Hi again from Essex, I have found on our beaches around Clacton many pieces of sea floor following the recharge of these beaches with all types of shell remains in them but I cant find any reference on line as to what these inclusions once were or a related date, the first two seem to be in very hard sand stone while the third looks to be in a mud stone, any help would be much appreciated, many thanks
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.
