A Gallery of some of the Trilobite Order Lichida

Gallery of Lichida
last revised 25 August 2012 by S. M. Gon III

There are several stable sources of trilobite images on the web, but these are usually not arranged systematically. I have compiled just a few representative images from a variety of cited sources to share with you as a resource and a link to those other sources. I encourage you to visit those excellent sites for more information. Even the most stable websites are down temporarily. Please report persistent broken links to me.

Note: The 1997 Treatise classification convention defines Order Lichida= Superfamilies Lichoidea + Odontopleuroidea + Dameselloidea. This gallery therefore includes representatives of all three superfamilies. An alternate classification that is growing in utility separates the Odontopleuroidea + Dameselloidea into an order Odontopleurida, leaving a smaller order Lichida composed only of the Lichoidea.
