(When I say 'first', I mean 'earliest', but the alliteration took hold of me!)
New flying fish fossils found in China provide the earliest evidence of vertebrate over-water gliding strategy.
Chinese researchers have tracked the "exceptionally well-preserved fossils" to the Middle Triassic of China (235-242 million years ago).
The Triassic period saw the re-establishment of ecosystems after the Permian mass extinction.
The fossils represent new evidence that marine ecosystems re-established more quickly than previously thought.
