Order Harpetida, Family Harpetidae Formerly Aristoharpes
Time: Middle Devonian
is 40 mm long
Elegant example of a member of the newly-erected (2002) Order
with many fine details present. Previously, this one was known
as Aristoharpes (taxonomy of trilobites seems to be perpetually
state of flux). Notice the fine pitting of the preglabellar ring.
This one was well able to stay at the surface of the seafloor
of the dramatically curving “shield”. It has been prepared
to allow for easy viewing of the body which is partially enrolled.
The dramatic cephalic shield has been prepared freestanding, showing
this fine example to best advantage.
