The Phylogenetic Affinites of Nothofagus (Nothofagaceae) Leaf Fossils Based on Combined Molecular and Morphological Data
journal contribution
posted on 2023-05-16, 11:54 authored by Gregory JordanGregory Jordan, Robert HillRobert HillThe phylogenetic placements of leaf fossils of Nothofagus (Nothofagaceae) were determined using parsimony analyses of molecular and morphological data for extant species combined with morphological data for fossils. Placement was possible for only seven of the 30 or so described fossil species of Nothofagus because only these had sufficiently good preservation of both cuticular and leaf architectural characters. In combined analyses of morphology and molecular data, leaf cuticular characters showed little homoplasy. In contrast, many architectural characters, including some leaf margin and venation characters, showed high homoplasy, making it difficult or impossible to accurately determine the phylogenetic affinities of impression fossils of this genus.
