“…Conversely the greatest incidence of Table 3. (B) Marine temperature curve calculated from data given in Barrera et al (1987), Ditchfield et al (1994), Pirrie and Marshall (1990) recalibrated to the recent stratigraphic interpretations and calibrations using high precision Sr ages (Crame et al, 2004). Ditchfield et al (1994) calculated average temperatures for individual formations in this study we selected samples that now have good stratigraphic control and recalculated average temperatures from this data.…”

Fossil wood is abundant throughout the Cretaceous and Tertiary sequences of the northern Antarctic Peninsula region. The fossil wood represents the remains of the vegetation that once grew at the southern high palaeolatitudes at 59-628S through the general decline in climate, from the Late Cretaceous global warmth through to the mid-Eocene cool period prior to the onset of glaciation. This study draws on the largest dataset ever compiled of Antarctic conifer and angiosperm woods in order to derive clearer insights into the palaeoclimate. Parameters including mean annual temperature, mean annual range in temperature, cold month mean, warm month mean, mean annual precipitation are recorded. The fossil wood assemblages have been analysed using anatomical (physiognomic) characteristics to determine the palaeoclimate variables from the Coniacian-Campanian to the middle Eocene. These results are compared with data derived from Coexistence Analysis of the fossil floras (composed of leaves, wood and palynomorphs) and published data based on leaf physiognomic characters. These studies indicate a relatively warm and wet Late Cretaceous that becomes drier and cooler in the Early Paleocene and subsequently returns to warmer, wetter conditions by the latest Early Paleocene. During the Eocene the climate becomes relatively cool and dry once again. The discrepancies obtained from these two methods coupled with other published data are discussed in the context of the fluctuations in the temperatures of the surrounding oceans and global patterns of climate change.

“…The Marambio Group, which crops out mostly in the James Ross Archipelago, was deposited during the upper ConiacianÁDanian interval (Macellari 1988;Ineson 1989;McArthur et al 2000;Crame et al 2004) or SantonianÁ Danian (Olivero & Medina 2000). This article follows the stratigraphy proposed by Olivero et al (2008) Crame et al (1991) (Figs.…”

Elasmosaurs are recorded for the first time in the Lachman Crags Member (Beta Member) of the Santa Marta Formation (lower Campanian) and in the Herbert Sound Member of the Snow Hill Island Formation (upper Campanian). These are the first elasmosaurids from James Ross Island, Antarctic Peninsula. These records greatly improve our knowledge of the taxonomic diversity of plesiosaurs of the Santa Marta Formation and Herbert Sound Member of the Snow Hill Island Formation, and extend the lower limit of the record of Elasmosauridae in Antarctica to the lower Campanian, making this the oldest record of an Antarctic elasmosaur
