Lowana Road - Macquarie Harbour (Eocene of Australia)

Where: Tasmania, Australia (42.2° S, 145.4° E: paleocoordinates 64.1° S, 152.6° E)

• coordinate stated in text

When: Upper Malvacipollis diversus pollen zone, Macquarie Harbor Formation, Early/Lower Eocene (55.8 - 48.6 Ma)

• Both spore-pollen and marine dinoflagellate assemblages from these beds are correlative with the mid- Ypresian or Planktonic Foraminiferal Zone P7 (Carpenter et al., 2007 ) (early Eocene; 52 – 51 Ma).

Environment/lithology: estuary or bay; carbonaceous mudstone

• The sediments were deposited in a quietwater estuarine setting with tidal influence (Carpenter, 2007).
• carbonaceous estuarine mudstones in the upper part of the Macquarie Harbor Formation (Mcloughlin et al., 2008).

Size class: macrofossils

Preservation: mold/impression, adpression

Collection methods: chemical, hydroflouric

• The specimen was recovered from a new site on Lowana Road, Regatta Point, as part of a collection of fossil material made by G. J. Jordan in 2003.
