Figure 15 in Neurocranial bones are key to untangling the sea cow evolutionary tree: osteology of the skull of Sobrarbesiren cardieli (Mammalia: Pan-Sirenia)

Figure 15. Phylogenetic relationships of Pan-Sirenia, after updating and reanalysing the dataset of Velez-Juarbe & Wood (2018). A, consensus tree of the 7560 most parsimonious trees (MPTs) with equally weighted characters (length = 310 steps; consistency index = 0.442; retention index = 0.777; rescaled consistency index = 0.344). B, consensus tree of the 945 MPTs under implied weighting analysis (concavity constant, k = 12; fit = 10.75914; consistency index = 0.442; retention index = 0.777; rescaled consistency index = 0.344). Numbers above branches represent the Bremer index, with values below two not represented. Numbers below branches represent bootstrap values> 50, after 1000 replications. Clade names and definitions follow Velez-Juarbe & Wood (2018).
