ynot Posted January 4, 2017 Share Posted January 4, 2017 Hey Hi again, Here is another oddity that has shown up in the buckets of stuff I collected at Sharktooth hill. Not sure when it was found or which site on the Ernst quarries it was found at. I know it is a manganese concreation, but it has an unusual amount of bone pieces and a fish tooth mixed in on the surface and the sape is atypical of the other pieces of manganese that I have seen there. I was thinking it is a manganese replacement of a fish excrement. What do Y'All think? scale is an inch ruler. Thank Y'All!! Tony Darwin said: " Man sprang from monkeys."

Carl Posted January 4, 2017 Share Posted January 4, 2017 Boy, I'd sure love that to be a coprolite. But it just doesn't measure up. Might it be a burrow cast that filled with detritus that included bone bits? 1 Link to comment Share on other sites More sharing options...

GeschWhat Posted January 4, 2017 Share Posted January 4, 2017 Hey Tony, It could be a coprolite, but it looks like there is still some matrix on it. As a general rule, if the material is grainy (comprised of clastic grains), it is not a coprolite. I would take a soft tooth brush and some water to it, or you could scrape away some of the matrix from a small area with an x-acto blade. Once the matrix is removed, you should be able to tell whether or not the material is granular by looking at it under a microscope. If it is granular, I'm in the burrow camp. 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...

Will try to clean it some more and get some micro pictures of it. Please stand by and be patient - it may take a few days. Tony Darwin said: " Man sprang from monkeys."

abyssunder Posted January 4, 2017 Share Posted January 4, 2017 Looks like an Ophiomorpha burrow, to me. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
