Australian Pterygotid III (Devonian of Australia)

Where: Victoria, Australia (37.0° S, 143.4° E: paleocoordinates 21.1° S, 170.7° E)

When: Montys Hut Formation (Walhalla Group), Emsian (407.6 - 393.3 Ma)

Environment/lithology: marginal marine; lithified siltstone and lithified claystone

• This unit likely formed in quiet bottom water conditions (Edwards et al.,

•1997). This is supported by the associated brachiopod assemblage (the

•Taungurungetes taggertyensis assemblage, see Earp, 2016) which resembles

•the BA2 chonetids community of Boucot (1975, p. 17, fig. 8). This community is typically found in intertidal, quiet (very low energy) water environments, with a maximum water depth of approximately 10 m.

• All specimens are preserved as almost completely flat, cream or grey coloured impressions on cream coloured silt- to claystone.

Size class: macrofossils
