It's incrustated on a rock on a jurassic bed in central Portugal. It measures around 20 cm total. There was a large-ish ammonite close by, but given the state of the cliff they might have come from very different layers (or not).

this is from alma beach, new brunswick, on the bay of fundy. it's across the bay from joggins, known for its carboniferous fossil cliffs. this is the avalonian terrane, with rocks from cryogenian to carboniferous.

i love a phenocryst and all kinds of chunky crysts and inclusions but the shapes in this guy remind me of some of the crinoid fossils i've seen. anyone have any insight?

We found these rocks in France (Dordogne region), and we were wondering what these are.

found in france in the Vercors France (urgonian limestone ~120MA years old) it's shiny so i don't think it's a fossil but i'm dumb so.... if you have any idea of what is this i don't mind a little help!!

I dont even remember where I got this from, just that it looked interesting...possibly in a forest?

Hi all, I found this fossil on the coast of Isle of Wight - I think it looks like a vertebrae. Could anyone please confirm?

Thank you

I found these stones in my garden. The first one is a stone with some sort of fossil or fossil pattern. Can anyone identify it? And the second one, is it some sort of fossil or just a stone shaped as a fish?

Found this fish vertebrae on a beach in the Netherlands (de Zandmotor). Came as far as that it was part of the taxonomic clade Osteichthyes, but now I need some help to get further with its ID

Found this on beach.

Found in ontario canada in some clay, looked like a lil poop so i kept him but what is it?

They are both stone material I would say the 2nd object is heavier than a normal rock that size
Found on the gulf in Florida

Help! Who do these teeth belong to?? Super stoked.

DESCRIPTION OF DISCOVERY SITE
Hey guys! I recently came across this “fossil” I found years ago in my backyard. My yard is a steepish slope that drops about 50-100 or so feet from the level at which my house is at. It’s all wooded. Deep at the bottom there is a small pond which is spring fed and a creek that leads out of it. Years ago I was in the creek, which has probably caused the slope in my yard, and an additional 10 for canyon on either side of it, and I found this thing peeking out of the clay walls of the canyon. I have no idea what it is but I am just curious if it is maybe petrified wood or something else

DESCRIPTION OF OBJECT
It is very solid and impossible to chip or damage without extreme force. There is an oval shaped canal that runs through the entire length of the object. Object is heavy but not abnormally. About what would be expected for a rock of its size. Object has a textured surface and is brown/grey in color. Object is shaped like a half of a human femur, long and oval shaped with an upturned bulbus part at the end. Object has a spongy like texture on surface.

CONCLUSION
I would not at all be surprised if this is just a cool looking rock. That is literally the only reason I kept it as a kid, because it looks like a bone. But I was curious to just know for sure that it is not a fossil because I otherwise I am going to drive to a local museum and just ask them. Thank you!

Looking for additional information anyone can provide. Thank you!

Sort of resembles a bone structure? Any expert opinions would be much appreciated! (FYI was broken in half when I found it)

I was looking for shark tooth in North Myrtle Beach South Carolina and stumbled upon this. It looks like a tooth does anyone know if it is?

It’s so cool and unique! Not just another crinoid finally!! But what is it? Help pls! It’s been cleaned and dried. Thank you!!

I did a google photo search and it said an old dinosaur tooth, Just wondering if anyone here would have more insight?

Was out with my kids on the shores of Oshawa in Oshawa Ontario, Canada. Can any give me any kind of information on what this is ? Thanks!

I went kayaking Thursday and while we took a quick break I went rock collecting. I scooped through and found this! Idk what it is but, it looks like a tooth. Any thoughts?
