WASHINGTON,: The call of a Jurassic-era cricket was simple, pure and capable of traveling long distances in the night, said scientists who reconstructed the creature’s love song from a 165 million year old fossil.

British scientists based their work out Monday on an extremely well preserved fossil of a katydid, or bush cricket, from China named Archaboilus musicus. The cricket lived in an era when dinosaurs roamed the earth.

The detailed wings, measuring about 72 millimeters  long, allowed scientists to recreate for the first time the features that would have produced sound when rubbed together.

The result is “possibly the most ancient known musical song documented to date,” said the study which appears in the US journal the Proceedings of the National Academy of Sciences.

The ancient katydid’s call should be imagined against a busy backdrop of waterfalls, wind, the sound of water coursing through streams and other amphibians and insects serenading would-be mates, the study authors said.

“This Jurassic bush cricket... helps us learn a little more about the ambiance of a world long gone,” said co-author Fernando Montealegre-Zapata of the University of Bristol.

A simple call may have been the creature’s best shot at attracting a mate in the nighttime forest, said co-author Daniel Robert, an expert in the biomechanics of singing and hearing in insects at the University of Bristol.

“Singing loud and clear advertises the presence, location and quality of the singer, a message that females choose to respond to -- or not,” he said.

“Using a single tone, the male’s call carries further and better, and therefore is likely to serenade more females.”However, the long-extinct katydid may have been alerting predators to his location, too. Some 100 million years later, insects began developing the ability to make sounds at frequencies their enemies, like bats, could not hear.

Your measurements appear to be inaccurate. 72 centimeters is about 28 inches, but 3/4 of a inch is about 2 centimeters. I suspect the correct measurement is the latter.

72 centimetres = 3/4 of an inch? That's some odd math, as there are 2.54 centimetres in one full inch. Further, 72 millimetres is 7.2 centimetres, which in turn is 2.834 inches. That means you probably didn't mean millimetres. How big are these creatures wings, seeing how nothing you wrote can remotely be accurate?

Get accurate measurements. This is supposed to be a scientific column. Come on!... 75 centimeter is not 3/4 of an inch. Go back to school. Blatant ignorance...

I doubt 72cm = 3 quarters of an inch.
