Hello! I found these fossils(?) at Estabrook park which is part of the Devonian Milwaukee formation. They appear to be external moulds. These were found near the Lindwurm and Berthelet Members. Are these jawless fish? Big brachiopods? Non-fossils? I’m stumped on these. The formation is known for its plants, giant fungi, jawed and jawless fish, Cephalopods, and Conulariids. So sorry for the lack of scale! I need to start carrying a tape measure with my fossil hunting backpack.

I was wondering if I found an external mould of the Devonian gastropod Platyceras. The fossil curves in the rock which was hard to capture with the lighting. The rock was too big to carry back and I didn’t have a ruler with me so I apologize for lack of scale. Thanks!

Paleozoic rock. I found this looking back through some scrap rocks. I think this is a stone I found some crinoids, brachiopods, horn corals, and a trilobite in before. .75 inches long (sorry for not including a scale in the picture) thanks!

Found this echinoderm in Paleozoic rock. Crinoid calyx or something else?

Found in some landscaping gravel I’ve found boatloads of crinoid stems at. Brachiopods and gastropods are not too uncommon in those rocks. Paleozoic, likely Ordovician-Silurian. -
Hi, I found this external mold shell on Honeymoon beach, Florida USA. It's about 2" long and 3/4" on the widest end. Unfortunately it is broken and worn on the right edge, but I still thought it was a cool find. It's limestone and has about 3 more shell imprints on the flip side (not shown). This was an unusual shape so I made a clay mold to better see the shape (3rd photo)I looked through many seashell books and narrowed it down to Eastern Turritella or Florida Cerith. What do you think?

Could these be oyster or crinoid cast / molds? The rock is around 15" in length. The two large impressions looked around 5" in diamaeter. Sorry no size indicator in photo. I decided to leave this big boy in the creek..long haul back to car Any help is appreciated!

I have never really done any real fossil hunting, but both my husband and I are always interested in the geology and landforms we encounter wherever we go. My husband and I were visiting my parent's home in Grove, Oklahoma, which is about an hour SW of Joplin, MO. They've been working on moving out all the large rocks that naturally litter the lawn and pastureland since they've moved there, so there are multiple random piles of rocks all over the property. I happened to notice some "sparkly" rocks sitting in a wheelbarrow that I thought were pretty, so my husband came over to take a look.
