Clusters of large Inoceramus prisms are restricted to several meters of section before abruptly disappearing. The significance of the short range of inoceramid bivalves over the shallowest sites of Shatsky Rise is currently not understood. New isotopic and benthic foraminiferal population data from these sites may provide a possible explanation to the limited stratigraphic range of inoceramids on Shatsky Rise.

Studying the LPGIA therefore has the potential to provide valuable information for understanding the Earth's transition out of the current Cenozoic ice age.

Our research in Queensland (NE Australia) suggests that rather than being a single long epoch, glaciation occurred only during discrete, relatively short-lived periods in the mid-Carboniferous (c. 315 Ma), Late Carboniferous (c. 311 Ma) and Early Permian (289-293 Ma).

Exceptional, yet to date poorly constrained examples are limestone units within the Permian System of eastern Australia. The succession consists largely of marine siliciclastics, which accumulated along the southern margin of Gondwana in a series of basins that stretched from polar to temperate latitudes.
