description Overview

Cryptolithus

Cryptolithus is an extinct genus of trinucleid trilobite that lived during the Ordovician period. It is distinguished by its broad, perforated cephalic fringe, which extends outward from the head and is commonly referred to as a "lace collar." The genus was entirely blind, lacking compound eyes. Fossils of Cryptolithus are prevalent in marine sedimentary deposits across North America and Europe.

Primaspis
