Summary

Description
English: Evolution of the now extinct placoderms fishes during the Devonian and the early Carbonifereous as a spindle diagram. The width of the spindles are proportional to the number of families as a rough estimate of diversity. The diagram is based on Benton, M. J. (2005) Vertebrate Palaeontology, Blackwell, 3rd edition, Fig 3.25 on page 73.
