Cephalopods You Say?

Finishing up April in style this week is going to be quite a bit of fun. Rather than discussing a single genus or species, this week is more about an entire subclass of Cephalopoda that we collectively call ammonites (officially Ammonoidea). A single species of ammonite could be discussed at any point, but looking at the evolutionary steps of these rather awesome looking fossils instead is going to be a lot more fun. Just to get people excited, check out the largest discovered ammonite, Parapuzosia seppenradensis, and this "miniscule" human for scale (diameter is 1.8 m):
