Introduction The extinct megatooth shark Carcharocles megalodon is the largest shark ever to exist Gottfried et al. Open in a separate window. Figure 1. Figure 2.

Geological Age Assessment For each specimen studied, we examined the accompanying label and used collection databases to verify the age assignment. General Statistical Comparisons In order to assess C. Geographic Statistical Comparisons In order to assess how trends in body size of C. Supplementary Analyses Megatooth sharks have diagnathic heterodonty i. Figure 3. Table 1 Descriptive statistics of Carcharocles megalodon body size m through time.

Evolution Evolutionary Body-Size Mode [H1: Carcharocles megalodon increased in size through time, reaching its largest size prior to extinction]. Figure 5. Table 3 Model-fitting results for Carcharocles megalodon body size trends. Broader Implications To our knowledge, body-size trends of large predatory sharks have never been studied before over geologic time.

Our results have three broader implications that provide a deep-time perspective to the understanding of the body-size trends of marine apex predators: 1. Conclusions We found that Carcharocles megalodon body size had a left-skewed distribution and was significantly different between hemispheres and ocean basins through geologic time.
