Phylloceras – Fossil Ammonite on a wooden base from Madagascar, weighing 1259 g with dimensions 200 × 135 × 55 mm.
Description from the seller
This specimen belongs to the genus Phylloceras, an elegant and ancient ammonite from the Mesozoic era. Its shape is immediately recognizable: a highly involute spiral, in which the last whorl almost completely envelops the previous ones, leaving a tiny umbilicus and a full, harmonious profile. It is the signature of the Phylloceratidae, ammonites that traversed the Mesozoic with refined and surprisingly stable morphology. The surface has been polished, revealing a natural mineralization: a network of orange-honey dendrites branching across the shell, following old fractures, pores, and microchannels formed during fossilization. It is a spontaneous pattern, impossible to replicate, making each specimen unique. The warm hue, typical of the Cretaceous layers of Madagascar, complements the rounded and full shape of the shell. The fossil is mounted on a solid wood base, chosen to provide stability while allowing visual space for the spiral.
