Products description


Here is a  nice and prone "Morocco - Trilobite" of the species  Gerastos  tuberculatus.

The recently established sub species  Gerastos tuberculatus marocensis is discriped from the Maider - Basin  and from the  Jebel Zguilma.  In 2005 Stacey Gibb describes this new subspecies in her publication of her master degree thesis. However  in the “Zguilma Paper” (Chatterton et al  2006) is this subspecies also mention as nsp. Presumably, there was overlap in the review and publication of both work.
How ever it is not complatly clear if this trilobite is to account to subspecies  Gerastos tuberculatus marocensis Gibb, 2005. Aditonaly it is unlikyly that there is only one subspecies of   Gerastos tuberculatus in Morocco.
