Hi all,
I recently was able to briefly visit the Niobrara chalk beds of western Kansas. However, I know almost nothing about Cretaceous life. I attached a picture of something that may be an iron concretion, but it’s small, disc-like shape made me think twice. I want to see what you all think. Next to the object are several ichthyodectes caudal vertebrae (that’s what I think they are anyway).
Thanks as always!!
