Derrik Posted May 5, 2009 Share Posted May 5, 2009 I found this in a creek probably 5 years ago and always wondered what it is. It has kinda a root structure on the bottom of it. I also found this cool Engonoceras ammonite nearby. My first guess is coral. ***Maybe if I resize those jumbo pictures I'll get a responce *** Link to comment Share on other sites More sharing options...

ashcraft Posted May 9, 2009 Share Posted May 9, 2009 I would agree with the crinoid assessment. Brent Ashcraft ashcraft, brent allen Link to comment Share on other sites More sharing options...
Roz Posted May 9, 2009 Share Posted May 9, 2009 I do not know why but am just not seeing anything crinoid-like to me.. I think I saw another one like that with an ID on the web but look at hundreds of pis so not sure I can find it. I could also be wrong.... Welcome to the forum!

fossil_femme Posted May 14, 2009 Share Posted May 14, 2009 sooooo............. What the heck is it??? Don't be shy now. I don't have swine flu... yet. My first thought was crinoid calyx, some of the Paleozoic ones look similar... but unfortunately I know next-to-nothing about the Cretaceous "don’t you lock up something that you wanted to see fly..." chris cornell / soundgarden Link to comment Share on other sites More sharing options...
mstreman Posted May 14, 2009 Share Posted May 14, 2009 I know this will seem far fetched when I state it but it is true. I've seen them in fossil and freshly made. This could be a crab regurgitation/feeding pile. Some crab species (both extinct and extant) sifts through sand and after extracting the tidbits, spits out little spitballs into piles sand castle fashion. Some can be quiet large--the piles that is. They a bit rare but not unheard of. For them to survive they have to be covered by dunes that aren't disturbed for a long while. This was possible during the Cretaceous as the inland seaway retreated. Finding it adjacent to an ammonite of course suggest cretaceous. There are other similar forms which I can't exclude in this id and those are associated with crayfish borrows and a rock lobster/burrowing shrimp-like creature from the late Cretaceous which lined its borrow in balls like this.

fossil_femme Posted May 14, 2009 Share Posted May 14, 2009 Here is where I'm coming from with the "crinoid calyx" guess... not the same type of crinoid, but you can see the similarity.
