Mystery Carboniferous Fossil

[Dino2033]

I found this rock in North Attleboro. Massachusetts. It has what I assume is a fossil on it. My best guess would be a seed of some kind but the small circular thing to the right of it is throwing me off. I am away from home right now so I have nothing great to scale it with. The box is roughly 2 inches (5 cm) long to give a sense of scale. I will try to get better pictures when I get back if necessary.

Not enough there to say what it was.

Most likely a shell imprint i get a lot of these in my Carboniferous rocks and a lot of them are smooth so dont leave any distinct features

It seems a bit small for most Pteridosperms, but being so incomplete, and with the way seeds tend to vary in size, I don't think it can be ruled out. I agree that the evidence is not good enough to make an identification, however.

The site is a terrestrial site, and no shells have been found there.

Seed is a much more likely probability.

Why would you? No worries, Brian.

Just wanted to set the record straight on the type of site.

Definitely rules out shell fossils.

Im thinking it probably is a seed too. Looking at it under the microscope hardly gives any more detail.
