Cement Mills, Gore
Basic information
Sample name: Cement Mills, Gore
Reference: A. Bartholomai. 1977. The fossil vertebrate fauna from Pleistocene deposits at Cement Mills, Gore, southeastern Queensland. Memoirs of the Queensland Museum 18(1):41-51 [ER 3691]
Geography
Country: Australia
State: Queensland
Coordinate: 28° 16' 48" S, 151° 28' 48" E
Coordinate basis: stated in text
Time interval: Late Pleistocene
Min Ma: 0.0536
Age basis: U/Th
Geography comments: "Cement Mills, Gore, is located approximately 70 km northeast of Texas", a town in the Goondiwindi Region of southern Queensland.
U/Th dating of two megafaunal teeth from the deposit "yielded almost identical ages of 53.6 ± 0.2 ka and 53.9 ± 0.3 ka" (Price et al. 2009).
These dates most likely represent minimum ages for the fossil accumulation, due to the nature of U/Th dating on fossil bone and teeth.

Environment
Lithology: siliciclastic (mixed)
Taphonomic context: carnivore accumulation,cave,fissure fill
Habitat comments: "The cave and fissure deposits from Cement Mills occur in the Devonian–Carboniferous limestones of the Texas Beds that form part of the larger Wooloomin-Texas Block of the New England Fold Belt".
"Fossiliferous sediments are represented by cemented breccia fissure-fills and cemented cave floor sediments that are dominated by clays, silts and carbonate nodules".
"Only a single stratigraphic faunal-bearing unit has been recognised within the deposit".
"Faunal elements likely entered the caves and fissures via marsupial predators that used the caves as lairs, and wash and fill processes".
