I just finished cleaning this Heliophyllum confluens (Colonial Rugose Coral) Middle Devonian, Hamilton Group, Jaycox Member. Western New York. 6" x 4" x 4.5" and its covered in epibionts. Most I know - 1. Brachiopod (Petrocrania hamiltoniae) 2. Bryozoa (Lichenalia stellata) 3. Crinoid Holdfast 4. Bryozoa? Coral?_________? 5. Coral (Pleurodictyum) 6. Crinoid Holdfast? Bryozoa (Fenestrate) Holdfast? Any help with numbers 4. and 6. is appreciated.

Hello together, a friend of mine found this beautiful Myophorella in Portugal, I do not have any Information about stratigraphy except that the genus is jurassic till cretaceous. I think the ID to genus of the big bivalve is unquestioned (although a species would be nice.) What I wonder about are the little bivlave-like things clinging to the shell. To me they look more like epibionts than random taphonomic guests, they also look like tiny bivalves. Maybe young of the same species ? Did they grow in that way? I Havent found clusters of Myophorella in a picture search.

Hi all, Upon examining some of my finds from this hunt about a month ago, I realized that there was an anomaly on one of the Neuropteris ovata pinnules. Initially I brushed it off as nothing more than an anomaly, but last night while I was doing some reading I came upon an intriguing paper on insect galls from the Carboniferous. Some of the gall fossils included bore a striking resemblance to the gall on my frond, and so I figured I would make a post to see if any of you had an idea on what it could be. Here is the frond, in full view:

Does anyone know of any instances -- or suspected instances -- of organisms that are known only from associated fossils, i.e. organisms that left absolutely no trace (i.e. 'xenobiont'), but are detectable from various epibionts that were once attached? In the Pennsylvanian of Kansas City, there are thin limestone beds in the lower Wea Shale that contain an abundance of Crurithyris brachiopods and ammovertellid forams that range persistently at least for several tens of miles. From south Kansas City, MO: From Excelsior Springs, MO, approximately

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

This weekend Natalie found an intriguing fossil: a Hypoturrillites whit an epibiont on the shell. I've rarely seen this kind of association and it makes me wonder if the epibiont was already on the shell when the ammonite was alive or dit it grow on it after it fell on the sea floor. If anyone has papers on the subject it would be greatly apriciated ( @doushantuo maybe? )

Hello, everybody! I have been sorting through my wenlock limestone material, Middle Silurian and have a couple of personal problematica. I am wondering if any of you brilliant folks could help me out. Here is an object which seems to be an epibiont on a Favosites coral. 5 mm long and about 1.5 mm diameter at the widest. Is it a cornulitid ? Or a single corallite of Aulopora? Something else, maybe? And another one? On a solitary rugose coral. 3 mm x 1 mm. And an example of Aulopora from Wiki to compare : And a cornulitid that looks

Hello everyone! This past Saturday, Viola and I braved the cold to do some fossil collecting in the south pit of Hungry Hollow near Arkona, Ontario (Mid-Devonian). When I got home and washed up my specimens, I saw something interesting on one of the horn corals - I think it's a brachiopod - am I right? And does anyone know its identity? Thanks in advance for your help! Monica

From a Callovian - Oxfordian site, rich in epibionts, e.g. serpulids. I don't recognize this one, do you?
