Plesiosaur fossil shows marks of shark attack

Remains of a shark-bitten, 85-million-year-old plesiosaur reveal that around seven sharks likely consumed the enormous dinosaur-era marine reptile in a feeding frenzy, leaving some of their shark teeth stuck in the plesiosaur's bones, according to a new study.

 

The findings, which will be presented at next week's 69th Annual Meeting of the Society of Vertebrate Paleontology, are the first direct evidence of the diet and feeding behavior of Cretalamna appendiculata, a now-extinct early relative of today's great white sharks.

 

The study, which has also been accepted for publication in the Journal of Vertebrate Paleontology, further represents what lead author Kenshu Shimada describes as "arguably the most spectacular case of shark feeding on a vertebrate carcass reported to date."
