Plicatodus fossils generally only consist of scattered, isolated teeth, with one exception: a partial skeleton that includes the head, dorsal spine, and
pectoral girdle.
Species The type species for this genus,
P. jordani was described in 1995 from Permian-aged material (the
Asselian part of the
Cisuralian to be specific) found in the upper
Odernheim Formation of the Saar–Nahe Basin: a
molasse of freshwater and shallow marine deposits from late
Carboniferous to the early
Permian Periods.
P. plicatus was originally described as a member of the genus
Orthacanthus by
Karl von Fritsch in 1879. It came from the
Kasimovian (Carboniferous) aged
Slany Formation in the
Rakovnik Basin of
Bohemia.
P. sp., found in the
Gzhelian (Carboniferous) of
Lower Austria is undetermined. While it may represent an undescribed third species, it may just as well come from
P. jordani or
P. plicatus. ==References==
