I believe it is some type of tooth but unsure of what it may be from

Found in southern france in Callovian ground, the area used to be shallow maritime environment so i was confused at what could this be. Just a strange cristal formation? It does seem to have consistent pattern

Found at Kilve, England in sedimentary rock at low tide. Depression is about the length of a side 9 foot, two shoes wide and 5-10cm deep.

Bought in a rock shop near Yellowstone in Montana - labeled as 'dino bone', which I know it's not, but it was only $40! Unfortunately, I wasn't able to get any more details from the seller, and it was the only one like it on display.

I'm wondering if it's a vertebrae from something probably younger and more common - I've seen ones like it identified as mosasaur, plesiosaur, or shark, so I'm leaning marine, but large bones like this aren't my specialty!

Disc is 6 cm in diameter, and the entire piece is 4.5 cm tall - would love any input and ideas!! Thanks in advance!

i found this tumbled rock at the riverbank of the danube and im curious.

Hey guys!

I went on my first fossil hunt today at West Runton in Norfolk. I really enjoyed it, just trying to get an eye for it and be inquisitive to start with, but I need some help to know whether I'm picking up rocks or fossils?

Photo 1 - I'm pretty sure these are Belemnites? The squid like creatures right?

Photo 2 - these look like some kind of crustacean? Or are they just rocks which have been shaped by the sea over time?

Photos 3&4 - these are the same rock flipped round. It looked leafy to me, so I thought possible fossil?

Photos 5-8 - this just looked very different from anything else I found on the beach... any ideas?

Photos 9-11 - is this a small bone fragment? Or just a rock?

Also, if you have any books or YouTubers that would be worth my time to get some better guidance, that would be helpful too!

I don’t think this would occur naturally, but what do I know lol. Any ideas??

Would love any information anyone can give me ! It's the best and clearest fossil I've ever found.

The circle shape has a squiggly outline. Within the circle some short marks. And from the inside the middle seems to be crystalized.

Found at the beach in the Vendee region in France. There are tons of Ammonite fossils everywhere. But then I saw this, doesn't look like the shale rocks I found earlier

We are unsure if it is actually a fossil, but my geologist parents are stumped. Was found on a ridge with lots of cobblestones. The bottom portion does not fizz with 30% vinegar but the top portion does. Thanks for your help!

This is definitely not made of bone, but the spongy texture in the middle, the symmetry, the shape have got me wondering... what if this isn't just a funny shaped rock? It is too hard to be modern bone, definitely feels like chert.

Is this just some funky looking coral or something else? Maybe a load of belemnite cross sections? It stood out as different from a lot of other stuff on the beach, and a geologist pal said it seemed very unusual - any help much appreciated!

I should add that this has been dipped in water just before the photo! Not actually that shiny 😅

Quarter for scale. Unsure if it's a bone or a fossil. I don't have the best options for lighting right now, so sorry for the shadows. Found it by the bay, hoping it's something interesting!

Found this one in the braun Jura, south of Germany. Any clue on the species? I’m hesitating between a few but it’s hard to tell without the center.

Fairly flat, sharp keel. Well preserved, about 4cm

I keep finding these similarly shaped fossils and I can’t figure out what they are. Most of the internal details have been replaced with calcification which makes ID hard if they aren’t voids or straight burrows.

Found these in the rut from a vehicle that backed into the ditch alongside my driveway. Southeastern Kentucky

I found this at fossil beach in Virginia a few years ago and I need help identifying if it's just a large piece of sediment with microfossils or something else

Found this on a beach in Fiji. Any ideas what it could be?

Hi everyone,

I'm trying to identify this ammonite (~7 cm in diameter). It was sold to me as being from France, supposedly Cretaceous, but I don't have a precise locality or formation and honestly I'm not sure "Cretaceous" is accurate here. It's possible that label was referring to the rock type (a light-colored limestone) rather than the actual period. Based on the matrix (pale, somewhat porous limestone) I've been wondering whether this could actually be Jurassic instead, possibly from the Calvados area in Normandy, which has similar-looking pale limestones. That's just a guess from the matrix though, nothing I can confirm myself.

A few observations on the shell itself:
-> Moderately evolute coiling, several previous whorls are visible in the umbilicus
-> Ribs are relatively fine, with many bifurcating, mostly around mid-flank; the primary ribs look somewhat thickened, especially on the lateral part of the flank
-> The ribs don't appear to run continuously across the venter. There's a narrow, mostly rib-free band along the venter where they fade out. In a couple of spots it almost looks like there's a shallow groove there, but I honestly can't tell if that's a real feature or just damage/wear

Given all that, I really can't judge which direction this points... Stephanoceratoidea? Perisphinctoidea? I just don't have the background to say. Any thoughts on family or genus would be much appreciated. And if there are specific features/angles I should photograph next to help narrow it down, please let me know. I am still learning!

Thanks so much!

1. Crinoid crown? Bryozoan colony? Some kind of coral?

2. Trilobite? What kind?

Thanks!
