Bioerosive traces in fossil penguin bones (Aves, Sphenisciformes) from the Eocene of Marambio/Seymour Island (West Antarctica)

We examined a set of penguin bones from different Eocene levels of the Submeseta Formation in Marambio/ Seymour Island (James Ross Basin, Antarctic Peninsula) and found the bioerosive traces fossils presented here. Traces were assigned to ?Machichnus bohemicus, Machichnus indeterminate, Nihilichnus...
