http://blog.wired.com/defense/2007/11/anderson-based.html The Vertipod looks a bit like a one-passenger helicopter turned upside-down. Its propeller is on the bottom and the pilot stands on a platform built around it with back support and controls at waist-level.
It is powered by a 440-cubic-centimeter engine that runs on gasoline or ethanol and can be activated with a pull-start, like a lawnmower. The VertiPod is intended to travel five to 15 feet above ground at a top speed of 40 mph. Bitar said it will be sold for $10,000 in a kit that can be assembled in a weekend.

http://uk.reuters.com/article/domesticNews/idUKL2161277720071121LONDON (Reuters) - Scientists have found the fossilised claw of a 2.5-metre (8-foot) sea scorpion, a nightmarish creature living before the age of dinosaurs.
The claw of the sea scorpion Jaekelopterus rhenaniae measured 46 centimetres (18 inches) long, indicating the creature was half a metre longer than previous estimates of the ancient arthropods.
Just why prehistoric arthropods -- creatures with external skeletons and segmented bodies -- grew so large is unclear. Some scientists believe they may have become giants because of the higher levels of oxygen in the atmosphere in the past.
