Maureen Posted October 16, 2018 Share Posted October 16, 2018 I found this in my backyard. The previous owner was a rock hound. This rock has so many confounding features: the appearance of asymmetrical sockets or shell inlay, spongy bone and canals for passage of nerves, blood vessels, curious indentations. What is this?

Fossildude19 Posted October 16, 2018 Share Posted October 16, 2018 Welcome to the Forum. This looks like 2 shells that are cemented together. I can certainly see why you might think bone on this.

jhw Posted October 16, 2018 Share Posted October 16, 2018 Oyster shell conglomeration I believe. Looks fairly modern to my eye. 1 Link to comment Share on other sites More sharing options...

abyssunder Posted October 16, 2018 Share Posted October 16, 2018 I'm inclined to say they may be oysters in a nodule, nicely bioeroded by sponges and tube worms, giving it a spongy look. Especially Entobia has this character. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
