A couple of rough trilobites for ID

Recommended Posts

I am down to my last  few trilobites to label from this summer yet. Am open to suggestions on these less than perfect finds:

 

1. Found in the Galena/ Ordovician of Iowa. Isotelus? If so, is the species obvious?DSC_0893-001.JPG.40ab71a873128b9fb7c538fb7d552eb7.JPG 

 

 2. Found in the Platteville formation/ Ordovician of SW Wisconsin. Flexi?

3. Another Galena/ Ordovician but from Minnesota

First one is an Isotelus, but cant tell the species. The second one looks like a Flex, but again species I cant tell. The 3rd one looks like a Anataphrus borraeus.

Actually no. I've seen them in a Demott and Slocom report. Theres two on my list. One is from the Maquoketa formation and the other is from the Platteville. I never even considered it as a possibility. I will have to sit down sometime soon and look at the morphology between the two. Piranha has one heck of an eye...lol.
