Figure 7 in Diegoaelurus, a new machaeroidine (Oxyaenidae) from the Santiago Formation (late Uintan) of southern California and the relationships of Machaeroidinae, the oldest group of sabertooth mammals

Figure 7 Temporally calibrated machaeroidine phylogeny. Topology of sampled taxa as in Fig. 5 Temporal positions of additional machaeroidines, including Isphanatherium ferganensis and taxa in open nomenclature, are shown. Biochronological assignments follow Gazin (1976), Dawson et al. (1986), Walsh (1996), Averianov & Godinot (2005), Gunnell et al. (2009), Zack (2019a), Zack (2019b), and Tomiya et al. (2021). Temporal assignment of biochrons follows Tsukui & Clyde (2012), Chew & Oheim (2013), Murphey et al. (2018), Wang et al. (2019), and Tomiya et al. (2021). Full-size DOI: 10.7717/peerj.13032/fig-7
