A couple Maquoketa trilobites I'm unsure of


Recommended Posts

Here are two bugs not in great shape from the Elgin Member of the Maquoketa Formation (Upper Ordovician) of Minnesota. I am leaning towards Flexicalymene sp. for the first and guessing Isotelus or Anataphrus for the second. Any thoughts are appreciated.

I think you have it right. Anataphrus seems the right call for the second trilobite.
