“…Other forms of preservation are associated with the deposition in a biotoxic environment, for example, in the famous Hallstatt saltmines, Austria (Herzig, 2009;Reschreiter and Kowarik, 2019;Haneca and Deforce, 2020;Grabner et al, 2021), and the chemical alterations of the wood tissue through carbonization and mineralization (Chabal, 1997;Tegel et al, 2016a;Haneca and Deforce, 2020). However, the most important form of wood preservation is provided by waterlogged conditions, frequently discovered at archaeological excavations, for example in water wells and other features below the groundwater level (Kretschmer et al, 2016;Croutsch et al, 2020), from pile dwellings in lakes and bogs (e.g., Bleicher, 2009;Tarrús, 2018;Benguerel et al, 2020;Hafner et al, 2021;Pranckënaitë et al, 2021), shipwrecks at the bottom of seas, lakes and rivers (e.g., Domínguez-Delmás et al, 2013;Nayling and Susperregi, 2014;Daly et al, 2021) and paleo-channels (Pilcher et al, 1977;Becker et al, 1985;Leuschner and Sass-Klaassen, 2003;Edvardsson et al, 2016b; Figure 1). Waterlogged wooden objects can be preserved for millennia (Thieme, 1997;Tegel et al, 2012;Rybníček et al, 2020).…”
