Figure 10 in Evolutionary relationships and systematics of Atoposauridae (Crocodylomorpha: Neosuchia): implications for the rise of Eusuchia

Figure 10. Time-scaled phylogeny showing the relationships of Atoposauridae to the other taxa analysed in the present study (based on the topology provided in Fig. 5A). Atoposauridae is marked with a red star. Created using the strap package (Bell & Lloyd, 2015), using the geoscalePhylo() function and an 'equal' time-scaling method.
