Fig. 52 in Early-Middle Ordovician cephalopods from Ny Friesland, Spitsbergen - a pelagic fauna with Laurentian affinities
Fig. 52. Single most parsimonious tree resulting from constrained analysis with the "concave" interpretation plotted against stratigraphy. Stratigraphic units (in grey boxes) are Ordovician stage slices after Bergström et al. (2009), modified by Rasmussen et al. (2019). Vertical range of stage slices represents absolute age (after Rasmussen et al. 2019). Abbrevations: Tr = Tremadocian; Fl = Floian; Dp = Dapingian; Dw = Darriwilian.
