Found this recently on Myrtle Beach while searching for fossils. Thought at first was a sponge or Bryozoa until everyone started saying it looked like a brain (right!!!). Here are a couple of pictures and some magnified images and would appreciate any help. I can’t see typical Zooid but more of what appears to be tangles (sorry for poor descriptions). Fossil is 5cm by 5cm by 3.5cm. Any help is greatly appreciated. Thanks….Lance
@lance-comfort@lmccall@jim-chandler Lance, I had to look that ID up on Google. I’m an invertebrate guy. After looking up Tilly Bone and the more technical term I was still unsure if this thing is some kind of normal fish part or a pathological one. Anyway, a very interesting find.
