large, unusual bones protruding from the exposed riverbed, prompting a rapid recovery operation that has already secured a jaw, tusks, and several ribs. This find follows a series of recent climate-driven revelations along the river, where receding...

lakeshore, provide a rare look at a hominin species primarily defined until now by its distinctively robust skull and heavy jaw. For decades, researchers have been hampered by a sparse post-cranial fossil record for P. boisei, leaving the species’...

Evolutionary Adaptations Kayrasaurus changliensis is marked by several distinct anatomical features. Most notably, its lower jaw contains more than 45 teeth, the highest count documented in any known member of this group. Furthermore, its neck vertebrae...
