A new species of Antarctoxylon : a contribution to the early angiosperm ecosystem of Antarctica during the late Cretaceous
Abstract A new species of Antarctoxylon is described from the Coniacian Hidden Lake Formation of James Ross Island as A . mixai Sakala, sp. nov. This angiosperm fossil wood shows a unique combination of features in having indistinct growth ring boundaries, scalariform perforation plates with about 3...
