Short summary
The Trans-Amazon Drilling Project seeks to reconstruct the origins of biodiversity in the world's largest and most diverse rain forest, and the roles of landscape changes driven by Andean uplift and global climate change in diversification. We provide a project overview and preliminary results from a drill core from the Acre Basin of western Brazil, which recovered an 860 m sequence that was deposited in a large river system and which will yield critical insights on evolutionary history.

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.

Late Eocene to earliest Oligocene (37.97–33.06 Ma) climate and vegetation dynamics around the Tasmanian Gateway region reveal that changes in ocean circulation due to accelerated deepening of the Tasmanian Gateway may not have been solely responsible for the changes in terrestrial climate and vegetation; a series of regional and global events, including a change in stratification of water masses and changes in pCO2, may have played significant roles.

Short summary
The ANDRILL SMS site provides the first Middle Miocene Antarctic fungal record. The CREST plant-based paleoclimate reconstructions confirm an intensification of the hydrological cycle during the MCO, with the Ross Sea region reconstructed 279 % wetter than modern conditions and a maximum mean annual temperature of 10.3 °C for the warmest intervals of the MCO. The plant-based reconstructions indicate a temperate, no dry season with a warm summer (Cfb) Köppen–Geiger climate classification.
