Beaconites

Beaconites

"Beaconites" is an ichnogenus known from the Beacon sandstone, 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. Some terminate in elliptical pits, around 1.5cm in diameter, presumed to represent burrowing activity.cite journal
