PA Fossil Finder Posted February 23, 2014 Share Posted February 23, 2014 (edited) Not to long ago, forum member Caldigger sent me a box of Shark Tooth Hill bonebed material. I finally finished going through it and photographing them today. I only took pictures of the best ones, and I have a lot of other partials. I managed to take these pictures with an extremely simple setup: I cut a hole in the bottom of a clear plastic cup, stuck the bottom of my microscope's lens through it, and voila Feel free to correct me in any wrong identifications. Here are some Squalus to start us off: I think they are S. occidentalis. Here are some basking shark teeth, Cetorhinus: Carcharhinus sp.: Some dermal denticles: Tiger shark tooth, Galeocerdo aduncus: Continued in next post.

PA Fossil Finder Posted February 23, 2014 Author Share Posted February 23, 2014 Heterodontus sp.: I think these are mako teeth: Smooth-hound teeth, Mustelus sp.: Continued in next post. Stephen Link to comment Share on other sites More sharing options...
PA Fossil Finder Posted February 23, 2014 Author Share Posted February 23, 2014 These were identified as houndshark teeth, Triakis sp.: Angel shark teeth, Squatina lericheii: Eagle ray teeth, Myliobatis sp.: I have no experience identifying ray teeth, so I just took a picture of all of them!

old bones Posted February 23, 2014 Share Posted February 23, 2014 Great photos and really cool finds! What a broad range of species in that matrix. I love the ray teeth ... I'm kinda partial to them. Lol I can't see the 2 pics of Carcharhinus teeth. Did they upload correctly? Link to comment Share on other sites More sharing options...

It should be fine now. Stephen Link to comment Share on other sites More sharing options...
old bones Posted February 23, 2014 Share Posted February 23, 2014 Good deal and I really like the dermal denticles too. They are another item that I can recognize. I am still learning shark teeth...sigh... Link to comment Share on other sites More sharing options...
MarcoSr Posted February 23, 2014 Share Posted February 23, 2014 Really nice pictures and a really nice variety of species. Most of the ray teeth are Dasyatis but I can also see several Mobula.

Mediospirifer Posted February 23, 2014 Share Posted February 23, 2014 Cool stuff! I like the variety, and the number of intact teeth. Looks like a very nice matrix to sort through. Link to comment Share on other sites More sharing options...
siteseer Posted April 28, 2014 Share Posted April 28, 2014 (edited) Triakis is the genus for the modern leopard shark, T. semifasciatus and the STH teeth are very similar to those of that species although there has never been a study on that. It might be better to list the STH angel shark as Squatina sp. as there are no unique characters to separate it from other Neogene species (and at some of the others were based on descriptions that would be considered too brief or generalized to be valid). . These were identified as houndshark teeth, Triakis sp.: Triakis.JPG Edited April 28, 2014 by siteseer Link to comment Share on other sites More sharing options...
