Cretoxyrhina mantelli, Denton Co. Turonian, Cretaceous Jan, 2023 -
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

I have recently found this fossil in north western Kansas (graham co.) I don't know if this is a shark vertebrae/cartilage disk or just a basic fish vertebrae. (Don't mind my bad prep work. I just started peeping fossils recently.)

Eagle Ford Hunt With a Fellow FF Member! Loads of Shark Teeth With Some Unexpected Micro Surprises!
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
A couple of weeks ago, @Jackito, his son, and I took a trip out to one of his favorite Eagle Ford sites. For those of you who are familiar with Carter's posts, this was once the famed location of the so-called "giving rock", so the bar was set high for the day. I've come across some of Austin's eagle ford material in the past, but it was always only the leftovers of what had been washed through miles of rushing creek water. This was my first time getting to poke through the source material, so I was eager to see what could be found. The water was low and the temperature mild. I was thankful I- 22 replies

Cretaceous shark teeth I found in Grayson County, TX
Fatigued_Fossil_Hunter posted a topic in Fossil ID
Eagle Ford Group, Post Oak Creek, Sherman, TX, USA I'm curious to know the identity of these shark teeth so help from experienced fossil hunters would be much appreciated! -

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. -

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.

Closeup of a C. mantelli tooth with unusual wear. I suspect it could be from a tooth in the opposing jaw, or that it may have been bitten in the process of falling out of the mouth during feeding.-
