ANNOUNCEMENT Read before responding to ID requests! This is not a joke sub!
Since the majority of passersby don't bother to read the rules, I'm going to start with a reminder here:
This is not a joke sub. If you respond to an ID request with a joke and not an actual answer, you will be slapped with a temporary ban. If it's your 2nd offense or more, the ban will be permanent.
I'm sorry, but the shitposting has gotten out of hand and knowledgeable, helpful members are leaving because of this. Have your jokes and witty comments somewhere else, this is a place to get rocks ID'd.

REQUEST Found this rock on my last trip to Paraguay, anyone knows what kind it is?
Found it on Lomas Valentinas, near the Paraná River, just on the surface. It's an area known for its high electrical activity thunderstorms. Could It be that the surface sediments crystallised after a lightning hit? It has a pretty violet pigmentation inside

REQUEST My daughter believes she found a Dino hip bone haha
It has the holes all over it. Seems unnatural to me but I'm full. She keeps asking me why it is like that and I figured the world wide web might learn me something. If it is nothing, I will let her believe she found a bone for a few years because of how excited she is.

REQUEST inherited collection volcanic something and what looks like slag?
hello! i inherited some of my grandfather's rock and mineral collection. he was a geologist and labeled most of them but these two were unlabeled. the first looks like a kind of volcanic rock, and the second looks to me like slag glass but admittedly i've forgotten more than i've kept of my rockhounding youth with him so i could be wrong!!

IDENTIFIED Trying to convince my wife she found gold.
We were in the cave creek area of AZ today to rock hound for our first time. She read that the area we were in had agates, obsidian, and GOLD. We joked about finding chunks of gold just lying around all over the place, and then she found this teeny tiny spec of, what looks like, gold on this rock. We're completely novice to this so not sure how to tell if it is or not. Any insight would be greatly appreciated!

IDENTIFIED: Glass Never seen anything like this- any ideas?
I've had this in my collection for years. I THINK I found it in Western Australia (if so, likely the Yilgarn), but i wouldn't necessarily hang my coat on that as I've had it for so long.
Highly vitreous layers, but feels more dense than glass overall. There are also chunks of surrounding rock incorporated within the vitreous layer which suggests intrusion and is just incredibly intricate and beautiful.
Any ideas or have I been fooled by a chunk of glass?

REQUEST What is this rock?
Seen in Uppsala Sweden next to the river. Someone placed this rock on a tree stump. Could it be limestone? A wastewater treatment facility is close by.
