FIGURE 6. Patterns of taxonomic diversity and dietary diversity of NALK metatherians. Top: Known taxonomic diversity (gray squares and line) of NALK metatherians and the metatherian diversity sampled in this study (black circles and line). Middle: Dietary diversity of NALK metatherians through time (out of six dietary categories). Judithian diversity count is based on our DFA classification of Iugomortiferum thoringtoni as a carnivore. Bottom: Hypothesized phylogenetic relationships of NALK metatherians sampled in this study (the deltatheriid Atokatheridium boreni was removed). The phylogeny is modified from Williamson et al. (2014), Wilson et al. (2016), and Cohen et al. (2020). Thick horizontal bars represent the known temporal range of each species. Bar colors represent the dietary categories assigned to each taxon in this study. For cases in which specimens of the same species were classified differently, we include both classifications in this figure, with the exception of Iugomortiferum thoringtoni and Didelphodon vorax. Our DFA classification for Iugomortiferum thoringtoni (carn) contradicts additional lines of evidence that suggests it is a plant-dominated omnivore (see Discussion), and thus we classify it here as 'carn/pdo.' Our DFA classifies the two Didelphodon vorax specimens as an animal-dominated omnivore and an invertivore, but additional lines of evidence suggest that it is an animal-dominated omnivore (see Discussion). Abbreviations for diet categories: ado = animaldominated omnivore; carn = carnivore; frug = frugivore; inv = invertivore; pdo = plant-dominated omnivore; sis = softinvertebrate specialist. Abbreviations for NALMAs: Aquil = Aquilan; La = Lancian.
