ive had this fossil laying around for a couple years now. i found it at a construction site where they were excavating layers of what looked like sandstone/siltstone layers. i happened to see this little baby before it got ruined. didnt find anything else though, although if you look close its in a layer with lots of little fossils. unfortunately the rock is beginning to crack. and the fossil itself also has a crack. can anyone identify the species and date this fossil? I bet its at least HUNDREDS of years old. Oh yeah, the fossil is about 3" long.
