Description

Nostoceras is the fossil of an extinct cephalopod mollusk in the class of Ammonidea.
The name comes from the Greek "nostos" that means return, and "ceros" meaning horn, because of the shape of the shell, whose syphonal chamber returns to the spiral.
Its presence on earth occurs in the Campanian age (upper Cretaceous) so it's between 72 and 83 mya.
This beautiful collectors piece shows two specimen on their original matrix, and the well defined syphonal chambers has been left connected to the spiral in order to not compromise the solidity of the piece.
