The role of fossils in dating the tree of life has been misunderstood. Fossils can provide
good “minimum” age estimates for branches in the tree, but “maximum” constraints on those …

Cretaceous sedimentary rocks of the James Ross Basin offer a unique Austral record of the
transition from mild mid-Turonian–early Campanian to relatively cold Maastrichtian …

Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are
fundamental to nearly every evolutionary model and process. Rates need dates. There is …

The editor and coordinator of this new 284 pages study on the New Zealand Geological
Timescale, Roger A. Cooper, and his team of 22 New Zealand and foreign experts are to be …

Fossil wood is abundant in Cretaceous and early Tertiary sediments of the northern Antarctic
Peninsula region. The wood represents the remains of vegetation that once grew in high …

Basaltic volcanism in the James Ross Island region has been persistent over the last 6
million years resulting in at least 50 mainly effusive eruptions that are preserved …

Application of a strontium isotope stratigraphy to the Late Cretaceous sedimentary
succession of Antarctica has provided the impetus for a comprehensive stratigraphical …

Debate continues about the nature of the Cretaceous–Paleogene (K–Pg) mass extinction
event. An abrupt crisis triggered by a bolide impact contrasts with ideas of a more gradual …

A high-resolution sedimentological and palynological study was performed in combination
with biomarker-based organic geochemical temperature proxies TEX 86 and MBT′/CBT …

Fossil vertebrates from Antarctica are considerably rare, hampering our understanding of the
evolutionary history of the biota from that continent. For several austral summers, the …
