Scientific Notes:

Dipterus valenciennesi is a key transitional genus in vertebrate evolution. As an early lungfish, Dipterus bridges the anatomical gap between primitive bony fish and tetrapods. It possessed both gills and rudimentary lungs, enabling survival in low-oxygen freshwater environments. Achanarras Quarry is a world-famous site known for producing exceptionally preserved Devonian fish fossils.
