Ancient shark tooth in whale skull reveals climate-driven ecosystem shifts

Fossil hunters in Antwerp discovered a shark tooth embedded in a whale skull, providing direct evidence of predator-prey interactions from 4-5 million years ago. This discovery offers insights into ancient marine ecosystems and how they responded to past climate changes. Researchers suggest that as whale populations shifted due to climate shifts in the Pliocene-Pleistocene transition, the sharks that preyed on them also disappeared from the region. AI
