Ageleodus pectinatus

Type of arthropod? I was just looking at arthroplueras fosdils on eBay some I'm intrigued! Nice!

Its actually a shark tooth the crown is the serrated bit at the top and the root comes down from that, it does look a bit like some kind of arthropod though!

Just a few miles from where I stay theres Arthropleura tracks exposed on a bed of sandstone on the coast they are over a foot across!

Wow! That tooth is cool. You've got some awesome Carboniferous shark teeth in your galleries.

P.S.

Are these related to the Ageleodus pectinatus teeth from Red Hill, PA? They look similar, and I have seen Ageleodus mispelled as Agelodus.

Thank you =] I had a look at your link, really interesting btw thanks for that! I think that they are one and the same, Ive actually ended up changing the label on this tooth several times already as I keep finding conflicting spelling of the name in literature or that the name has been changed but I think I should go with Ageleodus pectinatus! Heres a link to the site I first identified it from http://www.gla.ac.uk/~gxha14/sharks.html

Its down near the bottom of the list under the name Calloptistalus pertinatus. I was looking at your Pleistocene microfossils earlier, really cool love the ray spine!
