    Hi,

    I'm new to this forum and fossils. I am trying to identify some of my finds. I hope the large pictures do not annoy anyone. Any help would be appreciated. How do I determine what time period they date and the kind of fossils?

    I found this one on a beach in Hatillo, P.R. a few years ago. Someone said it looks like the mold of a Gastorpod (Snail), and possibly a Crinoid Stem right next to it and that there may be fragments of Bivalves or Brachiopods, also. Since I found this on a beach, how do I determine the age?

    This is a rock that my son found in a park in southern N.J. Someone suggested possibly:
    Phylum: Bryozoa
    Class: Stenolaemata
    Order: Fenestrata
    ...that is not native to southern N.J. (possibly transported in rock fill).

    I think I found this one in Virginia.

    This bone?!? was found by my son in another southern N.J. park during one of his baseball games.

    Looks like the ID's are good. The rock in the first photos looks fairly recent, probably from a coral reef around PR. The rock with the Bryozoa is probably Paleozoic.

    Nice fossils joecheck, and :welcome: to TONMO.

    Thanks! How recent would you say is the coral reef?

    Also, any thoughts on the other two items (the third and fourth set of pictures)?
