My daughter typically finds sponge fossils and crinoid fossils at our home here in Iowa. However, she found this little guy and brought it in the house to keep. We aren’t sure what it is. I thought maybe it had a lot of iron in it so I used a strong magnet and it didn’t show any ferromagnetic properties. it looks like small bones all bunched together to us. However it is so much different than what we usually find that we thought we would ask for advice. Any thoughts? Could this be a fossil or just some mineral deposit? we look forward to your responses.
Little ripple marks caused by the gentle currents on the shallow late Ordovician sea floor of Toronto. Georgian Bay formation, Humber member(?), Humber River area, Toronto, Ontario. Limestone slab, the coin is a quarter at the bottom for scale. Hmm, I'm beginning to decide if I should have taken this home with me today. Also at the bottom are two clam negative casts: a Whiteavesia and a Modiolopsis.
