GeschWhat Posted February 14, 2017 Share Posted February 14, 2017 I prepped another Niobrara coprolite and found an interesting inclusion. With my limited knowledge of fish anatomy, My best guess is some kind of connecting bone where the vertebrae meet the skull? The coprolite contains both large and small fish vertebrae in addition to this bone. Thanks in advance for your help!

fifbrindacier Posted February 14, 2017 Share Posted February 14, 2017 I tried to look at fish fossils of Niobrara, but i didn't find a match.

I looked through the Oceans of Kansas site, but couldn't find anything either. Thanks for trying!

M Harvey Posted February 14, 2017 Share Posted February 14, 2017 Very interesting find. How did you remove the matrix? Link to comment Share on other sites More sharing options...

LordTrilobite Posted February 14, 2017 Share Posted February 14, 2017 The big bone part looks like a cross section of a fish vertebra. I see this same shape very often in the Cretaceous fish vertebrae from Khouribga, Morocco. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Rockwood Posted February 14, 2017 Share Posted February 14, 2017 This area has the look of the remains of a rounded articulating surface. Link to comment Share on other sites More sharing options...
Carl Posted February 14, 2017 Share Posted February 14, 2017 I also see a split fish vert. Very nice find! Link to comment Share on other sites More sharing options...
GeschWhat Posted February 14, 2017 Author Share Posted February 14, 2017 Yep, I see it now. I tried to take a photo of the side of the intact edge. Even though I had my microscope focused on that area, my phone refocused on edge of the coprolite. I attached it anyway, even though its blurry. I think this coprolite either contains the undigested remains of 3 different fish or there is some drastic tapering of the spinal column. I guess it could also be a result of an animal eating a fish that just ate a smaller fish...like the nesting dolls. Forgive me...I digress. @fifbrindacier Do you still want shots of those areas? Thanks everyone...you are the best! Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
