Trilobite ID request

Recommended Posts

Good morning folks.  I have just received a Trilobite from the Silurian Period of Kankakee, Illinois.  It has not been identified by the seller and I'm wondering if someone here might know what species this is.

I agree with dalmanitid, but I'll need to check my sources later on today to suss out which one. I know there was a newly erected genus (Glyptambon) in that area. I'm not saying it is that one, or Dalmanites, but we can keep those possibilities open for now. :)

Thanks Kane!!!  I'll be checking on and off today (company coming) to see if your research provides anything different.

The Cephalon looks like it would belong to a Dalmanites, or Odontochile.

Thanks fossilcrazy!!  My research hasn't done much so far.

For now, have a look at this somewhat dated article: https://archive.org/details/newdevoniantrilo64roys

 

 

The Devonian is absent in Kankakee so your first suggestion is correct.  An internal cast of Glyptambon verrucosus.
