@james-baugh Yes. 100% sure they are brachipods. We are looking at the internal molds. These brachiopods are oriented so the pedicular (ventral) valves are on the bottom. The circular parts are the adductor muscle scares and the part pointing out is the inside of the pedicle foramen.

@thomas-jefery These are internal molds of brachiopods.

@ilyas-soltani You will need to check Belgium’s national and local laws. Many countries have laws prohibiting the sale of objects on public land (without special permitting).

@katie-rider Where was this found? And could it be possible to zoom in to where the bumps are? I’m not 100% convinced it’s Stigmaria (the Lepidodendron roots) because those have indentations. Although the bumps could be a mold (opposite of cast in the preservational sense, not the biological kind)

Hi @waylon-sanders this looks more like a brachiopod.

Hi @andrea-delaparra these look like gypsum chrystals (CaSO4•2H20). They form in arid environments.

@grace-bettenburg It looks like a strophominid brachiopod. Nice find!

@chris-million Sorry, this is a rock. Unlike boney fish (like salmon or pufferfish) sharks skeletons are made of cartilage so they are highly improbable to fossilize.

Hi @steven-l Do you mind providing a close up please?

Hi @claire-challinor it looks modern but I’m not sure. Could you provide a picture of the top please? That is generally the most informative for mammal teeth. Thanks!

@pamela-fabrick No problem! I just checked with my girlfriend (the Mesozoic expert) who said because it has a thick rachis (the stem-y part which is actually a part of the leaf) and thick pinnae (the leafy bits coming off the rachis) it is most likely a cycad. However, she said that Bennettitales cannot be ruled out entirely but there is no…[Read more]

@pamela-fabrick Ok, yes, Northern Alberta would fit! There are a lot of Cretaceous rocks up there. Sadly though, both cycads and Bennettitales overlap in time then. I will show it to someone more familiar with Mesozoic gymnosperms (I work primarily on Cenozoic angiosperms). I will warn you though that the only way to tell the difference might be…[Read more]

Hi @pamela-fabrick this looks to be either a cycad frond or bennetitalean frond. Do you happen to know the state/province/prefecture? I can’t say much without that info. It is a frond (not wood) and it is gymnosperm (not flowering plants and not fern).

@cooper-fry Looks like Alethopteris.

Stigmaria. Root of Lepidodendron. Nice find!

Sorry @amy-sousley this looks like a rock.

@stacy-young Sorry, I think this is a rock.

@mike-reed I think you have part of a sea robin skull (fish). Family Triglidae.

Hi @bernard-weich can you provide us with a little more context please? (Near what city, state/province is it from?)

@joseph-johnson Yes, this is Lepidodendron.
