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
