Also known as Kikak Creek, Kekak-Tegoseak, KKT

Where: North Slope County, Alaska (69.8° N, 151.5° W: paleocoordinates 82.1° N, 127.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Kogosukruk Tongue Member (Prince Creek Formation), Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• Radioisotopic dates derived from multiple tuff beds throughout this section of the Prince Creek Formation range from 68Ma to 71Ma, with an average estimate of 69.1+/20.3Ma, placing it in the early Late Maastrichtian. Palynological samples from the Kikak-Tegoseak Quarry itself correlate reasonably well with the radioisotopic data, showing an Early Maastrichtian assemblage

• bed-level stratigraphic resolution

Environment/lithology: delta plain; bioturbated, paleosol/pedogenic, sideritic, brown, carbonaceous siltstone and fine-grained sandstone

Size classes: macrofossils, mesofossils, microfossils

• ceratopsian herd caught in seasonal runoff flood, then mixed and buried with other taxa; dermestid scavenging prior to burial; little subaerial exposure/weathering stages 0-2;

Collected by University of Alaska Museum in 1994-2007

Collection methods: quarrying, surface (float), surface (in situ), mechanical,

• For Nanuqsaurus: "The blocks were individually removed; some were wrapped in aluminum foil, then placed in sealed plastic buckets for transport out of the field area, and shipped to Dallas, Texas. Preparation was conducted in the Paleontology Lab of the Perot Museum of Nature and Science (DMNH; Dallas, Texas, USA). The specimens were extracted from the blocks using manual pneumatic tools (‘airscribes’) to remove the hard, fine-grained rock from the bones, with finer cleaning and detail work performed with sharpened tungsten-carbide points mounted in pin-vices. Broken parts were glued together using Butvar B-76 dissolved in acetone to a thick consistency. More fragile areas were treated with very dilute Butvar B-76 dissolved in acetone to allow deeper penetration of the solution into small cracks and porous areas. Molds of the specimens were made using room-temperature vulcanizing platinum-cure silicone rubber. The specimens are now housed in the collection of the Perot Museum of Nature and Science."
