I (maybe not so) clearly meant to say rugose coral or rugosa. Rudist is a type of bivalve for those keeping score at home. I'll just slink off and go to bed now. Good night.

It looks like it's been bitten by sand fleas. Seriously though; I think there is a fossil on this fossil. The holes appear to be trace fossils. There may also be a body fossil of an epibiont as well.

Bob Saunders Posted April 19, 2020 Share Posted April 19, 2020 Horn Corals are from the extinct order of corals called Rugosa. Rugose means wrinkled. The outside of these corals have a wrinkled appearance. Link to comment Share on other sites More sharing options...

Bob Saunders Posted April 19, 2020 Share Posted April 19, 2020 in articles they show what we consider here horn corals but, the ones shown are considered bivalves. Here is one I found locally. The horn coral has some matrix cover removed by me. https://www.dispatch.com/news/20200419/geology-ancient-clams-help-measure-moons-ever-changing-orbit Link to comment Share on other sites More sharing options...

Bob Saunders Posted April 19, 2020 Share Posted April 19, 2020 Not far from my house in south west Michigan, USA. From digging a farm pond.I do not know from what depth. The second picture is showing more of the fossil plate or maybe the other side of it. This one is a small part of the back side of the plate. some using a flash.
