Some of the oldest animals are revealed in a unique fossil site
ONE OF the core tenets of fossilisation is that hard material preserves more readily than the soft stuff. This fact has made studying the evolution of the first animals 540m years ago a bit of a problem since the vast majority lacked hard body parts. So far, only a handful of fossil sites that formed in unusual ways have allowed palaeontologists to glimpse what ancient ecosystems were like without all soft-bodied organisms being filtered out of the equation.
Qingjiang has yielded over 20,000 specimens thus far. Of these, 4,351 have been properly analysed and are thought to represent around 100 groups of creatures. Dr Zhang and his colleagues estimate that 54 of these groups have never been seen before. They include a predatory armoured arthropod , a worm with stubby legs and an animal with an ancient version of the nerve chord found in all vertebrates today. The fossils will require extensive study to determine what sorts of lives they led.
