Mississippian "shark" Tooth And Micromorph Goniatites

Recommended Posts

Some recent finds. I need to research some IDs further but wanted to share some micromorph goniatites and what looks to be a Deltodus "shark" tooth crown and "root" views.

Thanks Odin of the North. And happy new years!

Forgot to post on in situ picks. I wish I could have kept this stuff in the matrix but I didn't have a dremel with me.

Nice, Tony. I think I have to agree on gastropod as goniatites have sutures (at least the ones I've seen).

Thanks Mike, Tracer.

I think you are right, that these are gastropods. I clicked around the internet and the best "guide" I found was one of Dan's old trip reports from 2004.

One day I should make it a point to read all of them, or at least download.

Generally unless my family is twisting my arm,I avoid collecting too much non shark material unless it is small to store and easy to collect, hence these "little" finds LOL.

Thanks Terry.

Seems like most people selling these teeth lumping them in the "Deltodus sp." category, i.e.

http://www.rhyniechert.com/prospecthillsharks.html

These are probably bradyodont "sharks" which are more closely related to chimeras versus actual sharks.

I plan to do some searching for smaller stuff in the phosphatic material I've collected as I hope to find some "pointy" shark teeth too.

Tony... Well the preservation of the fossils looks very good... Its definately worth searching for a representative sample to see what else you can find...Keep us posted and Thanks for sharing them...
