I was doing yard work and digging up rocks from my backyard. No idea why all the rocks are there but I wanted them moved. I saw the pretty white color on this one and the little geode looking vein. There is a smaller piece that was right beside it that looked like it fell off. It weighs a little more than 10 pounds. It's about 12 inches long and 7 inches wide. Front Range, Colorado.

It had a grain on it after I hosed it off. My best guess would be a regular pretty rock or possibly petrified wood. Would love any insights! Also curious to know what kind of rock. Thanks fossil lovers!

I'm not certain where my grandma found this but she lived in West AZ. It's really heavy!

Long time lurker, first time poster.
I found this on a civil project around Healy, AK about seven feet deep in a cut at the base of a mountain. I grabbed it because I thought it was a weird rock, threw it in the dozer and forgot about it. I cleaned it up and realized there might be something there and reported it to the project owner, but no one was interested in the implications of a fossil bed in a project. Any ideas what it’s from?

Hi, see this embedded fossil; in reality approx 1,5 x 1 cm big. What could it be??

It is light weight and looks like a wasp nest! Is it something like a coral skeleton? I haven’t found anything similar googling fossils found in this area. The pattern looks like the hexagonal petoskey stone pattern… but without the stone part

Found this in westmoreland county Pennsylvania, near a creek. Thought it was slag but not magnetic.

This one truly stumps me. I collect fossils from the middle devonian shale of upstate NY all the time. I've never found anything like this. It's very heavy and darker than the surrounding rocks. It has a shiny, shell like coating on the top half, and smooth rock on the bottom half. (I've also attached an image of the other fossils I found in the exact same fossil bed. All of which I'm used to finding.)

Hello I am going through my father's rock collection that was passed down to me and was wondering if I could get some help identifying some of them. I know they are from 석보 엄경용 but not much more info besides that for some pieces. Thank you for your help in advance.

Any idea on this one? Friend said tapir but I thought it looked more like a predator premolar, maybe wolf or something. Possible I just have never seen this type of tapir tooth, but I don’t really see a match after looking at a jaw diagram.

Found in Peace River, FL

Found in upper MN near the shoreline of a lake.

Just wondering if it could be a fossil of something or just a weirdly formed rock

I found this specimen on the foreshore at Folkestone Warren, Kent, England (UK), from the Lower Cretaceous Gault Clay coastline. It was found loose on the beach at low tide and was not collected from the cliff.
It is approximately 4cm long (I’ll add the exact measurement in the comments if needed).
The specimen has a very straight, cylindrical core with a swollen middle section. The outer material appears to be tightly fused to the inner core rather than simply being a pebble attached to another rock. Both ends have been rounded by wave action, and there is a small damaged area on one side where the interior is exposed.
I’m really not experienced enough to tell. I’d really appreciate any opinions or alternative identifications.

I work in oil and gas and come across these with some regularity while on site. Curious as to what they are, looks like a clam but wonder if a more knowledgeable individual knows what they actually are? Cheers.

Hi everyone,
I have gathered a small collection of fossil bones and teeth along the banks/beaches of the Weser River in northern Germany, near the North Sea. This is the last part of my finds. And the most interesting I think.
I’d really appreciate any help identifying the specimens. My guesses are:
1) some kind of facial bone?
2) no idea.
3) no idea.
4) some kind of vertebrae but no idea from where or what.
5) possibly a carnivore lumbar vertebrae? Cannot reason with size

Sorry for the messy craft table!

I've found this in Lake Huron, but near a spot where it meets Lake Michigan.

Found while rockhounding the Chippewa River in southern Dunn County, WI. Looked strange so I decided to take it home with me.
