A collection of teeth from a formidable Late Cretaceous lamniform shark. This species competed with other sharks and marine reptiles in the Western Interior Seaway ~ 90 Ma. It likely filled a similar niche that the Great White Shark does today. The ginsu was on average larger than the Great White. Oh, it also ate dinosaurs.
