When did Eusthenopteron go extinct?
about 370 million years ago
Eusthenopteron, genus of extinct lobe-finned fishes (crossopterygians) preserved as fossils in rocks of the late Devonian Period (about 370 million years ago). Eusthenopteron was near the main line of evolution leading to the first terrestrial vertebrates, the tetrapods.

This very ancient, but highly advanced fish species possessed lungs as well as gills, and was able to use its fins as rudimentary feet. These exciting fossils were found in the Gaspésie region of Quebec, in 375 million-year-old sedimentary rocks. The species was named Eusthenopteron foordi.

What made the Tiktaalik go extinct?
What remains mysterious is exactly what happened 360 million years ago to trigger this mass extinction, the authors said. Other researchers have found evidence of substantial glacier formation at the end of the Devonian period, which would dramatically lower sea levels and affect the life within.
