Cari Anne Posted September 17, 2016 Share Posted September 17, 2016 Hi again! Here are the other two items I found (NW PA, along coast of Lake Erie) that I mentioned in my previous post: Item #1: Approx 2" x 2.5" I did some research and I think this is an example of cone-in-cone concretion maybe? Item #2: Approx 9" x 5", I liked this because it had two things going on. I think the one section is cone-in-cone concretion, not sure about the other section? Thank you for taking a look at my samples! Cari Link to comment Share on other sites More sharing options...
Monica Posted September 18, 2016 Share Posted September 18, 2016 Hi Cari! I think your first item is indeed a cone-in-cone concretion (at least it looks like some specimens in other posts that people have identified as cone-in-cone concretions!). As for what you have on the left of your second item (an example indicated in blue in the photo below) - I think it might either be (a) branching bryozoans or (b) ichnofossils (e.g., trace fossils, perhaps the burrows used by little crawly things in the past). Can you see tiny holes in the branching structures? If so, then I'd be pretty confident that they are bryozoans, because that's where the individuals of the colony (the zooids) used to live.

GeschWhat Posted September 18, 2016 Share Posted September 18, 2016 I second what Monica said! Welcome to the forum! 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
TqB Posted September 18, 2016 Share Posted September 18, 2016 Nice cone in cone with ichnofossils - Chondrites kind of thing. (Search images of "Chondrites ichnofossil" otherwise you'll get a load of meteorites!) 1 Tarquin Link to comment Share on other sites More sharing options...
abyssunder Posted September 18, 2016 Share Posted September 18, 2016 I agree. Nice cone-in-cone structures. Documentation on details available for example in this thread : 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
