many taxa actually described in Lindsay 1978 (see)
Jacobs cites dates of "5.21 to 6.25" Ma (K-Ar) on the Quiburis Fm.; Latorre et al. 1995 cite a date of "6.3 +/- 0.1 Ma" that appears to be based on correlation of site to chro C3An.2n by Lindsay et al. 1984, which equates with 6.27 - 6.57 Ma in time scale of Cande and Kent 1995
