The Taylor Formation (Holocene) and its Macrofaunas, Taylor Dry Valley, Antarctica (Extended Abstract)

概要

Macrofaunas were collected from the New Harbor area at the entrance to the Taylor Valley during the drilling of the Dry Valley Drilling Project Holes 8 and 9. Small collections by previous workers were reviewed by SPEDEN (1962) who ascribed them to fossiliferous sediments of the Taylor Formation. Although the faunas here listed comprise the largest macrofossil collections yet made from Cenozoic deposits of the Dry Valley region of Antarctica, they are sparse with the pectinid Adamussium colbecki (SMITH, 1902) being the predominant taxon. Six molluscan species are recorded for the first time from the New Harbor deposits. It is believed that this is the first record of the gastropod taxa Subonoba contigua POWELL 1958,Lorabela plicatula (THIELE, 1912) and Philine apertissima SMITH 1902,having been found fossil. SPEDEN (1962) erected the Taylor Formation for sediments containing the New Harbor faunas. Consideration of the original description, type locality, type faunas and correlatives of the Taylor Formation leaves little doubt that this stratigraphic unit requires redefinition. It is concluded that the Taylor Formation has precedence over alternative names, and that it is a valid stratigraphic unit which should be redefined using information obtained by the Dry Valley Drilling Project.
