Jebel Issoumour, Morocco
Elegant example of a bizarrely-spined member of the Acastidae this
one is a new taxon closely allied with Quadrops flexuosa. Once called
Philonyx, the genus derives its name from the unusual quadripartite
rostrum unique to this taxon. Given the distinct “shovel-nosed”
aspect of this type, it may be an entirely new genus. While most Quadrops
are known from Ofaten, this type to date has only been found in Issoumour.
Note the incredible profusion of spines displayed here. These spines
were a good defense against the fish of their day, affording quite
a mouthful for any predator with the temerity to attack. This specimen
took an INCREDIBLY LONG amount of time to prepare. Still only a small
number of specimens have been found to date at this new Issoumour
locality, despite a feverish search by the diggers.
