A marine arthropod with long, three-pronged claws has been described from 505-million-year-old fossils.


David Legg at Imperial College London named the creature Kootenichela deppi after Kootenay National Park in British Columbia, Canada, where the fossils were found; chela, the Latin for claw; and Johnny Depp, the actor who played the blade-fingered Edward Scissorhands in the film of the same name. Fossils have been given similarly whimsical names before; for example, one arthropod was called Han solo.

K. deppi (pictured) was described on the basis of three specimens. Legg puts the sharp-handed beast in the arthropod class Megacheira (great appendage). He also reassigns Worthenella cambria, which was originally described in 1911 as a segmented worm, as a sister megacheiran.
