Phylogenetics and the Cenozoic radiation of lampreys
Current Biology, 2023The development of a movable jaw is one of the most important transitions in the evolutionary history of animals.1 Jawed vertebrates rapidly diversified after appearing approximately 470 million years ago. Today, only lampreys and hagfishes represent the once dominant jawless grade2,3,4 and comprise less than 1% of living vertebrate species.

Abstract For the Cenozoic era there are a number of well-documented extinction events both in the marine and terrestrial realms, a few of which qualify as mass extinctions. Our knowledge of Cenozoic environments, considerably enhanced within the last few decades by an extensive programme of deep-sea drilling, is greater than that for ...

Short Courses in Paleontology, 1995
Radiolarians are marine zooplankton possessing a tough, central capsular membrane that divides the cytoplasm into intracapsular (containing the nucleus, organelles, and food reserves) and extracapsular (with food-gathering rhizopodia and digestive vacuoles) portions (Figure 1). They bear two kinds of pseudopodia, the axopodia and filopodia.

Cenozoic Plant Diversity in the Neotropics
Science, 2006Several mechanisms have been proposed to explain the high levels of plant diversity in the Neotropics today, but little is known about diversification patterns of Neotropical floras through geological time. Here, we present the longest time series compiled for palynological plant diversity of the Neotropics (15 stratigraphic sections, 1530 samples ...

Cenozoic Volcanic Activity in Greece
Acta Vulcanologica : journal of the national volcanic group of Italy, 2009The present paper is a brief review of Cenozoic volcanism in Greece, as revealed by the last 40 years of research activity, mostly undertaken through collaboration between Italian and Greek researchers. Fabrizio Innocenti was one of the main contributors to these studies, which led to a substantial understanding of Greek magmatism and its relationship ...

The Cenozoic mineralization in structures associated with the Red River shear zone (RRSZ) in northern Viet Nam includes the following mineralized ore types TR- (U-Th)-Pb-Zn and TR- (U-Th) –Ba-F, Au-Cu in the Song Da rift zone. The origin of the mineralizations is spatially and (possibly) temporally related to the formation of Paleogene potassic mafic –

Thresholds for Cenozoic bipolar glaciation
Nature, 2008The long-standing view of Earth's Cenozoic glacial history calls for the first continental-scale glaciation of Antarctica in the earliest Oligocene epoch ( approximately 33.6 million years ago), followed by the onset of northern-hemispheric glacial cycles in the late Pliocene epoch, about 31 million years later.

Paleobiology, 1981
Birds have traditionally been termed the best known group of vertebrates. This cliché, however, relates to the fact that living species are well described, even to the subspecies level. Birds are well known because they are diurnal (therefore easily observed) and because of their aesthetic appeal—birds are beautiful.
