This was found in someone's yard years ago - there was a large collection of rocks in the yard and my friends had moved in and were clearing the yard and garage and didn't want this rock and a few other items.
about 2" x 3.25" x 3.25"
Hello, Kimberly,
I have reviewed the images you have submitted. An immediate answer is: the example appears to be a coral colony growth surrounding a rounded limestone. I believe it would have been moved to the location you found it, by a person, and not a natural development of the surroundings.
I will have a complete follow-up for you tomorrow.
Thank you,
Amber
