Figure 2 in Parallel evolution in molar outline of murine rodents: the case of the extinct Malpaisomys insularis (Eastern Canary Islands)

Figure 2. Schematic representation of the modern and fossil murine rodents compared to Malpaisomys. Top, molecular phylogeny after Chevret (1994) and Chevret et al. (2001). A calibration of the time of divergence between taxa is given by reference to the divergence of the Rattus rattus lineage, estimated as having occurred 12 Mya (Chevret et al., 2001). The grey box includes the arvicanthine rodents, characterized by a herbivorous diet. Bottom, fossil lineages with investigated localities. Thick grey lines indicate taxa with stephanodont characteristics, thick black lines, complete stephanodonty. Crosses indicate extinct taxa.
