Spinodontochile aff spinifer
Trilobites Order Phacopida, Family Dalmanitidae
Geological Time: Lower Devonian
Size: Trilobite fossil is 75 mm long
Fossil Site: Jebel Issoumour, Alnif, Morocco
 Description:
A elegant example of a member of the Order Phacopida, Family Dalmanitidae
with many fine details present. While this one is similar to the trilobite
Zilchovaspis rgosa, often termed Odontochile, it is a different genus.
Where Zilchovaspis displays rugosities (bumps) on the thorax, this
one has more pronounced ones. Indeed , the describer chose to make
this distinction by using spine in both the genus as species names
of this dramatic taxon. It is only the third I have been able to secure.
The spines are truncated, rendering this a most affordable example
of this unusual taxon. |
