New late Paleozoic conchostracan (Crustacea: Branchiopoda) from the Shackleton Glacier Area, Antarctica: Age and paleoenvironmental implications
Lake deposits of the Pagoda Formation (Upper Carboniferous?-Lower Permian) at Mt. Butters, Shackleton Glacier area, central Transantarctic Mountains, Antarctica, yield a low diversity biota including a new species of conchostracan, Cyzicus ( Lioestheria ) shackletonensis.

Lake deposits of the Pagoda Formation (Upper Carboniferous?-Lower Permian) at Mt. Butters, Shackleton Glacier area, central Transantarctic Mountains, Antarctica, yield a low diversity biota including a new species of conchostracan, Cyzicus ( Lioestheria ) shackletonensis. Locally, conchostracans occur in large numbers near the tops of thin coarsening-upward cycles in siliciclastic sediments. Regionally, the Pagoda Formation consists of glacigenic deposits of the Gondwanide ice sheet that covered much of the land in southern high latitudes. At Mt.

Deposition from suspension within the lake was interrupted by introduction of sand and silt deposited in the conchostracan-bearing, upward-coarsening sequences.
