Mesozoic vertebrates of Europe

Belonochasma (meaning "needle mouth") is a genus of reptile from the Mesozoic (possibly Jurassic) of Franconia, Bavaria, Germany. The type species, B. aenigmaticum, was described in 1939. It was once thought to be a pterosaur, but this was rejected by Oskar Kuhn in 1961, and upheld by Peter Wellnhofer in 1978.
