Where: South Shetland Islands, Antarctica (62.0° S, 57.6° W)

• Paleocoordinates: 21.6° S, 161.5° E (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cambrian Erratics Member (Cape Melville Formation), Atdabanian to Atdabanian (521.0 - 512.9 Ma)

• The absence of typical late Atdabanian fossils suggests a lower age limit of the fossil assemblage within the Pararaia tatei trilobite Zone (Bengtson et al. 1990) or Halkieria parva SSF “Zone” (Gravestock et al. 2001); a lower Botomian age is the most plausible because many King George Island fossils are not known from later deposits (Bengtson et al. 1990, Zhuravlev and Gravestock 1994, Wrona and Zhuravlev 1996, Gravestock et al. 2001, Wrona 2004). This assemblage is closely similar to late Atdabanian−early Botomian Australian assemblages, especially that from the Stansbury Basin, Parara Limestone of Yorke Peninsula.

• member-level stratigraphic resolution

Environment/lithology: conglomeratic limestone and lithified, burrowed, black wackestone

Size class: macrofossils

Preservation: replaced with phosphate

Collection methods: bulk, chemical

• A complementary work concerning the accompanied small skeletal fossil assemblage is presented elsewhere (Wrona 2004).
