Fig. 1 in Growth dynamics and body size evolution of South American long-necked chelid turtles: A bone histology approach

Fig. 1. Size distribution of chelid turtles represented in two different phylogenetic hypotheses from Maniel et al. (2018). Both topologies recover two alternative hypotheses (orange): the monophyly of the South American chelid clade (A) and the monophyly of the of the long necked chelid turtles (B) see Maniel et al. 2018, for more information). Grey, species smaller than 20 cm; green, 20–60 cm; blue and bold, larger than 60 cm. The size is based on the carapace length.
