Second batch of fossils. Odd imprint.


Icestar

Recommended Posts

Time for the second batch! Hopefully these should be a little more interesting than the medley of corals from two days ago, but there are still a few corals to be identified. 

 

At any rate, I have a weird imprint fossil here that I'm not sure of. Probably from the Michigan/Indiana area like the others. Any ideas?

May we know the location?

Life started in the ocean. And so did my interest in fossils;).

Looks like a mold of a spiny brachiopod.

My bad! It's probably from the Michigan/Indiana border. That's where the majority of my finds were from. Unfortunately, since it was found some time ago, I can't be 100% certain.

I agree with spiny brachiopod impression, although the last image looks like it has the classic "sunflower" pattern of a Receptaculites/Fisherites, which might just be a trick of the light.

I can't clearly understand the features of the "imprint", but I'm inclined to believe that the specimen could be close to a eroded receptaculitid, maybe the inner side of it showing the wall structure,  something in the line of Ischadites / Selenoides or relative. An in-hand inspection might reveal more details.

This topic might be on help.
