Sharktooth Hill Coprolite?

Recommended Posts

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!!

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?

Thanks for the reply.

There are a lot of selenite filled burrows at the site but I have not seen any like this before.

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.

Thank You!

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.

Looks like an Ophiomorpha burrow, to me.

Thank You for the reply.

It does have some similarity to an Ophiomorpha burrow'
