Rare red Phacopid - Barrandeops cf. granulops - 5 cm

Descrizione
Rare red Phacopid - Barrandeops cf. granulops - 5 cm
Lower Devonian, Emsian Stage - Morocco, Hamar Laghdad

These red trilobites are restricted to Hamar Laghdad. The red color is explained by silicification of the exoskeleton with a combined enrichment in iron. The red trilobites come in varying inensities of red - sometimes bicolored with a grey of a blueish to greenish tint. This might be explained by partial silicification, while other parts remain calcitic- a feature original researched in a red Phacopid with greenish eyes (the blue-green color is induced by elevated iron - manganese contents).
The color of this specimen changes more into a violet tint, the matrix is greyish. This shows how variable the color of this deposit is, depending on the chemistry.


The Barrandeops measures 5 cm in length along the body and weighs 186 g, including the matrix obviously.
The complete object measures 8 x 6,5 x 4,5 cm in its widest dimensions.

The Trilobite will be shipped from Germany as insured Priority Mail via Deutsche Post. It can of course be collected if preferred.
It comes with an ID card and invoice (incl. VAT).
