Truly unusual, half mineral, half fossil. A rare silicified belemnite with pyritised end.
Golden and shiny pyrite aggregates with belemnite ridges - a new discovery from a river bed in the Caucasus.
The Belemnite was replaced by flint, while the rotten meat of squids provided the necessary sulphur which, combined in a ferrous environment, allowed the formation of pyrite crystals.
A fascinating and extraordinary specimen.
High-quality pyrite, much more saturated and bright than it looks in photos.
The tip was repaired but with this type of fossil is impossible to remove it from the matrix without splitting it.
Dimensions: 73 x 42 x 35 mm.
Weight: 112 g.
Origin: Karachay Cherkessia, Russia.
