Age: Devonian
Size (25.4mm=1 inch): 23 mm long by 17 mm wide on a 53 by 64 mm matrix
Location: Djebel Issoumour, Alnif , Morocco
Code: MT264
Price: $40.00 - Sold
 Description:
A fine example of a member of the Order Proetida, Family Proetidae
with many fine details present, this one has genal spines that are
more pointed than the typical ones seen, making for an unusual opportunity
to acquire a less common example of the taxon. The most diagnostic
feature of this taxon is a granulose cephalon for which the genus
is named. The Proetidae were among the last of the trilobites to go
extinct in the Permian over 100 million years later. This is a fine
example of the type, well-positioned upon its matrix base. |
