A matrix of 4,541 phenomic characters for 86 living and fossil species, combined with 27 nuclear genes, produced one parsimony tree with post-K–Pg crown-placental diversification and a reconstructed ancestral phenotype; both chronology and phenotype are model outputs rather than observations of an ancestor.
