Acanthalomina
minuta
Trilobite
Order Lichida, Family Odontopleuridae)
Geological
Time: Silurian
Size: 6
mm long by 4 mm wide on a 37 mm by 33 mm matrix
Fossil Site:
Kopaninske Formation, Kosov, Czech Republic
Description:
Well-preserved example of a member of the Order Lichida, Family
Odontopleuridae, with dramatically-displayed spines for such a minute
taxon, a feature not often preserved intact. This one also has much
of the pustulose exoskeleton preserved as a rich white patina which
contrasts well with the dark matrix. Some examples of this diminutive
spiny trilobite have been found in Spain and the Western United
States, showing it had a more global range than many others from
the region. Trilobites from the region are becoming more difficult
to obtain as old deposits become played out or placed off-limits
by the government, making examples as fine as this even more rare.
I would recommend Milan Snajdr's excellent book to anyone interested
in the Bohemian trilobites.
