Fossil Museum Trilobites Pair
Suborder Phacopina, Superfamily Acastoidea, Family Acastidae
Time: Lower Devonian, Pragian Stage
are 65 mm long by 23 mm wide and 42 mm long by 20 mm wide (curve measure
including rostrum) on a 115 mm by 100 mm matrix
Unusual examples of a member of the Order Phacopida, with many fine
details present. It looks for all the world to be related to that
famous prevaricating puppet Pinocchio after telling a spate of whoppers.
Just discovered in 2013, researcher in Spain after studying the
taxon assigned it a name in mid-2014. It looks to have affinities
with Morocconites, but the rostrum here is far, far more elongated.
The first example I was aware of consisted solely of the cephalon
with an attached rostrum, indicating it was not some fanciful composite
specimen. Subsequently a few came to light as a mad dash by diggers
to the site ensued. Most of the literal handful come from Jebel
Iazzi or Jebel Issoumour. Those sites were played out very quickly.
Now a new location Ihourane near Boulashghal, Morocco has been found.
To my knowledge this is the first from this location offered. Other
than a few small patches of missing exoskeleton these are quite
complete. The preparator has chosen to leave them unrerstored. They
can be seen as a brownish color.
