Acanthoscaphites is an extinct genus of cephalopod belonging to the Ammonite subclass. The average diameter of its shell was approximately three fourths of an inch, but some specimens have been found with a diameter of slightly over two inches.
Classification
Acanthoscaphites was first described by Schluter in 1872. Subsequent taxonomic revisions indicate that the relationship between Acanthoscaphites and Trachyscaphites is still unclear: Acanthoscaphites may have evolved in parallel with or as a derivative of Trachyscaphites.[1]
Species
- A. plenus
- A. tridens
- A. verneuilianus
Biogeography
Acanthoscaphites was a widespread genus during Campanian and Maastrichtian times, approximately 80 million years ago.[1] Its remains can be found in rocks of that age from Europe and North America.[2]
