RMac Posted January 16, 2023 Share Posted January 16, 2023 I bought this about 20 years ago when I purchased my dinosaur egg. For the life of me I have no clue what it is. It could be a rock for all I know. Any input is greatly welcomed:) Link to comment Share on other sites More sharing options...
Troodon Posted January 16, 2023 Share Posted January 16, 2023 Could be coral but not certain. Let's see what others say. 1 Link to comment Share on other sites More sharing options...

Would it be more appropriate to start a new feed or continue here? I am new and I don’t want to do something wrong. It may not even be a fossil. However, it is the biggest nearly perfectly round something, possibly rock again, I’ve ever seen. Link to comment Share on other sites More sharing options...
RMac Posted January 16, 2023 Author Share Posted January 16, 2023 Here’s another weird one. My papa and I used to collect rocks together. He came home one day and gave me the roundest rock I’d ever seen. I was over the moon and over 40 years later I still am, because it reminds me of him. Anyone have an idea what it is?

ClearLake Posted January 17, 2023 Share Posted January 17, 2023 That is a very round rock! Someone once posted something similar and it was suggested to be a ball mill (which I had not heard of before) which are used to grind and/or mix materials. They are usually made of metal (not yours) or ceramic. I don't know, just tossing out a possibility. It doesn't seem quite perfect enough for a ball mill, but it is very round for a naturally weathered rock, but that can happen. Link to comment Share on other sites More sharing options...
Terminal Stareasaurus Posted January 18, 2023 Share Posted January 18, 2023 I would polish it with some 1500 sandpaper unless of course you're fine with it like that. Link to comment Share on other sites More sharing options...
