Fig. 6 in Fossil coleoid cephalopod from the Mississippian Bear Gulch Lagerstätte sheds light on early vampyropod evolution

Fig. 6 Bayesian tip-dated FBD (Fossilized Birth-Death) morphological phylogeny of neocoleoid cephalopods, showing the position of Syllipsimopodi bideni gen. et sp. nov. Numbers at nodes indicate posterior probabilities (percentage). Tips dated from the first appearance of the oldest member of the relevant lineage in the fossil record (see "Methods" and Supplementary Information). Showing geological timescale dated using Gradstein et al.2, dates in Ma and colors from International Commission on Stratigraphy; Q = Quaternary (pale yellow). Important taxa highlighted: orange = Belemnoidea, purple = Decabrachia, yellow = Prototeuthidina, green = Loligosepiina, cyan = Vampyromorphida, blue = 'teudopseid' grade, red = Octopoda. Tree does not show revised taxonomic designations: Teudopsis bollensis = Briggsiteuthis bollensis gen. et comb. nov., Teudopsis jeletzkyi = Fuchsiteuthis jeletzkyi gen. et comb. nov., Teudopsis subcostata = Suttoniteuthis subcostata gen. et comb. nov., Glyphiteuthis rhinophora = Justinianiteuthis rhinophora gen. et comb. nov., Glyphiteuthis minor = Fisheriteuthis minor gen. et comb. nov., and Trachyteuthis bacchiai = Edmunditeuthis bacchiai gen. et comb. nov.
