Abstract/Summary

Terrestrial palynofloras from two localities on Williams Point, Livingston, Island, contain angiosperm monocolpates and tricolpates and can be dated as Cenomanian-early Campanian. This fixes the age for a collection of 15 silicified wood fragments described as 6 palaeotaxa; three are gymnosperm woods (Coniferwood-spacedpits, Coniferwood-clusteredpits, Coniferwood-lowrays) and three angiosperm woods (Dicotwood-heterorays, Dicotwood-multiserirays, Dicotwood-dumpirays). The palynofloras and wood specimens indicate a species rich, mixed conifer and dicotyledonous angiosperm forest possibly with a complex standard tree and understorey structure. This forest was growing at a palaeolatitude of about 59°S during the Late Cretaceous. The use of palaeotaxa rather than the ICBN system for fossil material is discussed and a brief description of the classification system proposed by Hughes (1989) is given in an Appendix.
