I've received a couple nice Upper Ordovician additions to my collection courtesy of @JUAN EMMANUEL and I'm finally posting them now... (Thanks Juan!) First, is this Tentaculites or Cornulites? I wish I could get better pics. Manitoulin Fm, Hamilton, ON.
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 a bit similar : I would be very grateful for any help. Then there is this. Is it the worm Keilorites? Length 1.9 cm, width 2.5 mm max.
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!
