GallinaPinta Posted January 14, 2018 Share Posted January 14, 2018 So after hurricane Maria at Puerto Rico, I got curious about the small river down the mountain of my backyard so I went down to explore it. To my surprise some boulders tumbled down due to a soil erosion so I started exploring the scene. I found a few rocks that are actually some very peculiar fossils. The thing is that I don't know anything about fossils in PR so I'm going nuts trying to figure it out! Is it some kind of fish? But it's too big to be a fish and the bone-like structure is quite solid. Professionals and expert paleontologists, please help! Link to comment Share on other sites More sharing options...

Coco Posted January 14, 2018 Share Posted January 14, 2018 Hi, By seeing the first pic, perhaps it could be an oyster.

Coco Posted January 14, 2018 Share Posted January 14, 2018 Yes, could be a part of oyster, but we have to wait more informed members... I can't tell your for the age.

I can't tell your for the age. Coco That same rock with the oyster also has something on the top, like some kind of hole that was filled with dirt. It's shiny around it as if it was a cartilage or a bony structure Link to comment Share on other sites More sharing options...

ynot Posted January 14, 2018 Share Posted January 14, 2018 I agree with Coco, pieces of a shell. The hole with a border is a mineralized cavity within the shell or surrounding rock. It has none of the characteristics of bone, fish or otherwise. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Shells of this genus can be nearly 1 m long. And this one could have been grown on a coral head. Age: Cretaceous to recent.

MikeR Posted January 14, 2018 Share Posted January 14, 2018 At first I was going to say oyster but I now think rudist as well. Rudists are bivalves which formed vast reefs in the Caribbean and elsewhere and became extinct at the end of the Cretaceous.
