deepblue Posted February 8, 2017 Share Posted February 8, 2017 Hi, I came across this site last week and though it might be a good place to help me identify my latest find. While excavating for an addition on my house, I found these two fossils at about the same time in the same location. The one on the right is a trilobite, however the one on the left is the fossil I’m having trouble identifying. My property is located in southwest Michigan, in an area known for glacial deposits, so it makes it a bit challenging to determine what period the fossil is from since it may have traveled many miles before it was deposited. I have found many fossils on the property (almost every time I dig), but this one has me somewhat stumped. I’m pretty sure the substrate is marshall sandstone. In one of the photos looking at the center axis, it appears to have been agateized. Thanks for your help. Link to comment Share on other sites More sharing options...
abyssunder Posted February 8, 2017 Share Posted February 8, 2017 Welcome to the Forum! What is sticking out from the matrix in the right picture could be a trilobite pygidium. 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.

Fossildude19 Posted February 8, 2017 Share Posted February 8, 2017 Welcome to the Forum. I agree - the one on the right is a trilobite pygidium in a nodule - the whole thing could be there under the matrix. The other item I believe may be an orthocone cephalopod, that has been water worn and geodized.

Pumpkinhead Posted February 8, 2017 Share Posted February 8, 2017 If I had to guess, I would say that these fossils are Devonian. Link to comment Share on other sites More sharing options...
Herb Posted February 8, 2017 Share Posted February 8, 2017 I agree with Fossildude19's ID "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.
