Early groups like Acanthostega had eight digits, while the more derived Ichthyostega had seven digits, the yet-more derived Tulerpeton had six toes.Crassigyrinus from the fossil-poor Romer's gap in early Carboniferous is usually thought to have had five digits to each foot. The amphibian Anthracosaurs had a five-toe pattern still found in their Amniote descendants, while further reduction had taken place on other Labyrinthodont lines, leaving the forefoot with four toes and the hind foot with five, a pattern still found in modern amphibians. ^[1]
