Fossilized whale skulls discovered in Belgium, dating back five million years, contain embedded shark teeth, revealing evidence of predator-prey interactions. The findings indicate that sharks, including cow sharks and ancestors of great white sharks, exhibited both scavenging and active predation behaviors in the ancient North Sea.
- 01Fossilized whale skulls from Belgium contain embedded shark teeth, indicating interactions between species.

Researchers have uncovered fossilized whale skulls in Belgium, dating back approximately five million years, which contain embedded fragments of shark teeth. This significant discovery provides direct evidence of interactions between ancient sharks and whales, shedding light on their feeding behaviors. The two species of whales identified include a small right whale and a relative of the beluga. The positioning of the shark teeth suggests that while one whale may have been scavenged post-mortem, another was actively preyed upon, indicating distinct feeding strategies among the sharks. Notably, the study identifies two types of sharks involved: a cow shark and an ancestor of the great white shark. Utilizing advanced CT scanning technology, researchers were able to reveal these hidden details without damaging the fossils, emphasizing the importance of modern techniques in paleontological research. This discovery not only enhances our understanding of ancient marine ecosystems but also suggests that certain survival strategies of sharks have persisted over millions of years.
