The Melbourne Formation is a geologic formation in Victoria, Australia . It preserves fossils dating back to the Ludlow epoch of the Silurian period.[1][2]
Description
The Melbourne Formation, part of the Murrindindi Supergroup, is conformably overlain by the Humevale Formation and overlies the Yan Yean and Anderson Creek Formations. The formation comprises mainly thin-bedded siltstone and sandstones. Most beds show undisturbed Bouma sequences.[1]
Fossil content
The following fossils were reported from the formation:[2]
Eurypterids
Trilobites
Brachiopods
Gastropods
Bivalves
Scyphozoa
- Conulariidae indet.[4]
Corals
Ophiuroidea
Crinoids
