Highlights
Well-preserved fossil starfish material is recorded from the Eocene La Meseta Formation exposed in Seymour Island, Antarctica
The use of new technology on several fragments enabled the visualization of new characters and the differentiation of a new species, Zoroaster marambioensis sp. nov., which was previously identified as Zoroaster aff
The depositional setting represents the outer zone of an estuary dominated by marine processes affected by long lived hyperpycnal flows
Summary
Well-preserved fossil starfish material is recorded from the Eocene La Meseta Formation exposed in Seymour Island, Antarctica. The use of new technology (i.e., microCT) on several fragments enabled the visualization of new characters and the differentiation of a new species, Zoroaster marambioensis sp. Nov., which was previously identified as Zoroaster aff.
