Analysing Trophic Competition in †Otodus megalodon and Carcharodon carcharias through 2D-SEM Dental Microwear

Abstract

Boessenecker et al., 2019). Considering the significant role that modern sharks play in regulating prey communities and ecosystem structure (Ferretti et al., 2010), its extinction likely had a profound impact on the functioning of the ecosystem and the dynamics of the trophic web within ancient marine communities (see Pimiento & Clements, 2014; Cooper et al., 2022). Conventionally, it has been hypothesised that † O. megalodon was constrained to warm temperatures,
