The locality of Hamar-Laghdad yields a lot of well preserved trilobites with a unique red shell. Thysanopeltis are very rare, so being able to prepare this well preserved specimen was a great pleasure for me. 

The shell of trilobites found in this locality has a glass-like, fragile upper layer, which is easily damaged. Gentle sand blasting therefore is necessary. 

Fossil: Thysanopeltis speciosa austromaura (?)

Locality: Hamar Laghdad (Morocco)

Formation: Devonian

Length of the trilobite: 3.6 cm

Work required: 14 hours
