Soft‐Bodied Fossils Are Not Simply Rotten Carcasses – Toward a Holistic Understanding of Exceptional Fossil Preservation

open access: yesBioessays, 2018
Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation ...

How Technology Has Thrown Us Out of Balance with Nature and Why We Need to Get Back In

open access: yesMolecular Frontiers Journal, 2020
We have created a technology-based environment in an effort to control our world, but we need to understand that the biological forces that shaped us continue to play a role in our future. As more and more species go extinct because of human activity, we

A Field Guide to Finding Fossils on Mars

open access: yesJournal of Geophysical Research - Planets, 2018
The Martian surface is cold, dry, exposed to biologically harmful radiation and apparently barren today. Nevertheless, there is clear geological evidence for warmer, wetter intervals in the past that could have supported life at or near the surface. This

A Revised Phylogenetic Classification for Viola (Violaceae)

open access: yesPlants, 2022
The genus Viola (Violaceae) is among the 40–50 largest genera among angiosperms, yet its taxonomy has not been revised for nearly a century. In the most recent revision, by Wilhelm Becker in 1925, the then-known 400 species were distributed among 14 ...

Preservation of Arctic dinosaur remains from the Prince Creek Formation (Alaska, USA): A reply to Fiorillo (2016) [PDF]

open access: yesActa Palaeontologica Polonica, 2016
We thank Anthony Fiorillo (2016) for the concerns he raised regarding our characterizations of the Liscomb bonebed fossils in our paper describing Ugrunaaluk kuukpikenis from the Prince Creek Formation of Alaska, USA (Mori et al. 2016). We did not

Congruence, fossils and the evolutionary tree of rodents and lagomorphs

open access: yesRoyal Society Open Science, 2019
Given an evolutionary process, we expect distinct categories of heritable data, sampled in ever larger amounts, to converge on a single tree of historical relationships.

Rethinking Living Fossils

open access: yesBioScience, 2018
Biologists would be mistaken if they relegated living fossils to paleontological inquiry or assumed that the concept is dead. It is now used to describe entities ranging from viruses to higher taxa, despite recent warnings of misleading inferences ...

From fossils to mind

open access: yesCommunications Biology, 2023
AbstractFossil endocasts record features of brains from the past: size, shape, vasculature, and gyrification. These data, alongside experimental and comparative evidence, are needed to resolve questions about brain energetics, cognitive specializations, and developmental plasticity.

The Messel Pit: Window into a Greenhouse World [PDF]

open access: yesGeoconservation Research, 2021
Anthropogenic climate change may result, within 200 years, in warm and equable climatic conditions not experienced on Earth for tens of millions of years. Ancient ecosystems under such “greenhouse” conditions may be seen as natural experiments, and their
