Fossil record
The fossil record of this genus dates back to the Cretaceous[1] (age range: from 112.6 to 99.7million years ago). Fossils of species within this genus have been found in Egypt, France, Madagascar, South Africa and United States (California). These cephalopods were fast-moving nektonic carnivores.[2]
