Conifer fossil woods from the Santa Marta Formation (Upper Cretaceous), Brandy Bay, James Ross Island, Antarctica
Abstract Conifer fossil woods from the Santonian to lower Campanian Santa Marta Formation are anatomically studied in detail. The wood flora is dominated by conifers, mainly Araucariaceae. ConiferExpand

Angiosperm fossil woods from the Upper Cretaceous of Western Antarctica (Santa Marta Formation)
Abstract We identified six fossil-species of angiosperms based on fossil woods from two small collections from the Beta Member (lower Campanian) of the Santa Marta Formation on James Ross Island: 1)Expand

Mid Campanian‐Lower Maastrichtian magnetostratigraphy of the James Ross Basin, Antarctica: Chronostratigraphical implications
The James Ross Basin, in the northern Antarctic Peninsula, exposes which is probably the world thickest and most complete Late Cretaceous sedimentary succession of southern high latitudes. DespiteExpand

The Ammonite Genus Gaudryceras from the Santonian—Campanian of Antarctica: Systematics and Biostratigraphy
Abstract. Belying previous interpretations on its rarity in southern latitudes, Gaudryceras de Grossouvre is well represented in the Santonian—Campanian of Antarctica. The study of more than 300Expand

A non-aristonectine plesiosaur from Antarctica reveals new data on the mandibular symphysis of elasmosaurids
Abstract Elasmosaurids are one of the most abundant fossil marine reptile groups identified from the Upper Cretaceous strata of Antarctica. However, the documented record of intact elasmosaurid skullExpand
THE AMMONITE GENUS GAUDRYCERAS de GROSSOUVRE, 1894 FROM THE SANTONIAN-CAMPANIAN OF ANTARCTICA: SYSTEMATICS AND BIOSTRATIGRAPHY --- Preprint doi: 10.5710/AMGH.29.02.2016.2972
Gaudryceras is well represented in the Santonian-Campanian of Antarctica belying previous interpretations on its rarity in southern latitudes. The study of more than 300 specimens from the SantaExpand
Coniacian-Campanian magnetostratigraphy of the Marambio Group: The Santonian-Campanian boundary in the Antarctic Peninsula and the complete Upper Cretaceous – Lowermost Paleogene
Abstract Recent magnetostratigraphic works from different areas of the James Ross Basin have expanded on chronostratigraphic studies previously based on ammonite, palynomorph and nanoplanktonExpand
Onshore–offshore trends in Campanian ammonite facies from the Marambio Group, Antarctica: Implications for ammonite habitats
Abstract Recent biostratigraphic and sedimentologic studies in the lower–mid Campanian ammonite-rich shelf deposits of the James Ross Basin, Antarctica made possible a precise reconstruction ofExpand

The gaudryceratid ammonoids from the Upper Cretaceous of the James Ross Basin, Antarctica
We describe new material of the subfamily Gaudryceratinae in Antarctica, including five new species: Gaudryceras submurdochi Raffi and Olivero sp. nov., Anagaudryceras calabozoi Raffi and Olivero sp.Expand
