Current interest and debate on pollen-assemblage richness as a proxy for past plant
richness have prompted us to review recent developments in assessing whether modern …

Non‐avian dinosaurs went extinct 66 million years ago, geologically coincident with the
impact of a large bolide (comet or asteroid) during an interval of massive volcanic eruptions …

The question why non-avian dinosaurs went extinct 66 million years ago (Ma) remains
unresolved because of the coarseness of the fossil record. A sudden extinction caused by …

Abstract Changes in pollen and spore assemblages across the Cretaceous–Paleogene (K–
Pg) boundary elucidate the vegetation response to a global environmental crisis triggered …

Aim I re‐evaluate the specific biogeographical significance of each of the land bridges
(Beringia, Thulean and De Geer) in the Northern Hemisphere during the latest Cretaceous …

Background During much of the Late Cretaceous, a shallow, epeiric sea divided North
America into eastern and western landmasses. The western landmass, known as Laramidia …

In the lead-up to the Cretaceous/Paleogene mass extinction, dinosaur diversity is argued to
have been either in long-term decline, or thriving until their sudden demise. The latest …

It is often postulated that mammalian diversity was suppressed during the Mesozoic Era and
increased rapidly after the Cretaceous–Palaeogene (K–Pg) extinction event. We test this …

To infer genuine patterns of biodiversity change in the fossil record, we must be able to
accurately estimate relative differences in numbers of taxa (richness) despite considerable …

Dinosaurs dominated Mesozoic terrestrial ecosystems globally. However, whereas a pole-to-
pole geographic distribution characterized ornithischians and theropods, sauropods were …
