Pterichthyodes milleri (Miller ex Agassiz MS)
This fish is known from the lowest part of the Sandwick Fish Bed where it is often found as juvenile specimens together with remains of Dipterus valenciennesi . Probably the fish did not live in the lake but was transported by rivers. In the Moray Firth Area of Scotland many localities are known where Pterichthyodes is found articulated. All these localities indicate more a river than a lake environment.
The weathered specimen shown, is unusual large for the Sandwick Fish Bed. See also the juvenile specimen. The tiny specimen is from the Moray Firth area. In sediments directly above the Sandwick Fish Bed disarticulated specimens were found.
