Origin, evolution and systematics of the dwarf acanthoceratid Protacanthoceras Spath, (Cretaceous Ammonoidea) Vol Page 65 Ashgill Brachiopoda from . Abstract. Paleontologists have long recognized that the fossil record seems to indicate a strong relationship between ontogeny and phylogeny. Any attempt to assess the nature of this relationship, however, is plagued by many problems, not the least of which are the dual specters of Ernst Haeckel and Walter Garstang, which have long haunted by: The shell of an ammonoid is a kind of autobiography of the animal that once occupied it. Different parts of the shell tell different parts of the life history. The growth lines and the tiny intervals Cited by: Towards a model for speciation in ammonoids.

Relying on the latest analytical techniques, this all-embracing new reference offers comprehensive coverage of the development, evolution, and morphology of both fossil and living cephalopods. In 34 in-depth chapters a group of 51 international neontologists and peleontologists offer and opverview of current methods, data, analyses, and. Versandbuchhandel.

Mantle length (ML) is the standard size measure for coleoid cephalopods (shell diameter being more common for nautiluses) and is almost universally reported in the scientific mantle is the cephalopod's "body", lying posterior to the head and enclosing the visceral mass and mantle cavity, the latter being used for locomotion by jet propulsion.
