Sydneylh Posted May 7, 2015 Share Posted May 7, 2015 Hi everyone! I found these fossils here in Iowa and am wondering if someone could help me out with ID. Also, could someone explain to me how the white stripe-like patterns are formed on the one rock that I am holding in the photo. The flat stone with the two circular indentations follow through to both sides (i took images of both sides). The 2nd and 3rd images show a bunch of dark ridge like structures and I am curious what those are of. The 5th and 6th photos I am wondering what the circular type fossil in the rock is of. Thanks for all your help! Link to comment Share on other sites More sharing options...
JimB88 Posted May 7, 2015 Share Posted May 7, 2015 #3 looks to be the cross section of a brachiopod in chert..and if Im not mistaken, some of the lophophore support are preserved. (thats the feeding mechanism for them btw) Link to comment Share on other sites More sharing options...
Herb Posted May 8, 2015 Share Posted May 8, 2015 Hi, 1 and 2 appear to be a burrow of some type, Can't is 3 and 4, maybe a part of a coral. 5 and 6 is the interior of a brachiopod as Jim says. I can't tell for sure in the last pix, looks like calcite veins running through the rock. My best guesses.
