Amphistium Fossil Fish Pendant

Amphistium is a fossil fish that lived 50 million years ago. It demonstrates the evolution from symmetrical eye placement on fish to the asymmetrical eye placement of flatfish like halibut. Flatfish who scud along the ocean floor don't need eyes facing the ocean bed, and therefore have evolved to have two eyes facing upward on one side of their body. Amphistium is an intermediate stage in which one eye has begun to migrate up the head  to cross over to the other side of the body. Amphistium is considered a transitional fossil in evolution (M. Friedman, Nature 2008 Jul 10;454(7201):209-12).

The pendant is 2.52 cm (1 inch) long and 1.6 cm (0.62 inches) wide.

The pendant is 3D printed in 14K gold plated brass or sterling silver, finished with a 45 cm/18 inch long gold plated silver chain or silver chain to match, and is ready for gift giving with a gift box, polishing cloth, and care instructions.
