  1. possible Ontario river fossils?

    Can anyone identify the possible location where these might have been picked up? These are some of the last remaining unidentified and un-located items that I acquired from the old rockhound couple in Nanaimo, that caused me to come to TFF for ID help in the first place. I'm only getting around to it now. These aren't the most spectacular or important fossils, but it's always worth it if you can attach some info to them. Otherwise I'll eventually toss them out for garden rockery, probably. I thought I saw some similar items that someone had posted not too long ago, from a river in Ontario, in a town that started with P - Pickering? But I never followed up on it and I can't find that topic now. I suspect these are all from the same area, whatever area that is. They're all Paleozoic marine, and all but #3 are water-worn. First: This first piece I have already posted but I never got any confident answers about it. Maybe combined with the others I'll get further with it.

  22. Seed Fossil?

    These 2 are part of a many (50 or more) fossils/imprints I found in a creek bed on a visit this summer to our family farm in Ritchie County, WV. Since we're going back for a visit next week, I thought I'd try to ID these now and look for more while I'm there again. The bulk of the fossils/imprints I've ID'd as ferns, and maybe lycophytes (if my research so far is correct) but can't find anything on the imprints in the attached photos. I'm new to plant fossils, so would appreciate some help in ID'ing this set. Here's what I know: All the fossils/imprints I found, including the attached, were in the same 3-4 meter area along a shallow (1-1.5 meter high) creek bank in Ritchie County, WV; They were found in thick sheets of wet, muddy shale; and The 2 imprints in the photos fit into one another as a match/pair. Here are my questions: What are/were the 2 ovals that fit into one another in the photos? Is there anything else of interest I should be noticing in the attached photos and/or in the other similar fossils/imprints I've found? Note that the last photo are the 2 pieces flipped over. Thanks in advance.

    Hello everyone! I am in the process of investigating the fossil site in Carbondale PA but can't seem to find the exact place where to go or any directions, there were some things I saw on the forum but they look like they are on private property. If anybody knows about it new insight would be greatly appreciated. Thank you.

  25. Bryozoan? Paleozoic/Mississippian?

    Can anyone help me indentify what these are? I’ve found them on a few of the rocks we’ve found, but haven’t been able to figure it out so far. They were found on a bluff in Boone County, MO, in the same area rife with the Crinoids we’ve been finding. I’m thinking from the Paleozoic/Mississippian Era? These are the clearest pictures I could get tonight but, if more are needed, I’m happy to take some in natural light tomorrow. Thanks in advance for your help!
