Some Special Morphological
Terms
last revised 01 July 2007 by S. M. Gon III
In addition to the standard terms for the typical dorsal morphology of trilobites,
there are some terms that are used to describe features that are specific
to certain orders and/or suborders. Often, these are terms used because of
distinguishing variations in form. For example, the glabellar lobes of Lichida
do not show simple lateral furrows and lobes, but are typically fused into central
and lateral lobes. Below are some examples of special terms applied
to certain trilobite groups. Click on each image for more information on that group.
