Fossils and Age
Very limited detailed descriptions of the Haynesville Shale indicated that it is fossiliferous. The reported fossils include unidentified coccoliths, bivalves, gastropods, and calcispheres. Both stratigraphic relationships and a nannofossil (ccocolith) assemblage described from it indicates that it is Kimmeridgian, 151 to 157 million years old, in age.

Famous quotes containing the words fossils and/or age:
“You can hardly convince a man of an error in a life-time, but must content yourself with the reflection that the progress of science is slow. If he is not convinced, his grandchildren may be. The geologists tell us that it took one hundred years to prove that fossils are organic, and one hundred and fifty more to prove that they are not to be referred to the Noachian deluge.”
—Henry David Thoreau (1817–1862)
“Beautiful credit! The foundation of modern society. Who shall say that this is not the golden age of mutual trust, of unlimited reliance upon human promises? That is a peculiar condition of society which enables a whole nation to instantly recognize point and meaning in the familiar newspaper anecdote, which puts into the mouth of a distinguished speculator in lands and mines this remark:M”I wasn’t worth a cent two years ago, and now I owe two millions of dollars.””
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
