description Serratolamna serrata Overview
Serratolamna serrata is an extinct lamniform shark known primarily from fossil teeth. Louis Agassiz described the species in 1843, and fossil references place it in the family Serratolamnidae. Its record extends into Upper Cretaceous deposits, including Maastrichtian material, and the teeth can show lateral cusplets that help distinguish them from some related lamniform sharks. The species is relevant to paleontologists studying Cretaceous marine ecosystems and fossil elasmobranch taxonomy.
