M Harvey Posted December 20, 2016 Share Posted December 20, 2016 Any ideas on what this is? It comes from an estuarine upper Cretaceous formation in Eastern Mississippi. The first photo shows the tip of a needle. I'm new to micro paleo and finding it fascinating. Link to comment Share on other sites More sharing options...
sixgill pete Posted December 20, 2016 Share Posted December 20, 2016 Sorry, don't think it is a fish jaw. Looks like a piece of a broken bivalve to me, or some type of shell. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...

M Harvey Posted December 20, 2016 Author Share Posted December 20, 2016 How about this one found at same place magnified 1500x? Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 20, 2016 Share Posted December 20, 2016 That looks like a jaw with teeth.

sdsnl Posted December 21, 2016 Share Posted December 21, 2016 4 hours ago, M Harvey said: How about this one found at same place magnified 1500x? It looked like teeth at first, but on second thought I think both are bivalve hinge teeth--not really teeth, but that's what they are called. They are the things that lock the two halves of a bivalve together and allows it to open and close. Your shells may be in the families Arcidae or Nuculidae, they have a long row of hinge teeth. 4 Link to comment Share on other sites More sharing options...
FossilGuy1024 Posted December 21, 2016 Share Posted December 21, 2016 It might be a little on the large side, but what about a conodont? 1 Link to comment Share on other sites More sharing options...
ynot Posted December 21, 2016 Share Posted December 21, 2016 First piece looks like a shell fragment. Second piece also looks like a shell fragment to Me. There is no differentiation between the "teeth" and the "jaw", they are the same part Tony Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

fossiling Posted December 21, 2016 Share Posted December 21, 2016 Yes. Shell piece. Keep looking! They're everywhere! Link to comment Share on other sites More sharing options...
Innocentx Posted December 22, 2016 Share Posted December 22, 2016 Here is a link for you to look at, M Harvey. I thought of your photos when I saw it. Possibly Scolecodonts, American style. http://fossiilid.info/62 4 "Journey through a universe ablaze with changes" Phil Ochs Link to comment Share on other sites More sharing options...
M Harvey Posted December 22, 2016 Author Share Posted December 22, 2016 Congratulations, I think you nailed it. This is very helpful. I was thinking conodont but the timeline conflicted. Thanks. Link to comment Share on other sites More sharing options...
JohnJ Posted December 22, 2016 Share Posted December 22, 2016 What does the second specimen look like overall? Do you know the name of the formation in Mississippi? The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
M Harvey Posted December 22, 2016 Author Share Posted December 22, 2016 The specimen is barely perceptible with the naked eye. Unfortunately my microscope camera can only take photos at 1500x. The first specimen does look like a shell fragment the second does not. It was found in the upper Eutaw formation of eastern Mississippi. 1 Link to comment Share on other sites More sharing options...
Guguita2104 Posted December 23, 2016 Share Posted December 23, 2016 I vote for bivalve shell piece, as well. Regards, Link to comment Share on other sites More sharing options...
