Figure 2 in Stingray diversification across the end-Cretaceous extinctions

Figure 2. Molecular phylogeny of elasmobranchs, with emphasis on stingrays (Myliobatiformes), based on undated (clock-free) analysis of the nuclear and mitochondrial data (excluding third codons). Numbers at nodes are posterior probabilities; branch lengths proportional to inferred divergence (see scale). The rooting could be anywhere along the arrowed branch (tree here is arbitrarily rooted at left end of this branch). For full details of specimen numbers, see table S1.
