A Large Ammonite, Typical of the Early Cretaceous of Madagascar, the shell is involute and compressed in the profile. Very robust ribs pass over the belly and are divided into several rows of tubercles that originally carried long thorns. Due to the poor hydrodynamics of the shell, it is assumed that the animal had a benthic life by hunting or feeding on carrion. The ammonite almost completely preserves the mother-of-pearl shell with obvious violet iridescences, and this is an important added value that greatly increases the value of this specimen.
A 100% original find, it was partially freed from rock.
