Manuel Quiring

Very good prone calymenid trilobite from the Ordovician of Morocco with original imprint. It looks very much like a species of Colpocoryphe originally described by British paleontologist William Thornton Dean from the Montagne Noire of Southern France. Both sides of this fossil were stabilized with glue but there is no restoration done of any kind.

Species: Colpocoryphe aff. thorali Dean, 1966
Locality: Ouaoufraoute mountain, Sous-Masaa Drâa, Morocco
Geological context: Lower Fezouata formation
Age: Lower Ordovician
Size: Trilobite sagittal length is approx. 3.2cm - see also last photo with ruler in centimeters for scale.

Ordovician, Lower (485.4 - 470 million years) - Morocco

Trilobite - Positive and negative - Colpocoryphe aff. thorali
