Abstract
A new genus Vincentdromia accommodates Vincentdromia americana (Roberts, 1956) new combination. The age for the species is revised to earliest Eocene (Ypresian) from Eocene (Roberts, 1956) or Paleocene (Schweitzer et al., 2012), based upon reinterpretations of microfossil zones and updates to the International Chronostratigraphic Chart. Eriosachila orri Schweitzer and Feldmann, 2000, is reported for the first time from Eocene rocks of California. Newly referred specimens expand the range of morphological variation, the age, and the geographic range for Stevea martini Feldmann et al., 2014.
