| Paleocoordinates: | 82.1° North, 127.8° West | ||||
| Basis of coordinate: | estimated from map | ||||
| Geographic resolution: | outcrop |
Time
| Period: | Cretaceous | Epoch: | Late/Upper Cretaceous |
| Stage: | Maastrichtian | 10 m.y. bin: | Cretaceous 8 |
| Key time interval: | Early/Lower Maastrichtian | ||
| Age range of interval: | 72.10000 - 66.00000 m.y. ago | ||
| Age estimate: | 71 Ma (Ar/Ar) to 68 Ma (K-Ar) |
Stratigraphy
| Geological group: | Colville | Formation: | Prince Creek | Member: | Kogosukruk Tongue |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 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 | |||||
Lithology and environment
| Primary lithology: | bioturbation,paleosol/pedogenic,sideritic,brown carbonaceous siltstone |
| Secondary lithology: | fine sandstone |
| Includes fossils? | Y |
| Lithology description: "Channelized facies at the Kikak-Tegoseak site are dominated by small, non-migrating (probably anastomosed) predominantly fine-grained sandstone channel fills, although larger, coarser-grained sandstone channel fills with well-developed lateral accretion surfaces (meandering channels) have been observed elsewhere within the Prince Creek Formation. Non-channelized facies represent lake, lake margin, levee and crevasse splay environments and primarily poorly drained and weakly developed paleosols. Organic-rich siltstones and coaly shales indicate abundant plant material and hydromorphic environments. Root traces, organic debris and siderite are ubiquitous elements of overbank facies. Bentonites are locally present." | |
| Environment: | delta plain |
| Geology comments: "a swampy wetland delta plain"; "Deposition occurred in trunk channels, on distributary-channel splay complexes, in interdistributary bays, and on floodplains." | |

| Collection method comments: 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." | |||
