This Story Has 'Legs'

Modern millipedes are generally very unimpressive invertebrate herbivores. In spite of their name, they don't have one thousand legs. In the days of the Carboniferous period, however, the UK was much nearer the equator. At this time, giant millipedes roamed the north of England (https://www.theguardian.com/science/2021/dec/21/largest-ever-giant-millipede-fossil-found-on-uk-beach). The oldest and largest millipede fossil was recently found on a beach in Northumberland. The animal (Arthopleura) is estimated (only some segments were preserved), to have been around 2m long and weighing in at 50kg. A very rich plant diet would have been needed in that area to sustain such a beast. People have speculated that Arthopleura may have added to its calorie intake, by munching the odd amphibian or insect.
