Live reconstruction of Eusthenopteron

  • Europe
  • Quebec (Canada)

Eusthenopteron is an extinct genus of meat -finned fishes from the Upper Devonian of North America and Europe.

Features

The animals had an elongated body, a head with small eyes and a deep foot column. He had a lung bubble next to the gills and a powerful formed fin skeleton, which enabled him well, for a short time to exit the water.

In the skeleton of the front flippers, the subsequent humerus, radius and ulna of land vertebrates already indicated. The two pointed dorsal fins were far behind the pelvic fins and the anal fin towards them. The caudal fin was tricuspid -. A very precise anatomical reconstruction gave Erik Jarvik 1980.
