Archaboilus musicus

Archaboilus musicus is an extinct bush-cricket that lived during the Jurassic period 165 million years ago.

Although behaviors are difficult to reconstruct for extinct species, in 2012 British scientists recreated the cricket's call based on a well-preserved fossil from China.

Based on studies, it is believed that male A. musicus produced pure-tone (musical) songs using a resonant mechanism tuned at a frequency of 6.4 kHz.
