Tomagnostella exsculpta

Weeks Formation

Millard County, UT
Cambrian

 

Here is a very uncommon agnostid, Tomagnostella exsculpta, from the Weeks Formation. The agnostids are not very well recognized and understood from the Weeks Formation and they are very rarely found. This outstanding specimen measures 1/4" long. There is another partial agnostid on the same plate.
