Vaughn conducted paleontologic
studies and his conclusions were that the marl that existed below the Ostrea georgiana bed should exist in the lower portion of the Eocene's Claiborne group (Vaughn 1901).

In 1972 Carl Sagan and George Mullen realized that because of this "faint young Sun," the early Earth should have been completely frozen over--but geologic and paleontologic
evidence shows it wasn't.
However, evidence contradicting this hypothesis based on genetic, paleontologic
and morphological data was almost immediately produced (Dowling et al.

Therefore, given that the oldest paleontologic
records of Gramineae and Cyperaceae go back to Paleocene and Eocene (Cronquist, 1993), and that the greatest diversification of Gramineae species would have occurred during Oligocene and Miocene (Jacobs et al.
