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

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

Seeds, 2023 Physical dormancy (PY) due to a water-impermeable seed/fruit coat is one of the characteristic features of many species of Fabaceae; however, the timing and context of the evolution of this trait are poorly understood.

Insect frass in Baltic amber [PDF]
Bulletin of the Geological Society of Finland, 2008 Inclusions of wood debris loosened from pine-like trees are abundant in Baltic amber of Eocene and Oligocene age. The possibilities to find insect frass and excrement among wood debris are outlined and some examples are given.

Fossilized bioelectric wire – the trace fossil Trichichnus [PDF]
Biogeosciences, 2014 Abstract. The trace fossil Trichichnus is proposed as an indicator of fossil bioelectric bacterial activity at the oxic–anoxic interface zone of marine sediments. This fulfils the idea that such processes, commonly found in the modern realm, should be also present in the geological past.

The first animals : ca. 760-million-year-old sponge-like fossils from Namibia [PDF]
, 2012 One of the most profound events in biospheric evolution was the emergence of animals, which is thought to have occurred some 600–650 Ma. Here we report on the discovery of phosphatised body fossils that we interpret as ancient sponge-like fossils and ...

Virtual fossils: a new resource for science communication in paleontology [PDF]
, 2012 Computer-aided 3-D reconstruction of fossils, or virtual paleontology, is an increasingly common and powerful technique. It is now regularly used for research in paleontology, yet to date has impacted little on public outreach and science communication ...

Geology Today, 2008 Possibly every palaeontologist, before and after Charles Darwin, has been well aware that the fossil record is very incomplete. Only a tiny percentage of the plants and animals alive at any one time in the past get preserved as fossils, both in terms of numbers of individuals and in terms of numbers of species.
