Identification Cretoxyrhina teeth are simple in design, having a triangular crown with smooth enamel and non-serrate edges, a thin lingual dental band, rounded root lobes, a lingual root protuberance, and no nutrient groove.1,2 Comments This tooth is from a latero-posterior position, given the crown's distal curvature. The chalk preserved this tooth very well - the enamel retains a sharp gloss comparable to that on modern sharks' teeth. References 1. Bourdon, Jim, and Michael J. Everhart. “Analysis of an Associated Cretoxyrhina Mantelli Dentition from the Late Cretaceo

Just a handful of Cretaceous species, most from North Texas. The sea that bisected North America ~85 million years ago played host to a diverse and burgeoning ecosystem that supported many species of sharks. It was likely due to specialization that allowed these sharks to all live in the same place and time. -

A gorgeous tooth from one of my favorite sharks! The enamel isn't polished - the chalk preserves its shine extremely well - it's as shiny as when it fell out of the animal's mouth! -

A beautiful tooth from one of my favorite sharks. This one is extra special because of the self-inflicted bite mark - a gash seen on the left in lingual view. Apparently their bite was strong enough to cut their own teeth! -

One of my favorites - the "ginsu" shark. This one was found at the DFW airport in the 80's. -

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. -

Hi everyone! I went to Post Oak Creek, Texas a few weeks ago and got a decent haul. Including three teeth that I think are from some rare species that I wanted to confirm my id on. I think the first two are Cretoxyrhina mantelii and the third is Protolamna. I'm particularly unsure with the second one since it seems to have a slight nutrient groove. The first one also has damage where there would have been cusps so I'm not sure if it's a different Cretoxyrhina species or a different genus entirely. I'm fairly certain the creek is Atco formation. I know it's either

Identification: ginsu teeth have broad lingual dental bands, rounded root lobes, a strong lingual protuberance in the roots of anterior teeth, smooth crown faces, and no nutrient groove. Notes: Has damage on the lingual side, perhaps a self-inflicted gash as the tooth fell out of the mouth. Otherwise, a perfect tooth with a very sharp point.

I've always been fascinated by the Cretaceous sea and its myriad of terrifying carnivores, many that would've made Jaws look meek. After watching BBC's Sea Monsters, I made it my goal to compile a box of sea monster fossils. I started this journey 10 years ago, and finally completed the box recently. Allow me to present my Predators of the Cretaceous Sea collection, and take you on a journey to the most dangerous sea of all times. The box measures 20.25 inches long. Inside are 24 unique predator fossils. I will introduce them from left to right, top to bott
