Nimravis Posted December 6, 2017 Share Posted December 6, 2017 I am going through and sorting out fossils that I collected on a number of road trips that I did this year. I am looking to see if someone, maybe @Peat Burns or @Herb , with experience in the Ordovician from St. Leon, Indiana can confirm what I think may be a couple Edrioasteroid (Isorophus cincinnatiensis). 1 Link to comment Share on other sites More sharing options...
Peat Burns Posted December 6, 2017 Share Posted December 6, 2017 It sure looks like a possible candidate. The third photo has the raised margin, but I can't see the typical raised, sinuous arms. Could you get some oblique lighting on it to perhaps accentuate the contours? Might need some prep. Hope it is. I haven't found an edrioasteroid yet 1 Link to comment Share on other sites More sharing options...
Shamalama Posted December 6, 2017 Share Posted December 6, 2017 I'm going to vote no on the Edrio for both of these. They look like buttons of rock that emulate the shape but do not have any other features. I don't see any arms, or plates for that matter, that suggest them to be Edrioasteroids. 4 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Nimravis Posted December 6, 2017 Author Share Posted December 6, 2017 d@Shamalama and @Peat Burns - I am going to agree with both of you on this. After looking more closely at them, I think that they may just be some type of mold- I was thinking that they were at first because I thought the little spot on both was the anus ( as shown on the Dry Dredgers site), but it that spot is on both sides of one of them- thanks for the input.

Northern Sharks Posted December 6, 2017 Share Posted December 6, 2017 No edrio there. For future reference the anus/periproct is not in the center, but between the arms closer to the outer edge. In Isorophusella, it looks like a pizza. This pic isn't the greatest to show it, but it is below the center 6 There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
Herb Posted December 6, 2017 Share Posted December 6, 2017 Sorry, I don't think they are edrios either.

Yeah, it was a long shot. Good that you picked it up. I don't pick up as many questionable objects as I should, which is probably why I don't have an edrioasteroid yet I'd probably have better luck going back and looking at the thousands of brachiopods I have. I wouldn't be surprised if there is one stuck on one of those that I didn't notice. Link to comment Share on other sites More sharing options...
