Hello everybody,
In my forst post, I'm asking you to identify this fossil that I found this summer in a public park of Pittsburgh, Pennsilvanya. I found it alongside rocks dating to the Carboniferous bearing marine fossils (mostly crinoids stems). I have not removed the matrix yet, but the exposed surface of the fossil is less than 1 cm (0,40") long. The magnified pics were taken at 20x.
I can't think of anything that I know of. Can you help me?
Thank you,
Fabio
