Abstract/Notes | Quenstedt described three distinct varieties of Ammonites Davœi, with nine illustrations. They all belonged to the 7 zone of Lower Lias:—1. Ammonites Davœi, whose tubercles are somewhat clavate and with unsymmetrical prorsiradiate ribs.2. A. Davœi enodis is continental. It is a small specimen without tubercles, with fine symmetrical and prorsiradiate ribs.3. A. Davœi nodosissimus is also continental. This variety shows nine large bullate tubercles on each whorl, with close, fine, and symmetrically disposed flexiradiate ribs. |
