Members
- Telegraph Creek – The lowest member, it represents mudstone deposited just offshore in a marine setting. It has produced the ammonite index fossil Desmoscaphites bassleri (Payenberg et al. 2002), which has an age of ~84.5 Ma.
- Virgelle – Overlying the Telegraph Creek Member, it is a massive cliff-forming yellow to white sandstones. It was deposited in a shoreface environment, including beach, etc. (Payenberg et al. 2002).
- Deadhorse Coulee – Consists of shales, siltsones, sandstones, and coal beds. The Member was deposited in rivers, floodplains and swamps. Most of the vertebrate fossils come from this member.
There are some dinosaur remains from the Formation, but these are not very well known. A more concerted effort at locating specimens would undoubtedly produce many new taxa.

Famous quotes containing the word members:
“Religion is the centre which unites, and the cement which connects the several parts of members of the political body.”
—George Berkeley (1685–1753)
“I rejoice that horses and steers have to be broken before they can be made the slaves of men, and that men themselves have some wild oats still left to sow before they become submissive members of society. Undoubtedly, all men are not equally fit subjects for civilization; and because the majority, like dogs and sheep, are tame by inherited disposition, this is no reason why the others should have their natures broken that they may be reduced to the same level.”
—Henry David Thoreau (1817–1862)
“A family with the wrong members in control—that, perhaps, is as near as one can come to describing England in a phrase.”
—George Orwell (1903–1950)
