The type species
A. temnurus was formerly placed in the genus
Lepidotes, until it was moved to the new genus in 1990. Formerly placed in the
Semionotiformes, more recent morphological studies indicate that it is more closely related to extant
gar, and is in fact more closely related to gar than "true"
lepidotids such as
Lepidotes. == Paleoecology ==
