Ventral Triarthrus with Pyritized Legs and Antennae

Name: Triarthrus eatoni

Age:  Upper Ordovician

Formation:  Lorraine Group, Whetstone Gulf Formation

Location:  Lewis County, New York

Size: Trilobite is over 1 centimeter long

Price: SOLD

Specimen SSA826

This is the type of trilobite that every collector dreams about! It is a beautiful Triarthrus eatoni from the Lorraine Group, Whetstone Gulf Formation of upstate New York. The ventral trilobite was prepared slowly, hoping against hope to expose some soft parts of the trilobite. Although only one in hundreds(?) of trilobites have traces of soft parts preserved, this specimen hit the jackpot! BOTH antennae and two very distinct rows of appendages are exposed - these are VERY EASILY seen in the photos and with the naked eye. There have been very few trilobites ever found in the fossil record with this much detail of the delicate soft parts. This is a very collectible example of a trilobite displaying its rarely-seen antennae and appendages. (Specimen was immersed in toluene to heighten contrast)
