mm = 1 inch): 106 mm long, 75 mm tall Matrix: 120 mm by 93 mm
A fine example of a nodule from the early Triassic of Madagascar
containing most of a very detailed fish known as Encrinesomus dixoni.
This one is thought to have been a still-water grazer on plants.
the incredible detail preserved here, down to the rhombic scales
and the finnage. Unlike most nodules, this one is a natural cast
of the fish, displaying the left and right sides with remarkable
fidelity. This one is missing only the distalmost portion of the
caudal fin, a fine example of a genus that went extinct during the
