Ammagnostus laiwuensis

Weeks Formation

Millard County, UT
Cambrian

 

 

Here is an uncommon agnostid, Ammagnostus laiwuensis, from the Weeks Formation. The agnostids are not very well recognized and understood from the Weeks Formation and they are very rarely found. This nice specimen measures 1/4" long. This specimen is found in a different location as you can tell by the black limestone.
