Taxonomic list comments:short normal polarity chron of Opdyke et al. 1977 is explicitly shown as including this collecting unit; it almost certainly is chron C2n (1.77 - 1.95 Ma: Cande and Kent 1995), although there is a very small chance that it is chron C2r.1n, which otherwise does not appear in the section |
