With the exception of certain pyritized ammonites from a few horizons, notably the Tropidoceratids discussed below, the specimens from the Belemnite Marls are not in a good state of preservation. Some, like the Polymorphites of the lineatus type, from Bed 112, or Phricodoceras ...

The Ammonites of the Green Ammonite Beds of Dorset
Quarterly Journal of the Geological Society of London, 1936I. Introduction. As on previous occasions when I have had the privilege of examining the ammonites of the Lower Lias of Charmouth, collected by Dr. W. D. Lang, I propose to discuss the identifications, given in his stratigraphical account; also to comment on the generic classification and the phylogenetic relationships of the ...

Centered on the region around the modern city of Amman, Jordan, the tribally organized, agropastoralist society of the Ammonites (literally, "the sons of Ammon") flourished during the Iron Age II (ca. 1000–500 BCE), and especially in the latter half of this period.

Ammonites are externally shelled cephalopods and range in geologic age from the Devonian to the Late Cretaceous. They comprise nine orders that may be informally grouped into the paleo-, meso-, and neoammonoidea. The paleoammonoidea consists of the Devonian-Permian goniatites, anarcestids, clymeniids, and prolecanitids.
