Enormous Paleozoic flesh-eaters created in lab
- Crazed boffins in the USA say they have successfully carried out a Jurassic Park-style project in which enormous flesh-eating creatures from the remote prehistoric past have been successfully bred in the laboratory. Incomprehensibly this laboratory is not located on a remote island.As many readers will doubtless be aware, during the late Paleozoic era the Earth was, if not exactly ruled or terrorised, at the least very seriously bothered by swarms of gigantic dragonflies with wingspans around 70cm across. The monster insects will have been all the more troublesome as dragonflies "need to hunt live prey", according to experts.One such expert is Dr John VandenBrooks, who has after a lengthy struggle managed to breed such much-enlarged dragonflies in his Arizona laboratory. The large size was achieved by enhancing atmospheric oxygen levels to 31 per cent, as seen in the Paleozoic (today's air is only about 20 per cent O2).
