Are you near the ocean? It looks like brain coral.

Welcome to Treasure Net. I'm not very knowledgeable with fossils but, it looks a piece of Brain Coral to me. You found this near the sea?

i agree with taz...some type of coral...

It's brain coral. You don't have to be near the sea to find it. Someone could have brought it home & put it in the back yard. I do this kind of thing all the time. I have 2 pieces of coral in the yard right now & I'm in the Sierra's.
Also, it could be fossilized & from a time when the land you are on was under water. I'm betting on the first option!

Coral for sure.

Thank you all for your quick responses, I do not live near the ocean. I agree that it was probably put there. Now I'll check out what brain coral is. It is cool looking though, we will add it to our rock and mineral collection.

I used to be a scuba diver, including diving in tropical oceans, so I'm familiar with what you found. I've got several immature (small) examples of it, as souvenirs I found on diving trips to the Caribbean. Here's your answer about brain coral.

"Brain" coral is the nickname given to that particular species of coral for two reasons:
1- When that species grows to its massive (several feet wide) fully-mature size, its form is an oval-shaped rounded-top dome, like a brain.
2- The curving ridges/channels across its surface make it very closely resemble the surface of the human brain.
