Paleoecology
Ammonoids are an extinct group of marine mollusks that belonged to the class Cephalopoda, characterized by their coiled and chambered shells. These creatures thrived during the Mesozoic era, particularly in the Jurassic and Cretaceous periods, and are crucial for understanding major mass extinction events due to their rapid evolutionary rates and diversity. Their fossil record provides insights into environmental changes and the impact of extinction events on marine life.
