Fossil Hunting trip for All Upper Cretaceous
Slow Walker posted a topic in Fossil Hunting TripsGoal: collect all Pierre Shale formation main fossil specimens. During my fossil hunting trips I collect a lot of different fossils but never take the time to figure out what it is exactly. Here I will record my trips and finds but more importantly try to identify what it is. This list will encourage me to not just look for the big marine reptiles but also smaller things I normally ignore. I understand how unrealistic this goal is but it's fun. Any feedback or suggestions are welcomed! Specimens shown on wiki for Pierre shale. Marine vertebrates

Possible shark tooth?
sharkysaurus posted a topic in Fossil IDI found this tooth today in Colorado Springs. In the Pierre Shale formation. It looks very shark tooth like. I prepped it out a bit to expose it more. I think it might be Pseudocorax granti ? ... but I'm not sure. Could this be a shark tooth and if so what species?
A couple of Nautilus
RJB posted a topic in Fossil PreparationHere are a couple of Nautilus I have finished up. The small one is from the Fox Hills Formation, the bigger one is from the Pierre Shales of eastern Montana. The really neat thing about the bigger one is that its in its own concretion. Very very hard to find one like that! First one ive seen! Oh, a bit over 6 hours of prep for the bigger one. RB
