A Couple of Shark Teeth. Cretodus houghtonorum and Turonian Galeorhinus?
EPIKLULSXDDDDD posted a topic in Fossil ID
Hey everyone, Just a quick ID post for help in pinning down what exactly these couple of teeth are. Up first is a broken crown to a tooth I found while processing South Bosque material from Central TX for a pet project of mine. It's Turonian in age and looks similar to some small Carchariniformes teeth I've found at the Whiskey Bridge. Note that when I found this tooth, I had not yet visited the Whiskey Bridge, so I am certain this is not a product of cross contamination. Anyways, it's unlike the other specimens I have from the South Bosque and I am struggling to find a genus that -

I also found some smaller shark teeth including Ptychodus sp., miscellaneous vertebrate material, and ammonites of possibly multiple species. So far this specimen is my largest from the site The first thing I noticed about it w
