The captions of Figs 1 to 3 were incorrectly captured as text. Please see the correct Figs 1 to 3 here.

Fig 1. Phylogenetic relationships of SANUs analyzed in this study, grouped by major clade.

Litoptern relationships are based on McGrath et al. [60, 61], with families Macraucheniidae (Ma) and Proterotheriidae (Pr) indicated. Toxodontian relationships are based on Shockey et al. [62], Bonini et al. [63], and Armella et al. [64]. Typothere relationships are based on Seoane and Cerdeño [65] and Croft and Anaya [66], with Hemihegetotherium sp. assumed to be closely related to Hemihegetotherium achataleptum. Typothere clades include Hegetotheriidae (He), Hegetotheriinae (H), Interatheriidae (Int), Mesotheriidae (Me), and Pachyrukhinae (P).

Fig 2. Metatarsal-femur ratio (Mt:F) in extinct North American ungulates and South American native ungulates.

North American ungulate data (N = 73) are from Janis and Wilhelm [28]. Data for South American native ungulates (N = 36) are provided in S1 and S2 Tables. Regression lines are ordinary least-squared regressions.

XIII, fig. 13 [78]); Diadiaphorus majusculus (Proterotheriidae), AMNH 9196 (modified from Scott 1910, pl. V, fig. 2 [78]); Theosodon lydekkeri (Macraucheniidae), AMNH 9269 (from Scott 1910, pl.

XXV, fig. 9 [79]); Scarrittia canquelensis (Leontiniidae), AMNH 29585 (from Chaffee 1952, pl. 11, fig. 2 [80]); Protypotherium australe (Interatheriidae), AMNH 9149 (from Sinclair 1909, pl. V, fig. 1 [81]); Miocochilius anomopodus (Interatheriidae), UCMP 38091 (from Stirton 1953, pl. 27 [75]); Eutypotherium lehmannnitchei (Mesotheriidae), MLP 12-1701 (reversed); Pachyrukhos moyani (Hegetotheriidae), AMNH 9481 (reversed; from Sinclair 1909, pl. X, fig. 15 [81]). Scale bars equal 5 cm in upper row (litopterns, toxodonts) and 3 cm in lower row (typotheres).
