Title Data matrix used for the analysis
Downloaded 18 times
Description This data matrix is based upon a modified version of the data matrix of Lecuona (2013), which in turn, was modified from the analysis of Nesbitt (2011). The changes proposed by Butler et al. (2014) were also in this data matrix (also Lecuona et al. unpub. data). Finally, we added the early crocodylomorph Carnufex carolinensis (Zanno et al. 2015, Drymala and Zanno 2016), modified scorings for several taxa, and modified the formulation of the characters 219 and 241. Three terminals were included for Trialestes, the holotype (PVL 2561), the referred specimen (PVL 3889), and the combination of both. The final data matrix consists on 87 terminals and 483 characters.
