Unveiling the Secrets of Dictyoceratina - A Subgenus of Ammonites

Dictyoceratina is a subgenus of the genus Dictyoceras, which is a group of ammonite cephalopods that lived during the Late Jurassic and Early Cretaceous periods. These ammonites were characterized by their distinctive shell shapes and ornamentation, and they are found in many parts of the world, including Europe, North America, and Asia.

The Dictyoceratina subgenus includes several species of ammonites that are known for their highly evolute (coiled) shells and complex ornamentation. These species are typically found in shallow marine environments and are thought to have been active swimmers, using their mantle muscles to move through the water.

Some of the most well-known species of Dictyoceratina include D. bifaria, D. falcata, and D. radiata. These species are known for their distinctive shell shapes and patterns, which can vary depending on the location and age of the fossil.

Overall, Dictyoceratina is an important subgenus of ammonites that provides valuable information about the evolution and diversity of these fascinating ancient cephalopods.
