Devonian Fish Scotland

This Tristichopterus is an excellent match for Concestor 18 in Richard Dawkins' book "The Ancestor's Tale."

The Gyroptychius is another spectacular lobe-finned fish also from the Scottish Middle Devonian.

I have also added the lungfishes Pentlandia and a juvenile Eusthenopteron from Miguasha, Quebec.
