A Jurassic love song - reconstructed from the wings of a fossil katydid (http://www.youtube.com/watch?v=gC6vVmkU8i0#ws)

his video accompanied the paper 'Wing stridulation in a Jurassic katydid (Insecta, Orthoptera) produced low-pitched musical calls to attract females', published in PNAS (2011). http://www.pnas.org/content/early/2012/02/02/1118372109 (http://www.pnas.org/content/early/2012/02/02/1118372109)

Description from the paper: "At dusk, A. musicus sings in a Jurassic forest of Northwest China. The forest grew under humid conditions, probably close to the banks of a river and consisted primarily of conifers and ferns. The song was processed to take into account slight echoes produced by the lightly cluttered environment."
