Taxonomy:

Species: Agerina quadrata (Dean, 1965)

Family: Leiostegidae

Order: Corynexochida

Class: Trilobita.


The Fezouata Shale it's a very fossiliferous area that changed the taxonomy and knowledge in general of several groups (trilobites, other Arthropods, soft-bodied creatures, Echinoderms) and helped to better understand the evolution of life.


It has been compared to the very well know Burgess Shale, at North America. In fact, it is, in late years, a prolific area in fossil discoveries that changed the fossil taxonomy of several groups of organisms and that helped to better understand the evolution of all the life on Earth. Not only several trilobite species have been newly documented there: some other Arthropods (like the famous Anomalocarids), soft-bodied creatures (like Furca sp. and others) and Echinoderms are other important groups found and studied there, among thousands of species.

********

All our trilobites were repaired after being broken at the settlement (they were glued in the lab). The vast majority don't suffer any reconstruction (=restoration) or composition. That's something we are proud to maintain as a philosophy in our work. If so, we'll tell you for sure right here.

Legally sourced and shipped from Portugal with registered tracking.

Do not hesitate to ask any questions. We will be more than happy to provide any additional details.
