Supplementary data and codes for ammonoids morphological complexity and evolutionary rates

The "code" folder contains the code for calculating evolutionary rates and analysing the data, and the input and output data. We used the Bayesian framework implemented within the program PyRate, the per capita boundary-crosser rate, per-taxon rate, and Van Valen metric to calculate extinction and origination rates for early Pliensbachian species and Cretaceous genera datasets. The Pyrate method is implemented in python, all other methods use R code.

The "obj" folder includes 292 three-dimensional models of 146 specimens.

The "Expanded Data" file containing supplementary tables, original data, processed data and specimen tables.
