There are many debates over nomenclature in the paleontological world, and although our say has little to do with any decision made, I thought it would be fun to see what it would be like if we did decide such matters. Today, I ask your opinions on one of these. This is the debate over the placement of the deceased shark that goes by the species name hastilis. After a lengthy talk on a random thread (sorry mods) with @Macrophyseter I thought it would be intresting to see others view points. You have three choices, Isurus the genus in which the makos sit, long held to be the genus where hastilis belongs, Carcharodon which is the genus of the great white which is widely held to be the successor of hastilis via escheri and hubbelli, or Cosmopolitodus the proposed Genus for hastilis, planus, escheri, and a few other sharks. Be sure to explain your reasoning below. Here is a picture of hastilis and Carcharodon carcharias partially for your reference and partially to show off
As an added incentive, which ever one wins out will be on the label for hastilis in the evolution set of megalodon and the white shark I'm working on. Have fun!
