Comparison of the holotype (BRSMG Cg3178, A and C right surangular, BAS specimen) and referred specimen (BRSMG Cg2488, B and D left surangular, Lilstock specimen) of Ichthyotitan severnensis gen. et sp. nov. To ease comparison, A and C have been reversed. A-B. Lateral view of both surangulars showing same unique shape; note the upturned, almost 90-degree angle bend and the spatulate-shaped posterior end. C-D. Medial view of both surangulars displaying same morphology posteriorly; anteriorly the Lilstock specimen (D) has been heavily eroded and distorted along its length. Note the position of an elongated foramen on the lateral surface (A-B), identified as part of the fossa surangularis that passes through the bone into the Meckelian canal. See also the damaged (?)angular that is articulated with the surangular and defined by a continuous groove (?suture) as seen in Fig 2H.

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.
