Lytoceratida

Crioceratites duvalii, copyright Hectonichus.

Belongs within: Ammonoidea.

The Lytoceratida are a lineage of ammonites known from the Jurassic and Cretaceous.

Characters (from Enseger & Keupp 2002): Conch thin-walled, usually weakly sculptured. Suture line with primary sutural formula ELU2U1I; suture elements microphyll (strongly slit). Siphuncle usually reaching marginal position after one whorl; septal necks becoming prochoanitic at very early ontogenetic stage.

Leptoceras is a genus of small, loosely coiled ammonites known from the Lower Cretaceous ((Upper Berriasian to Valanginian) (Wright et al. 1996). Wiedmann (1969) depicted this genus as ancestral to a number of later ammonite lineages, including both heteromorphic and regular forms.

Characters (from Wright et al. 1996): Rather evolute, with whorl section depressed and subcircular, oval, polygonal, or subquadrate; ribs strong, generally straight, continuous over rounded or flat but not concave venter; on early whorls at least umbilical, ventrolateral, siphonal, and, in most specimens, midlateral tubercles; in multituberculate forms umbilical tubercle more prominent than midlateral; tubercles may disappear with age and may or may not be rejuvenated on last part of shell. Marked dimorphism in size apparently general.

Ancyloceratidae

Australiceras sp., in the Houston Museum of Natural Science.

Belongs within: Aptychophora.

The Ancyloceratidae are a group of ammonites known from the Lower Cretaceous. They are commonly heteromorphic, though some derived forms reverted to a more standard tight coil.

Characters (from Wright et al. 1996): Either coiled in a loose or tight, more or less equiangular spiral (criocone) or with an initial spire followed by curved or straight shaft and terminal hook (ancyloceratoid); sometimes with phylogenetic tendency to tighter, normal ammonitic coiling. Whorl section ranging from circular to square or polygonal; tending to develop strong, periodic ribs with umbilical, lateral, and ventrolateral spines, separated by few to many, fine, untuberculate ribs. Ornament rarely constant through growth. Probably strongly dimorphic throughout, but presumed microconchs rarely matched with macroconchs. Sutures florid, with trifid lobes or simplifying.

Marathonitidae

Peritrochia, from here.

Belongs within: Ammonoidea.

The Marathonitidae are a group of more or less globular ammonoids known from the Upper Carboniferous to the Upper Permian (Miller et al. 1957).

Characters (from Miller et al. 1957, as Marathonitinae): Conch subglobular to globular. Lateral lobes of sutures tending to be trifid.
