Lachnostoma latucelsum

Trilobites Order Asaphida Suborder Asaphina Superfamily Asaphoidea, Family Asaphidae
Geologic Age: Middle Ordovician
Trilobite is 24 mm long
Ninemile Shale, Eureka County, Nevada
Remark: This trilobite shows the typical effacement, or loss of detail, to the exoskeleton seen in many asaphids. The flattened leading edge of the cephalon and trailing edge of the pygidium may helped keep the trilobite at the surface of a silty seafloor.
