Typhlokorynetes

Typhlokorynetes plana is a species of small, button-shaped asaphid trilobites of the family Raphiophoridae that lived during the Early Tremadocian of Vermont, United States.

The generic epithet is a compound word of the Greek words "Typhlos," meaning "blind," and "Korynetes," which means "club-bearer," in reference to the animal's eyeless state, and the glabellum that is shaped in the outline of a club or bowling pin.

[1] The specific name "plana" refers to the flattened nature of the body.

The first fossils of this trilobite were described by P. E. Raymond in 1937 as a blind proetid that he named "Warburgella" plana.

[3] Alan Shaw voiced a similar opinion when he moved it into its own genus and family, Typhlokorynetes in Typhlokorynetidae, in that it maybe a specialized styginid with unusual or aberrant sutures and hypostome anatomy.
