Short summary
A diverse suite of “fossils” associated with the ~1.5 Ga Volyn (Ukraine) kerite was published recently. We show that at least some of them represent modern contamination including plant hairs, pollen, and likely later fungal growth. Comparable diversity is shown to exist in moderm museum dust, calling into question whether any part of the Volyn biota is of biological origin while emphasising the need for scrupulous care in collecting, analysing, and identifying Precambrian microfossils.

Rate-of-change records based on compositional data are ambiguous as they may rise irrespective of the underlying trajectory of ecosystems. We emphasize the importance of characterizing both the direction and the rate of palaeoecological changes in terms of key features of ecosystems rather than solely on community composition. Past accelerations of community transformation may document the potential of ecosystems to rapidly recover important ecological attributes and functions.

The Volyn biota (Ukraine), previously assumed to be an extreme case of natural, abiotic synthesis of organic matter, is more likely a diverse assemblage of fossils from the deep biosphere. Although contamination by modern organisms cannot completely be ruled out, it is unlikely, considering all aspects, i. e. their mode of occurrence in the deep biosphere, their fossilization and mature state of organic matter, their isotope signature, and their large morphological diversity.

Significant climatic changes affected Europe's landscape, animals, and human groups during the Late Pleistocene. Reconstructing the local conditions humans faced is essential to understand adaptation processes and resilience. This study analyzed the chemical composition of animal teeth consumed by humans in northern Iberia, spanning 80,000 to 15,000 years, revealing the ecological changing conditios.

This study looked into the regional and global response of planktonic foraminifera to the climate over the last 5 million years, when the Earth cooled significantly. These single celled organisms exhibit the best fossil record available to science. We document an abundance switch from warm water to cold water species as the Earth cooled. Moreover, a closer analysis of certain species may indicate higher fossil diversity than previously thought, which has implications for evolutionary studies.

Deep-living organisms are a major yet poorly known component of ocean biomass. Here we reconstruct the evolution of deep-living zooplankton and phytoplankton. Deep-dwelling zooplankton and phytoplankton did not occur 15 Myr ago, when the ocean was several degrees warmer than today. Deep-dwelling species first evolve around 7.5 Myr ago, following global climate cooling. Their evolution was driven by colder ocean temperatures allowing more food, oxygen, and light at depth.

Short summary
Benthic foraminifera play a significant role in modern reefal ecosystems mainly due to their symbiosis with photosynthetic microorganisms. Foraminifera were also components of Devonian stromatoporoid coral reefs; however, whether they could have harbored symbionts has remained unclear. We show that Devonian foraminifera may have stayed photosynthetically active, which likely had an impact on their evolutionary radiation and possibly also on the functioning of Paleozoic shallow marine ecosystems.

This paper is a step towards understanding the basal peat ecosystem beneath the North Sea. Plant remains followed parallel sequences. Methane concentrations were low with local exceptions, with the source likely being trapped pockets of millennia-old methane. Microbial community structure indicated the absence of a biofilter and was diverse across sites. Large carbon stores in the presence of methanogens and in the absence of methanotrophs have the potential to be metabolized into methane.

The exploitation of deep-sea sedimentary archive relies on the recovery of mineralized skeletons of pelagic organisms. Planktonic groups leaving preserved remains represent only a fraction of the total marine diversity. Environmental DNA left by non-fossil organisms is a promising source of information for paleo-reconstructions. Here we show how planktonic-derived environmental DNA preserves ecological structure of planktonic communities. We use planktonic foraminifera as a case study.

A comparative analysis of the metagenomes from two 30,000-year-old permafrost samples, one of lake-alluvial origin and the other from late Pleistocene Ice Complex sediments, revealed significant differences within microbial communities. The late Pleistocene Ice Complex sediments (which are characterized by the absence of methane with lower values of redox potential and Fe2+ content) showed both a low abundance of methanogenic archaea and enzymes from the carbon, nitrogen, and sulfur cycles.

We measured the oxygen isotopic composition of Late Jurassic chondrichthyan teeth (sharks, rays, chimaeras) from the Swiss Jura to get ecological information. The main finding is that the extinct shark Asteracanthus (Hybodontiformes) could inhabit reduced salinity areas, although previous studies on other European localities always resulted in a clear marine isotopic signal for this genus. We propose a mainly marine ecology coupled with excursions into areas of lower salinity in our study site.

Short summary
The Smithian--Spathian boundary was a key event in the recovery of marine environments and ecosystems following the end-Permian mass extinction ~1.5 million years earlier. Our analysis of the Shitouzhai section in South China reveals major changes in oceanographic conditions at the SSB intensification of oceanic circulation leading to enhanced upwelling of nutrient- and sulfide-rich deep waters and coinciding with an abrupt cooling that terminated the Early Triassic hothouse climate.
