Nesonektris

''Nesonektris aldridgei'' is an extinct deuterostome chordate from the Late Botomian-aged Emu Bay Shale Lagerstätte in Kangaroo Island, Australia. So far, it is the fourth described vetulicolian that is not restricted to the Maotianshan Shales (the other three being ''Ooedigera'' of Sirius Passet, ''Banffia'' of the Burgess Shale, and ''Skeemella'' of the Wheeler Shale).
==Anatomy==
''N. aldridgei'' is known from several incomplete fossils which suggest that, in life, it was a fairly large animal (when compared to other vetulicolians). The largest fossil is about 150 millimetres long, leading researchers to estimate that that individual was about 170 millimetres long. The exquisitely preserved fossils show that running the length inside the tail was a notochord, thereby demonstrating the animal's chordate affinities as being related to tunicates. The forebody, and overall form are similar to vetulicolids of Vetulicolidae, though, its researchers do not have confidence to place ''N. aldridgei'' within Vetulicolidae, or any other family within the vetulicolian class Vetulicolida.
