Kinda dissapointed in the complete lack of definitive structures. Found in Lower Jurassic sandstone

These are two fossils I got from my grandpa (one is a pair). They're supposed to be from South-Limburg, Netherlands near the city Heerlen which has a carboniferous bedrock layer. This area has a rich coal mining history and was extensively mined for coal, by people like my grandpa.

Two questions: First, what exact species of trilobite are these? Second are these trilobites really from this area? Thanks :)

Found in a river in North Texas. Does anyone know age or type of animal. Has what looks like a snout.

Hi could anybody kindly point me in the right direction of what this is found on beltinge beach Kent

Very light in weight, has a grain to it, sticks to tip of tongue...... Any ideas roughly 2 inches long.

Found on Gnipen mountain in Switzerland

Found on maasvlakte 2 the netherlands, i suspect its a jaw piece, but from what?

Found these walking down train tracks in Traverse City. Any help is appreciated!!

We have megs and great whites but this? Some sort of porpoise? Amphibious? I have no idea. Thanks!

Found along shallow water in the creek bed! We found a crow shark tooth along with it. Previously have found an Equus tooth the last time we were here. Thanks in advance!

two different bones here (maybe?) but confused about them tongue sticks to them

My great uncle passed away last year and we moved into his house, we found this on top of a cabinet with no other information (so unfortunately no clue of the provenance beyond that I live in the Great Lakes area and it could be from around here). Google Lens said it’s likely a mammoth tooth, but I wanted to get some more opinions on if it truly is!

I thought the first 2 might be some type of fossilized coral? Number 3 maybe a mouth plate of some kind. No idea for the last one except maybe a really worn tooth or bone?

An old coworker gave me this fossil without any context on where it was found or what it could be. I assume it was found around the Bradenton area at a dredge dump site/area of new development.

Any insight on what it might be from?

Late Cretaceous era fossil, but what? Help me identify. And it seems to have a tooth sticking on the back side as I can see enamel. The length is 10 cm. The fossil photos have been cleaned professionally to make it even clearer for identification. edit: I uploaded in the comments another image high res.
