A hidden diversity of ceratopsian dinosaurs in Late Cretaceous Europe - Nature
New results indicate that rhabdodontids and the previously described Ajkaceratops are actually distinctive European ceratopsians, a group better known from Asia and North America.

Earliest evidence of hominin bipedalism in Sahelanthropus tchadensis
Limb bones of the earliest known hominin, Sahelanthropus, are chimpanzee-like in shape but demonstrate adaptations for bipedalism.

Some days ago I made a thread on Pleistocene crocs in honor of Prehistoric Planet: Ice Age, and now I'm bringing it here too.
Let me prefice this by saying that I of course understand their absence, obviously more unique fauna takes priority and I don't begrudge the team their choice
