Dug this up while excavating an area in central Missouri. It was in an area with lots of clay if that matters much. Top Angles: Bottom:

I live in Connecticut and found these artifacts (or rocks). I live in an area frequented by the Tunxis tribe. I cleaned them off with water and a toothbrush. The last one is painted on one side and appears to have a person with a hunchback playing a flute to a bird? It’s only painted on one...

So it doesn’t have any metal in it. It was just in a hole I dug for something else. It looked odd so I grabbed it. I thought it was a rock. But doesn’t seem strong enough for it to be one. Chunks can break off with enough pressure from my fingers. So I have no idea what this thing is. Did I find...

Greetings, On my trip to the country side village we came across very mysterious stones/rocks. Looking at the rocks and passing various tests we found that they are very attracted to nails and iron and steel bars (They are magnetic) and have magnetic features. The Rocks are very hard and heavy...

Hi! So I've been finding these really cool and colorful rocks in eastern WY that are unlike anything I've seen before. Has anyone else? There are obvious fossils in what I think is a form of chalcedony (jasper?) but then there are also these little clear crystal agate pockets. The fossils look...

Hi, so today out in a nearby field i found this rock which looks volcanic to me, but i dont have much experience... Its was found in a field near a city which doesn't have any volcano activity there or even close, in fact the country (Portugal) does not have or had any active volcanoes. The rock...

Posted in Rocks/Gem and didn’t hear from anyone, but did have someone suggest fossilized coral on another website? Curious what this is!!

This rock was actually found in our yard and once we broke it up we found this (see pics). Can anyone tell me #1 What kind of rock this is? #2 Is this unusual? and #3 Is that Gold in it or something else ie. Pyrite etc. Any information would be greatly appreciated. A little background...

I believe these are some form if quartz but cannot find anything that is exactly the same to identify.

My child found this under the tree in our backyard, I think its Anthracite but would like a second opinion. Researching it, Anthracite is found near mountains or up north and im from the gulf coast of Texas so im a bit confused. Thank you in advance.
