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.

Where are the Fossils of the First Galaxies? I. Local Volume Maps and Properties of the Undetected Dwarfs [PDF]
, 2010 We present a new method for generating initial conditions for LCDM N-body simulations which provides the dynamical range necessary to follow the evolution and distribution of the fossils of the first galaxies on Local Volume, 5-10 Mpc, scales.

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.

The First Galaxies and the Likely Discovery of their Fossils in the Local Group [PDF]
, 2009 In cold dark matter cosmologies, small mass halos outnumber larger mass halos at any redshift. However, the lower bound for the mass of a galaxy is unknown, as are the typical luminosity of the smallest galaxies and their numbers in the universe.
