Valdivian ecosystems in the late Cretaceous and early Tertiary of Antarctica: further evidence from myrtaceous and eucryphiaceous fossil wood
Cool temperate rainforests growing on the flanks of the Andes and along the Coastal Range in Valdivia (Chile) today provide the closest analogue for the fossil floras of Antarctica during the Eocene. This paper records key Valdivian elements in a Maastrichtian to Eocene wood flora that extends the e...
