I recently received a 40 lb box of U‐dig shale and I was mostly done splitting it when I found this (this is the largest Peronopsis interstricta that I found in the shale I received). Ps. The ruler is in inches.
While small, I'm still excited about finally picking up my first trilobites! Elrathia kingi and Peronopsis interstricta, both from the Wheeler Formation. The free cheeks on the baby kingi are very well preserved, hence why I choose him over some of the larger but more poorly preserved ones. On a side note, I just read on Wikipedia that Peronopsis interstricta was reclassified as Itagnostus interstrictus. Are they correct? I can't seem to find a reference to this anywhere respectable.
