Cretoxyrhina mantelli Ginsu shark Niobrara Fm., Gove Co., KS (leftmost 2 teeth) Eagle Ford Group, Sherman, TX (largest tooth) Eagle Ford Group, Dallas, TX (rightmost 2 teeth) 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.-

Hello! I was combing the beach in Ocean City, NJ for sea glass and stumbled across what I believe to be a shark tooth. Based on what I’ve seen online, I’m curious if it is a Megaladon fossil. Any help in identifying this tooth would be appreciated! Measures just about 3.5 cm

Went out to Douglas Point (Potomac River, MD, Paleocene, Aquia Formation) on June 5th, first time taking the kids and we had a great time. Found a lot of sand tiger teeth as is typical. But this one has me a little stumped. The crown seems too wide at the base to be a sand tiger tooth. Could it be a small or juvenile Otodus? Or is it some kind of sand tiger after all?

This may be an undescribed sand tiger tooth, or C. amonensis? I'm leaving it in the matrix, so may never know. It's about 8 mm. -
