Around 99 million years ago, this tiny, hairy snail, called Archaeocyclotus brevivillosus, was trapped in a lump of amber, fossilising it in the process. Researchers uncovered the ninemillimetre-long snail in Hukawng Valley in northern Burma in March 2023. The Cretaceous critter would have been slowly moving through vegetation at the same time the dinosaurs walked the Earth.
