MarcoSr Posted April 28, 2018 Share Posted April 28, 2018 I have a large collection of extant shark and ray jaws that I use to understand tooth features. However, a number of tooth features, especially tooth root features, are really hard to see in jaws. So I’ve started to purchase (40+ species to date) and photograph individual teeth of a number of extant shark species. I’ll try to post some of the pictures (labial and lingual views) as I take them. This is another post of three extant species that most collectors don’t see. Centroscymnus coelioepis (Portuguese Dogfish Shark) Upper teeth (5 mm, 2 mm, & 4.5 mm): Lower teeth (4 mm, 5 mm & 7 mm): Scymnodon ringens (Knifetooth Dogfish Shark) Upper teeth (both 7 mm): Lower teeth (13 mm, 8 mm & 6 mm): Somniosus rostratus (Little Sleeper Shark) Upper teeth (5 mm, & 3 mm): Lower teeth (7 mm, 7 mm & 3.5 mm): Marco Sr. 8 "Any day that you can fossil hunt is a great day."

I have a good number of pictures of Carcharhinus species teeth that I'll post in a few days so TFF members can see how different from each other the teeth of some species can look and how similar other species can look.

Regards, Chris Chris The more teeth that I see, the more tooth feature variation that I see within a species and the more overlap of tooth features that I see among different species. So identifying some teeth is actually getting more difficult instead of easier for me. Marco Sr. "Any day that you can fossil hunt is a great day."
