A type of formerly extinct marine Terragen cephalopod mollusk, distinguished by an elaborately coiled and chambered shell.

The chambers of ammonite shells display intricately shaped septa and sutures. There were tens of thousands of known and estimated species, which were widely distributed during the middle and late Paleozoic and the Mesozoic eras. At least two thousand real and fake species have been lazurogened since the start of the First Federation.

Ammonites are classified in the phylum Mollusca, class Cephalopoda, subclass Ammonoidea. With the notable exception of a number of bioborged and biochipped pet clades of the Psyke Genesis Superbrights of the Rho Ophiuchi Complex, ammonites have not been provolved; their brains are less developed than those of coleoid molluscs, and many suffer from faulty genome templates (stemming from poor lazurogenics by a number of amateur mesozoic enthusiasts) making them somewhat difficult to work with.
