A study of the deposition of, and taphonomic processes affecting, plant macrofossil records for an island in Palaeolake Flixton, North Yorkshire

AbstractPlant macrofossil analysis is used in the study of developing environments and is especially applied to the study of the formation of a hydrosere, due to the excellent preservation conditions usually found in the peat associated with the lakes infilling. Modern studies of the flora present in an area and the correlation to the associated macrofossils give proxies for the study of a Palaeolake, such as Lake Flixton in the Vale of Pickering, North Yorkshire. While the proxy studies broadly concur in the approach to be taken, the deposition and taphonomy of specific plant species and the value of any results, there are elements not considered in them, one being that here are no extant studies of the dispersal of macro-remains and the associated taphonomic processes that are particular to islands within a lake. This dissertation aims to correct this by studying No Name Hill, a former island within Palaeolake Flixton. Cores for examination were collected from the island during excavations in 2018 and the resultant data compared with previous studies from other sites around the lake. While the hydroseral succession was demonstrated consistently across the lake environment, the cores from the island highlighted differential processes of deposition and taphonomy affecting the macrofossil record. It is probable that the shoreline cores give a more generic picture of the environment of the lake and surroundings, while cores taken from an island produce results which are more reflective of the localised flora.
