Silurian Odontopleurid Trilobite Acanthalomina minuta

Acanthalomina minuta

Class Trilobita; Trilobite Order Odontopleurida, (or Order Lichida if you prefer), Superfamily Odontopleuroidea, Family Odontopleuridae

Geological Time: Silurian

Size: 6 mm long by 4 mm wide on 37 by 33 mm matrix

Fossil Site: Kopaninske Formation, Kosov, Czech Republic

Acanthalomina minuta This is a superbly preserved example of a member of the Order Lichida, Family Odontopleuridae, with dramatically displayed spines for such a minute trilobite, a feature not often preserved in the species. This specimen also retains much of the pustulose exoskeleton preserved as a rich white patina that contrasts well with the dark matrix. Some examples of this diminutive spiny trilobite have been found both in Spain and the Western United States, showing it had a more global range than many Bohemian trilobite genera.
