Exceptional fossils from Peru and an integrative phylogeny reconcile the evolutionary timing and mode of Gavialis and its kin

The acquisition of a long and slender snout (longirostry) resulted in extreme similar morphology across crocodylians and, therefore, raised a conflict between morphological and molecular phylogenetic hypotheses involving the longirostrine living gharials, Gavialis gangeticus and Tomistoma schlegelii. This discrepancy is not only topological but also concerns divergence time estimates for the crown clade Gavialidae, especially due to the inclusion of another longirostrine forms, ancient ‘thoracosaurs’—which introduces significant chronostratigraphic inconsistencies. To contribute to reconcile these contrasting lines of evidence, exceptionally preserved fossils of a new Miocene gavialid from Peru were included in a total-evidence Bayesian analysis. Our analysis integrates morphological, molecular, and chronostratigraphic data and incorporates most taxa of the largest adaptive radiation of gavialids, which occurred in the Cenozoic of South American and Caribbean (SAC).

## Description of the data and file structure

This is a zipped file containing:

* (SF1) The morphological matrix in nexus format.
* (SF2) The molecular matrix in nexus format.
* (SF3) The executable BEAST file. The BEAST file was written for BEAST v.2.7.6.
* (SF4) The final annotated tree.
* (SF5) The R code to plot the tree using the *strap* package.
* (SF6) The final .log file (used in the R code).
