FIGURE 6 in Histology of spinosaurid dinosaur teeth from the Albian-Cenomanian of Morocco: Implications for tooth replacement and ecology

FIGURE 6. (A) Natural logarithm of tooth formation rate plotted against the natural logarithm of the body mass. Dark blue = sauropodomorpha, light blue = sauropods, purple = ornithischians, green = theropods. (B) Natural logarithm of known tooth replacement rates plotted against natural logarithm of tooth formation rates including all available archosaurs, with a regression line and the regression equation. Colour code as above; yellow = spinosaur with the standard deviation as error bars. (C) Natural logarithm of known tooth replacement rates plotted against natural logarithm of tooth formation rates including theropods only, with a regression line and the regression equation.
