Elrathia Trilobites Mass Mortality from Wheeler Formation

Description: This is a mass mortality plate that I recovered and prepared from the Wheeler Formation numerous Elrathia kingii trilobites of various sizes. There are 12
Elrathia. Three are enrolled and one is a ventral view; there are also a few partials.
If you've hunted trilobites in Utah, you'll now such finds are an uncommon occurence. The Wheeler Formation also yields Burgess Sahle like soft bodied animals, though not in abundance, and almost never in trilobite layers; most collectors can't even recognize them.
