Tubular microfossils from ∼2.8 to 2.7Ga-old lacustrine deposits of South Africa: A sign for early origin of eukaryotes? [PDF]
, 2016 Unequivocal evidence for Archean eukaryotic life has been long sought for and is a matter of lively debate. In the absence of unambiguous fossils this debate has focused on biogeochemical signatures and molecular phylogenies.

Declining Volatility, a General Property of Disparate Systems: From Fossils, to Stocks, to the Stars
, 2013 There may be structural principles pertaining to the general behavior of systems that lead to similarities in a variety of different contexts. Classic examples include the descriptive power of fractals, the importance of surface area to volume ...

Decoupling of morphological disparity and taxic diversity during the adaptive radiation of anomodont therapsids [PDF]
, 2013 Adaptive radiations are central to macroevolutionary theory. Whether triggered by acquisition of new traits or ecological opportunities arising from mass extinctions, it is debated whether adaptive radiations are marked by initial expansion of taxic ...

Temporal and phylogenetic evolution of the sauropod dinosaur body plan [PDF]
, 2016 The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod bauplan.

Turning setbacks into stepping-stones for growth in conservation paleobiology
Frontiers in Ecology and EvolutionConservation paleobiology is a cross-disciplinary field that utilizes the geohistorical record of past life on Earth to inform present-day decisions in conservation and restoration and assist in planning for future natural resource management.

Estimating the evolutionary rates in mosasauroids and plesiosaurs: discussion of niche occupation in Late Cretaceous seas [PDF]
PeerJ, 2020 Observations of temporal overlap of niche occupation among Late Cretaceous marine amniotes suggest that the rise and diversification of mosasauroid squamates might have been influenced by competition with or disappearance of some plesiosaur taxa.

Geological Society of America Bulletin, 2012 Systems paleobiology seeks to interpret the history of life within the framework of Earth’s environmental history, using physiology as the conceptual bridge between paleontological and geochemical data sets. In some cases, physiological performance can be estimated directly and quantitatively from fossils—this is commonly the case for vascular plant ...

Biological implications of high-energy cosmic ray induced muon flux in the extragalactic shock model
, 2011 A ~ 62 My periodicity in fossil biodiversity has been observed in independent studies of paleontology databases over ~0.5Gy. The period and phase of this biodiversity cycle coincides with the oscillation of our solar system normal to the galactic disk ...

The case for dynamic subsidence of the U.S. east coast since the Eocene [PDF]
, 2008 The dynamic subsidence of the United States east coast is addressed using the discrepancy between regional and global estimates of sea level, elevation of paleoshorelines, and adjoint models of mantle convection that assimilate plate motions and seismic ...
