Beaconites is an ichnogenus known from the Beacon Supergroup, Antarctica, comprising a large, segmented burrow, bearing superficial resemblance to the skeleton of a snake, and probably created by a worm-like organism "shovelling" the substrate out of its way.[1] Some terminate in elliptical pits, around 1.5 cm in diameter, presumed to represent burrowing activity.[1] The producer of the trace is thought to have burrowed to a depth of no more than a few tens of centimeters.[2]
