Coprolite?

Recommended Posts

Hello, two days ago, my brother found this fossil-looking thing near his elementary school in Hamilton, NJ. I thought it was a coprolite after seeing a picture that look almost exactly like it, the same type of rock, size, and even the lines going across it. At first, I thought it was a trilobite, because of the segmented shape, a "cephalon" lobe in the front with a large "pleural lobe" in the back. But that isn't very likely (I guess), because only a small portion of my area has Cambrian age rock. The whole rock looks like it's made of even smaller rocks.

If it was anything other than coprolite (like a fossil of a living thing), then I would say that the left side would be the front. Sorry that you can't really see the ruler. It is 1 and 1 half inches long.

I hope two pictures is enough for a start, but I will try uploading more later. Thank you in advance!:)

I can't see this as being more than geologic, but I know very little on how to properly identify coprolites (and I know it does not resemble any of the coprolites in my collection). I think a job like this calls for the expertise of @GeschWhat! :)

Looks to me like some worn quartzite or sandstone.

It could be a concretion with iron content, so I agree with Tony on this one.
