1.3" Triassic Fossil Fish In Nodule - Madagascar

This is a Lower Triassic (247 million year old) fossil fish preserved inside of a concretion. These uniquely preserved fish are found by cracking open the hard concretions, and often show amazing detail such as scales and fins. There are about half a dozen different fish described from this location and the preservation makes this one hard to conclusively identify.

One half of the concretion is included.
