(a) Von Mises stress mesh-weighted arithmetic means (MWAM) calculated for anterior (Ant.), lateral (Lat.), and posterior (Post.) teeth of the five analysed otodontid species, simulating puncture and draw scenarios with scaled force magnitude. Data are shown in a temporal context (in million years ago, Mya) where stratigraphic range of each taxa is represented by grey bars (stratigraphic ranges based on Cappetta1 and Diedrich9). (b) Density distributions of coefficients and p values derived from correlation analyses between von Mises stress MWAM and species age (randomly selected within their chronostratigraphic range, n = 10,000). Epoch: Pa, Paleocene; Eo, Eocene; Ol, Oligocene; Mi, Miocene; Pl, Pliocene; Age: Da, Danian; Se, Selandian; Th, Thanetian; Yp, Ypresian; Lu, Lutetian; Ba, Bartonian; Pr, Priabonian; Ru, Rupelian; Ch, Chattian; Aq, Aquitanian; Bu, Burdigalian; La, Langhian; Sv, Serravalian; To, Tortonian; Me, Messinian; Za, Zanclean; Pi, Piacenzian.
