Although previously placed in the
paraphyleticfamily Palaeoniscidae,[1]Turseodus was later referred to its own family,
Turseoidae, by
Wilhelm Bock.[5] The
lachrymal bone of Turseodus forms part of the oral margin, an unusual condition known otherwise only from the
Early to
Middle TriassicPteronisculus. Based on this
synapomorphy and other similarities, a close relationship between Turseodus and Pteronisculus is hypothesized.[6] There are also similarities with Turfania from the
Permian of
China.[6] However, a close evolutionary relationship between these genera has not yet been tested by
cladistic analyses.
