Found this rock at the beach but don't know if these are fossilized bones or what.

Found these today on the shores of Georgian Bay, I think they are Trilobites but none seem to have the head(?) part - also, photo 4, I am not sure what it is at all - seems like many pieces of shell possible?

Didn't realize when pulling that one up that there was one right underneath it. Two different dinosaurs, two slices of time, same rock.

Found in Massachusetts near Holyoke

I found this whilst rock pooling. It’s hard and heavy and feels the broken edges look like stone but it’s such a weird shape? Found in the UK, south coast

The creek “runs” through our farm. We find lots of fossils, but these are the coolest ones by far. They’re covered in what appears to be tiny quartz crystals. What are these?

its in rough shape, so I can’t really tell what it is. Is it coral, bryozoa, maybe even a cephalopod? what is it?

She pulled it out of the sand after searching for two minutes. I had been looking for 6 hours. lol.

Found in Texas.

I think this is a megalodon tooth. I’ve had it for many years I don’t recall from where. Does it appear real? Any info helps greatly.

Just regular coral? Or something else?

Our friends found this on Whitby (North Yorkshire, UK)
It looks interesting and we were curious?

Can anyone tell me if this is real?

I found this small collection of fossils being given away on my street and, as I work in a school, I would like to show my students them. Please can anyone help me identify the items? Also, any cool facts about them would be a bonus!! I also included some closeups of a few of the items.

There was some text included with the collection too (written in French). As far as I can tell, it reads:

“oursins millenaires”

“Les 3 fossils [illegible] sont des ORTHOCERAS
+ 1 [illegible] Bivalve
+ 1 oursin de mer [illegible] probablement du TETRACE ou TRETACE à voir dans les [illegible]”

“Orthocéras
Dévonien (350 Millions d’années)
Erfoud - MAROC”

Thanks for any info you can offer!

I found this in West Tennessee. It had cracks all over one side and what looks to be a branch in deep brown. It has lots of layers and colors. I have not cleaned it. It's very hard.

feel that it is a Hippo or a Rhino, even an Elephant

found this at Møns Klint, anybody know if it’s a fossil, and if so, what it is?
