Description

Kolihapeltis chlupaci hollardi
Devonian
Kess Kess Formation
Morocco.

34mm spiny trilobite on 80mm matrix.

Trilobite.  Arthropod.

Kolihapeltis chlupaci hollardi is one of the rare trilobite species from Morocco.  The genus, Kolihapeltis, is known from the Early to Middle Devonian of Europe and North Africa.

The Devonian turned out to be the time of the last major radiation of trilobites.  The end-Devonian mass extinction event nearly wiped them out, reducing them to smaller sizes and less conspicuous roles in ecosystems until their final extinction at the end of the Permian.
