NMVPL425, Koonwarra (Cretaceous of Australia)

Where: Victoria, Australia (38.6° S, 146.0° E: paleocoordinates 77.0° S, 118.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Strzelecki Group, Late/Upper Aptian (122.5 - 112.0 Ma)

• THE KOONWARRA FOSSIL BED of South Gippsland, Australia, is =8 m thick, and the invertebrate fossils occur mainly on the lower strata just above an apatite layer dated 118 ± 5 million yr old and below a layer dated 115 ± 5 million yr old (Drinnan & Chambers 1986, Jell & Duncan 1986). Orig. assigned to Korumburra Group.

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified claystone and lithified siltstone

• "Numerous aquatic and semiaquatic insects in this bed, and the finely stratified mudstone that contains them, indicate a shallow pond with marshy edges that received periodic muddy influx from a larger adjacent lake." Hamilton, 1992
• "siltstone"; "finely banded claystones and subordinate feldspathic siltstones"

Size class: mesofossils

Preservation: adpression

Collected by Talent, Duncan, Handby; P.M. Duncan in 1961; 1962-1967

Collection methods: bulk, quarrying, mechanical, sieve,

• Repository: Palaeontological Collection, Museum of Victoria, Melbourne (NMVP), Palaeontological Collection of the Department of Geology, University of Melbourne (MUGD), Australian Museum, Sydney (AMF)
