I'm new to /sci/, so forgive me if I break some unspoken rules y'all have, but I need some help, and I would greatly appreciate any geologists or anyone knowledgeable in these things around to help me?

Back when I lived in Ohio I went camping in the forest alone, and I found myself taking a midnight walk around the little glen I set up camp in, so I sat down and looked up at the full moon, but a sharp rock poked my arse, which did sting a fair bit.
So I pick up the rock to chuck it into the woods, but I get a weird /x/ feeling and decide to stick it in my bag. I checked it back at the fire, and it had this weird little structure on it! I have zero clue what it is, but it looks to my untrained normie eye like an egg, or perhaps a very specific crystal formation. I have not been able to find any info on it, but it still stumps me. What is this Alien lookin thing? penny for scale

It's a dragon egg anon. Set yourself on fire while holding the stone and become the Mother of Dragons

looks more like a xenomorph egg to me, kek

please, I really want to know what this is. There is the tip of another, rock encrusted one about a centimeter away, and the rock it is in is very porous and light. The actual structure is much more dense, almost seems like another type of rock entirely. much fewer air pockets, if any

So, I'm going to make some guesses. You were off in the forest so I'm going to assume it's not man made. So you have what looks like a chert nodule in a sedimentary rock. The rock is porous so I'm going to guess that it's a calcite which has been exposed to the atmosphere for some time and begun to erode. So a chert nodule in a calcite matrix. It's well rounded so I don't think it was formed in situ. Most likely transported and interred. Possible example of ancient beachrock.

Unfortunately since it's float, I can't tell you anything else.

If dubs it's a primordium of prehistoric shroom

it's not round, more geometric in shape, as some clarification. still think you're right, though it is perfectly symmetrical and even, not an unequal side on it, if that changes things

Rounded in geology doesn't mean round. Sorry for the confusion.

It's a conglomerate rock.
