Here, I use closely related gastropod species alive in the seas today to offer insights into the lifestyles and habitats of extinct Eocene species.

Working methods for the study of such deposits need to be multi-proxy and process-sedimentological and not start with presumptions based on former models or interpretations. For instance, the detailed documentation of pavements, dropstones and erratics indicate that a shift from glaciogenic interpretations to SGFs for many pre-Pleistocene diamictites is needed. In another example, surface microtextures (SM) formed by glaciers display a combination of large-scale fractures and (irregular) abrasion, in contrast to non-glacial environments, and may therefore be used as a quick diagnostic working tool.</p>","PeriodicalId":100581,"journal":{"name":"Geology Today","volume":"41 1","pages":"10-18"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These features have made this place an important area for geoscience research, as well as an important area for the development of geotourism. Cherrapunji is also the source of the ‘Meghalayan Age’, the most recent age in the geological timescale, defined by the International Commission on Stratigraphy (ICS) in 2018, for the past 4200 years of the Holocene.

Preparing for an uncertain future climate represents one of the biggest challenges humans have ever faced. Here, I take you back 62 million years ago (Ma) to a poorly studied short-lived global warming event known as the Latest Danian Event (LDE), which may represent a good analogue for current human-induced climate change. I discuss evidence for changes in temperature and pH of the oceans during the LDE, using novel geochemical proxies on the calcite shells of zooplankton to prove that the LDE was the first global ‘hyperthermal’ event of the Cenozoic. I also delve into the potential forcing mechanisms behind the event, outlining the critical outstanding questions which palaeoclimatologists are yet to answer.
