Mid Devonian, Eifelian
This is an un described Gerastos from the Prgaian of Jorf and it exhibits many differences from the specimens later in the Devonian of Morocco. The specimen is in really good condition and has a lovely patina. Specimens from Jorf are extremely hard to prepare and many hours of work has gone into exposing this specimen.
The specimen measures 2.3cm's (matrix more)
