| Sample 3-1, LC-II pit, Lost Chicken site | Matthews J. V., Westgate J. A., et al (2003) | Sample from peat just below unit F. Lost Chicken tephra dated at 2.6 +/- 0.45 Ma based on zircon fission-track. Unit C sediments just below LCT at Section 91-2 have a normal remanent magnetic polarity (Fig. 3), which suggests that LCT was deposited during the youngest normal subchron of the Gauss chron, that is, between 2.581 and 3.040 myr (Cande and Kent, 1995). The reversed magnetic polarity of Unit A likely means that it was deposited during the Kaena subchron (3.040–3.110 myr; Cande and Kent | peat | 2.588 - 1.806 Ma Pleistocene | |
| Sample 74-1, LC-II pit, Lost Chicken site | Grebennikov V. V. (2010) | Sample from silt and peat between units D and E. Lost Chicken tephra dated at 2.6 +/- 0.45 Ma based on zircon fission-track. Unit C sediments just below LCT at Section 91-2 have a normal remanent magnetic polarity (Fig. 3), which suggests that LCT was deposited during the youngest normal subchron of the Gauss chron, that is, between 2.581 and 3.040 myr (Cande and Kent, 1995). The reversed magnetic polarity of Unit A likely means that it was deposited during the Kaena subchron (3.040–3.110 myr; C | siltstone | 2.588 - 1.806 Ma Pleistocene | |
