaurid feeds on a sauropod. This trophic relationship is hypothesized based on isolated tooth crowns found in association with a sauropod skeleton [67]. In the background, a small pack of the ornithomimosaur theropod Kinnareemimus. Both sauropods and ornithomimosaurs (as part of the “herbivorous” theropods) were found to be positively associated with terrestrial paleoenvironments by Butler and Barrett [15].

Des os de dinosaures découverts presque les uns sur les autres en Transylvanie
os bassin Roumanie fossile Dinosauria Titanosauria squelette
Des scientifiques explorant le bassin de Hațeg en Roumanie ont découvert l’un des sites de fossiles de dinosaures les plus denses jamais découverts, avec des os presque les uns sur les autres. Le site K2 préserve des milliers de vestiges d’un lac préhistorique alimenté en crue qui agissait comme un piège osseux naturel il y a 72 millions d’années. Aux côtés de dinosaures locaux communs, les chercheurs ont découvert les premiers squelettes de titanosaures bien conservés jamais découverts dans la région. Le site révèle comment les anciens écosystèmes européens de dinosaures se sont formés et ont évolué au cours de cette période.

Les scientifiques ont découvert le premier fossile au monde présentant à la fois des caractéristiques de Néandertal et d'Homo sapiens : un enfant de cinq ans de la grotte de Skhul en Israël, datant de 140 000 ans. Cette découverte repousse la chronologie du métissage humain, prouvant que les Néandertaliens et les humains modernes se mélangeaient déjà bien avant les rencontres ultérieures de l'Europe.
