fossilized6s Posted July 11, 2017 Share Posted July 11, 2017 Found this piece in Iowa yesterday while hunting trilobites. I've never seen anything like it. The six point symmetry with it's bulbous tips are very strange. And the fact that it is very water-worn doesn't help with an ID. I'm thinking holdfast or possibe starfish. What do you guys see?

Raggedy Man Posted July 11, 2017 Share Posted July 11, 2017 Possibly a trace. ...I'm back. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted July 11, 2017 Share Posted July 11, 2017 I could see trace or very very worn and broken starfish, although I'm not ruling out holdfast either. Now that I think about it, I'm really not that helpful. Hmmm...maybe the experts can help. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
fossilized6s Posted July 11, 2017 Author Share Posted July 11, 2017 I don't think it's a trace fossil because of it's different preservation from the matrix. But that being said i still don't have a 100% ID, so i'm open minded. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

Rockwood Posted July 11, 2017 Share Posted July 11, 2017 Just now, fossilized6s said: don't think it's a trace fossil because of it's different preservation from the matrix With you completely on that. That one end in particular is too tube like for this taxa at least. 1 Link to comment Share on other sites More sharing options...

TqB Posted July 11, 2017 Share Posted July 11, 2017 It's close to some types of Brooksella which has more than one mode of origin I think, depending on where it's from. Tarquin Link to comment Share on other sites More sharing options...
fossilized6s Posted July 11, 2017 Author Share Posted July 11, 2017 Thanks for the suggestions, guys. I appreicate it and have looked into all of them. I now am thinking sponge or trace fossil, but i still can't find a 100% match. If anyone else has any thoughts I'm open to suggestions. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
