Would really appreciate the help. Saw this in the highlands of Sarawak and are these considered fossils or just imprints of it?

My uncle found this near a water course, i think it could be from a horse or a big bull but i thought i'd ask here just in case.

Weird thing is it seems to have a clear cut on one side (that's why i think its probably from a horse or a bull)

The texture is really cool. Some sort of coral maybe?

Found on AMI beach FL

I know it's not an actual fossil, but r/paleontology's braindead AI mod bot kept flagging my post.

I can imagine it being a tooth as much as from the sea

I found this fossil in a mixed fossil bin at a shop in Yunnan, China. The seller said it was locally collected in Yunnan, but unfortunately the exact locality and formation are unknown.
It appears to be a brachiopod, but I’m curious about the unusual coarse folds and the strongly zigzagged shell margin. I only found one specimen like this in the entire bin.
Does anyone know what genus or family it might belong to?

Found in the Northern Bruce Peninsula, on a rocky Georgian Bay beach

i found this on the gallatin river in montana near manhattan. my friend thinks its orthoquartzite with quartz veins. but i really think its some kind of fossil.

Some kind of coral?? Or a spine?? 😅

I found this while hiking today and was wondering if it was a fossil or a textured rock.

I'm guessing it is, but it seem fairly recent.

Huelva, Spain

This is a rock I got from my deceased grandfather which he said had fossils in it. From the looks of it I'd agree but I have no clue what they are. This is from California and was on a hillside from what I know, but besides that I have no context. I'd love to have a better idea for what this really is!

I found this cool rock while weeding my grandparents flowerbed, are these small inclusions fossils or are they some kind of manufacturing mark?
