2 Geology of the area to the east of Emu Bay on the NE coast of Kangaroo Island, South Australia, showing the extent of the Emu Bay Shale at Big Gully, including the location of the main Konservat-Lagerstätte sites on the shoreline and at Buck Quarry (after Gehling et al. 2011).

(a) Reconstruction of Nesonektris aldridgei; by Katrina Kenny. (b) Axial rod structure of N. aldridgei (SAM P46336a) interpreted as a putative notochord, with arrows showing offset blocks. (c) Phylogenetic position of vetulicolians within Deuterostomia, based on the analysis by García-Bellido et al. (2014); parsimony-bootstrap values (above branches) and Bremer support (below) are shown for analyses including/excluding the non-vetulicolian fossil taxa. John R. Paterson et al.
