Show us your Devonian Epizoans & Pathological Brachiopods!
Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 225 replies

I love finding multiple fossils. I don't just mean multiple specimens in a single rock, I mean fossils that show evidence of more than one life-form. Shells with burrow traces, for one example. Dung beetle balls. Predation marks. And particularly, epibionts. Here I have a fairly ordinary specimen of the brachiopod Tropidoleptus carinatus. Ordinary, that is, until a closer look is taken.... This specimen supported an variety of other critters on its pedicle valve. Whether the epibionts took hold while the brachiopod was alive, or colonized the dead shell, I don't know; I would speculate the former, as the brachiopod is articulated. I think it is likely that the whole living community was buried together by mud. So who's here? Let's take a closer look. We have several examples of Cornulites hamiltoniae. Some are (relatively) large, while others are very small: Two more Cornulites pictures, then we'll see who else lived here!
