LabRatKing posted a topic in Fossil IDOK gang, this one has me stumped. This is the last specimen from last year's final trip to the Kiewitz shale, Stoner Limestone, Stanton formation along the Platte River in Cass County Nebraska. I thought at the time, and until a few hours ago, that this was one of the disc shaped oncolites that have been found at that site and related sites in the area. I was playing with a recently LED upgraded microscope and found it had cellular structure barely visible. so I decided to do a laborious prep on it with a bicarb blast. It is in fact nothing I have ever seen be
Hi all, I found this what I believe to be a conularid between Brownville and Peru Nebraska in what I believe is part of the Dakota Formation (nearshore Cretaceous) however to my knowledge no Conulariida have been described in Nebraska Cretaceous material. There are also outcrops of Permian limestone (part of the Stanton formation) present where I found this, but this is the wrong type of rock for that. I’ve never found a conularid before, so confirmation of that would be helpful! (Also ruler is in inches)
