Thursius pholidotus
Traquair
This medium to large sized osteolepid is found at the start of
the Rousay Subgroup. In the fish beds it is common and in the sediments
indicating a shallow water condition only scales and plates of the head can be
found. The scales look very much like those of Gyroptychius milleri.
It is a top predator but was probably eaten by the porolepiform
Glyptolepis
