Macrocephalitidae [SEP] parent taxon
Macrocephalitidae
Macrocephalitidae is an extinct family of marine invertebrate animals belonging to the superfamily Stephanoceratoidea, order ammonite.
Etymology.
The Macrocephalitidae is one of the 11 families listed in the Treatise, 1957 Part L in the superfamily Stephanoceratoidea.
According to Donovan et al. (1981) the superfamily Stephanoceratoidea should contain only five families and the Macrocephalitidae of the Treatise are reduced to subfamilies within the Sphaeroceratidae, Macrocephalitinae and Mayaitinae, but still in the Stephanoceratoidea.
Genus.
- "Macrocephalites" †
- "Pleurocephalites
The Stephanoceratidae gave rise to the Thamboceratidae which in turn gave rise to the Clydoniceratidae. The Sphaeroceratidae gave rise to the Tulitidae which is the source for both the Macrocephalitidae and the Pachyceratidae. The Pachyceratidae lead to the Mayitidae, the Macrocephalitidae both the Kosmoceratidae and Cardioceratidae.
