FossilFisher Posted December 12, 2012 Share Posted December 12, 2012 Hey all, thought I would share some photos with you and get a few questions out. A while back I found a peice of gravel in my driveway that comes from a mine in my area. One of the few underground limestone mines in Iowa, Ames Mine (Martin-Marietta). See the topic tags for the type of limestone it most likely is. Anyhow, most of it is pretty devoid of any fossils, its a gray (mostly oolitic) limestone, some of it dark gray, some of it light. This peice of gravel popped out of the mix, its as far as I can tell a aquatic snail. The outside was beat up so I decided to take it to a grinder and flatten it to bring out the spiral in it. The front gave a pretty nice spiral, and I went to do the back of it, and apparently it got squashed pretty flat. A crinoid stem is there and under the microscope I found some pretty interesting tiny fossils. The square one seems to be a blue green alga, and a very tiny gasropod in the next. I know that flattening the snail itself ruins all posibility of identification, but I'd have never seen the small ones if I hadn't. Any ideas? Note: the circle of the microscopic images is 2mm. The whole thing is at longest 3cm. Thanks in advance, you guys rock. Pun intended. Link to comment Share on other sites More sharing options...
