Also known as Chelycarapookus arcuatus type locality
Where: Victoria, Australia (37.6° S, 141.5° E: paleocoordinates 76.2° S, 97.0° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Merino Group, Early/Lower Cretaceous (145.0 - 100.5 Ma)
• an ironstone bed, three feet from the surface... in this region, the Merino Group is a seris of gently dipping arkosic sansdtones of Lower Cretaceous age
• bed-level stratigraphic resolution
Environment/lithology: fluvial; ferruginous, quartzose sandstone
•
•"Kenly (op. cit.) has shown that the ferruginous capping layer is not a stratigraphic rock unit but most likely represents an old erosional surface and is, therefore, found in rocks of different age. In some areas the laterites are fossil soils... however, in the Parish of Carapook no Tertiary sediments have been recorded, although the W. portion of the Parish has been mapped in detail, and in at least one locality the ironstone horizon is seen to transgress the bedding in the Merino Group (P. R. Kenley, pers. comm.) and is, therefore, an alteration of that Group and of Lower Cretaceous age..."
•
•"in thin-section the matrix of the specimen is similar in its constituents and grain size to rock of the ironstone horizon, which is predominantly limonite with about 20 per cent quartyz grains (Kenley, pers. comm.)
Size class: macrofossils
Preservation: cast
