Collection methods and comments
| Collection methods: | selective quarrying,sieve |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: In 1990, 174 kg of peat and silt from six samples was collected from the three organic horizons at depths of 0–60, 120–155, and 245–255 cm, respectively (Fig. 2). The 0-cm data position was defined at the top of the upper organic horizon. Chitinous remains of insects were recovered from the samples using a kerosene flotation technique (Ashworth, 1979). Disaggregation of highly compressed peats was aided by soaking them in a 5% NaOH solution. Arthropod remains were abundant and well preserved in all samples. All specimens, including those examined by Totten and Coope in 1967, were mounted onto micropaleontological slides and reposited in the Quaternary Entomology Laboratory at North Dakota State University. | |
