New upper cretaceous (Campanian) flora from James Ross Island, Antarctica

I present a diverse previously unrecorded assemblage of leaves, cuticle, seeds and fruits from early-mid Campanian marine sediments, representing the first well-preserved macrofloristic record found in the Santa Marta Formation (north of James Ross Island, Antarctica). This new flora is diverse and...
