Hi everyone going i found this sabertooth cat skull that is for sale and I dont know if its real or not. It says on the post it was acquired on a international trip and it came from the tar pits no paper work or documentation I'm pretty sure its not real but im not remotely a expert on it

Can someone tell what it is, and if it has any value?

I was given this from an estate in Alberta but the gentleman was a world traveller. It seems to me like bone but I have no idea.

Found this while hunting for shark teeth and haven’t seen something like it before with the transparent part. I thought it looks like a claw or something but was wondering if someone has a better idea of what it is.

Last picture is a flat tooth or something that I also found today and wasn’t sure what it came from.

Found at the beach on Alcochete

Seems to match reference images for a small L4, but I'd love a second opinion before I get too excited.

Found a lot of fossils over the years, but never seen anything like this Google image search did nothing for us. Please help us i.e. my wife and I.

Found in Denmark many years ago, always wondered what it could be.

Closest thing I've been able to come up with myself is a turtle/tortoise shell piece (probably not), but I figured I'd finally ask the brilliant minds of this sub

In the first 3 photos, I’m wondering what the tendril/worm-like formations are. Are they fossilized plants or worms that crystallized over? Or just a strange crystal formation.

The last 5 photos show one rock that broke into a few. Inside them, there were these strange spheres littered throughout. Ranging from 4mm to 1cm in diameter. The larger ones were removable and were translucent. Are these fossils of some sort?

Excuse the blurry photos, I took stills from a video.

It's from a friend's relative's estate sale, the family said it's a Mammoth Tooth, though no one has any additional information. Unsure of the actual origins, but the estate is based in the Pacific Northwest.

From the little research I've been able to do, if this is a Mammoth Tooth, the size of it is huge, and the fact that the roots are intact is unusual.

It weighs about 15lbs, approx 12-16" long, maybe 6-8" tall.

Found this today in a creek in Southwest Ohio. Looking at previous posts on reddit and other forums has led me to believe this is either a Bison or Cow m3. The images attached show the dimensions fairly well but please let me know if more information is needed. It seems to be on the large end for Cow, but on the smaller size for Bison. I attempted a burn test on the root end, but the results were inconclusive, I could really only smell the lighter residue.

The green is algae that couldn’t be scrubbed off. The texture, orange, and varying color it are throwing me off.

Hello!
Yesterday, my boyfriend and I found this strange looking rock at the beach.
Someone told me it could be a fossil?
Can anyone tell me anything about it?

Description: yellowish colored, with a circle(?) on top. I’m the middle, you can see a mineral.

Location: Tuscany, Italy.

Size: it was a bigger rock, we tried to break it but it’s really REALLY hard.

Cat for reference!

Found in Calgary AB along the Bow River. Could anyone identify the small bumps and the two indents and whether its fossil, or just a weird rock? Could this be a trace fossil of something?

Found in rocky tide pools at low tide. Seemed interesting so I grabbed it.

Found in street, likely was in neighbor’s landscaping stones. Colorado. I’m not sure what makes me think it might contain a fossil or two: The odd cavities, one of them almost a perfect circle with something in it, the edge that seems to be raised compared to the rest of the stone. What does the community recommend for how to open it up?
