Figure 10. Length-versus-age growth curves constructed for multiple species of fossil crocodylians, after Figure 2a in Erickson and Brochu (1999), including two representatives from the genus Deinosuchus. For comparison, the growth curve of the American alligator (Alligator mississippiensis) is shown. American alligator growth curve obtained from a catch-tag-and-release study (Chabreck and Joanen, 1979) of thousands of individuals from Louisiana, USA.

Length-versus-age data (light blue dots) inferred from Otodus megalodon teeth and vertebrae, as well as the extrapolated growth curve (dashed line), after Figure 2a in Shimada (2021). The specimen from which the vertebrae data were obtained had not yet matured, even though it is estimated to have been 46 years old at time of death. The great white shark growth curve of Wintner and Cliff (1999) is included for comparison. Shark image credit: Mostafa Elturkey. Wikimedia Commons, public domain.
