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:
“The members of a body-politic call it the state when it is passive, the sovereign when it is active, and a power when they compare it with others of its kind. Collectively they use the title people, and they refer to one another individually as citizens when speaking of their participation in the authority of the sovereign, and as subjects when speaking of their subordination to the laws of the state.”
—Jean-Jacques Rousseau (17121778)
“...wasting the energies of the race by neglecting to develop the intelligence of the members to whom its most precious resources must be entrusted, already seems a childish absurdity.”
—Anna Eugenia Morgan (18451909)
“[T]here is no breaking out of the intentional vocabulary by explaining its members in other terms.”
—Willard Van Orman Quine (b. 1908)
