Suture patterned ammonite probably phylloceras 160 grams
Species
Description
Shells of Phylloceras can reach a diameter of about 8–10 centimetres (3.1–3.9 in), with a maximun of about 20 centimetres (7.9 in). Thes primitive ammonites had an involute, laterally flattened shell with a regular shell opening. They were almost smooth and the ornamentation was virtually absent or, at most, represented by simple growth lines barely visible. The striking sinuous suture lines were characteristic of this genus. They are reminiscent, in some ways, of the leaves of plants (hence the name Phylloceras, which means " leaf-horn").
Distribution
Fossils of species within this genus have been found all over the world, particularly in Western Europe.
