MESACANTHUS - EARLY DEVONIAN, SCOTLAND.


Mesacanthus mitchelli Egerton.

Split 'tile of grey shale. Positive and negative halves. Towards one end is the remains of a small Acanthodian fish. Acanthodians were covered in tiny scales and had spines supporting the fins. Under magnification there is a 3D jumbled mass of scales and quite a number of spines. All the spines are lying in the same direction. This would indicate that the fish has been either regurgitated by a predator or that this is a coprolitic mass. These tiny fish were preyed upon by a much larger Acanthodian, Parexus sp. This has to be a Parexus meal. Lower down the matrix is another splatter or organic material.

Lower Devonian, Lockovian, Arbuthnott Group.
Tillywhandland quarry, Turin Hill near Forfar, Scotland

Matrix : 7.5 x 4.5 cm.
