Manuherikia River site, Saint Bathans, Home Hills Station, HH1b (Miocene of New Zealand)

Also known as H41/f90

Where: South Island, New Zealand (44.9° S, 169.9° E: paleocoordinates 49.7° S, 179.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Casuarinaceae pollen zone, Bannockburn Formation (Manuherikia Group), Altonian (19.0 - 15.9 Ma)

• "Bed HH1a, a sand layer bound by clay layers, in the Manuherikia River section, 6.88–7.0 m above the base of the Bannockburn Formation, allocated H41/f88 in the archival Fossil Record File of the Geological Society of NZ"

•early to earliest middle Miocene (Altonian), 19-16 Ma, Casuarinacea biozone

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - large; fine-grained, gray, green, silty sandstone and claystone

• from Miocene Lake Manuherikia, which extended > 5,600 square km
• "HH1a comprises a greenish grey silt or fine sand locally intermixed with quartz granules/pebbles and organic debris, incorporating algae encrusted rip-up clasts of mud, rare oncolite fragments and abundant bone fragments. The clay layer underlying HH1a is slightly humped and hollowed (±5 cm) over its lateral extent. The fossiliferous sands deposited on this surface contain ripples, about 10–12 cm between crests that indicate a current direction essentially down dip or parallel to the adjacent Manuherikia River. A result of this is that coarser material was deposited as lenses down-current of the humps on the lower clay layer."

Size classes: macrofossils, mesofossils
