TWO OSTEOLEPIS - DEVONIAN, ORKNEY.


Osteolepis macrolepidotus Agassiz, 1835.

Square slab of grey flagstone. On one surface are two complete fish with the head of one lying underneath the other fish. The larger fish is covered with black shiny scales. Beautifully preserved with all the fins showing. The other fish has a different sort of preservation. The scales are not shiny black, only in patches. The body is mostly covered in sculptured scales with a definite surface pattern. This appears to be some sort of seasonal variation possibly to do with spawning or even a gender basis. Osteolepids were 'lobe - finned' fishes which were the direct ancestors of Amphibians. Nice interesting piece.

Middle Devonian, uppermost Eifelian, Sandwick Fish Bed.
 Tronston, Orkney, Scotland.

Matrix : 17 x 16 x 2.5 cm.
Largest fish : 15.2cm. long.
