Thereare differentviews about the amount and timing of surfaceuplift in the TransantarcticMountains and the geophysicalmechanisms involved. Our new interpretationof the landscapeevolution and tectonichistory of the Dry Valleysarea of the Transantarctic Mountainsis basedon geomorphic mapping of anarea of 10,000km 2. Thelandforms are dated mainlyby their associationwith volcanicashes and glaciomarine deposits and this permitsa reconsmactionof the stagesand timing of landscapeevolution. Followinga loweringof baselevel about55 m.y. ago,there was a phaseof rapid denudationassociated with planationand escarpmentretreat, probably under semiarid conditions. -

Synoptic Taxonomy of Major Fossil Groups
APPENDIX Synoptic Taxonomy of Major Fossil Groups Important fossil taxa are listed down to the lowest practical taxonomic level; in most cases, this will be the ordinal or subordinallevel. Abbreviated stratigraphic units in parentheses (e.g., UCamb-Ree) indicate maximum range known for the group; units followed by question marks are isolated occurrences followed generally by an interval with no known representatives. Taxa with ranges to "Ree" are extant. Data are extracted principally from Harland et al. (1967), Moore et al. (1956 et seq.), Sepkoski (1982), Romer (1966), Colbert (1980), Moy-Thomas and Miles (1971), Taylor (1981), and Brasier (1980). KINGDOM MONERA Class Ciliata (cont.)
