Some Uncommon Extant Shark Teeth 2


MarcoSr

Recommended Posts

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):

I am just loving these new teeth from Your collection!

Thanks for sharing.

 

Thank you.  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.

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.
