Description
Tetragonites epigonum Fossil Ammonite – Turonian, Cretaceous – Madagascar
About the Fossil:
This exceptionally preserved Tetragonites epigonum ammonite fossil originates from the Turonian stage of the Late Cretaceous (~93-89 million years ago) and was discovered in Madagascar. Tetragonites is a genus of evolute, compressed ammonites, known for their relatively smooth, weakly ribbed shells and distinctive flattened whorls, making them a fascinating species for study and collection.
During the Late Cretaceous, ammonites like Tetragonites epigonum thrived in tropical marine environments, where they served as important members of the food chain. Their streamlined shell design suggests they may have been efficient swimmers, capable of both vertical and horizontal movement in the ocean. The Turonian-aged deposits of Madagascar are world-renowned for producing some of the finest ammonite specimens, offering insight into the rich biodiversity of the Cretaceous seas.
