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:
“If the education and studies of children were suited to their inclinations and capacities, many would be made useful members of society that otherwise would make no figure in it.”
—Samuel Richardson (1689–1761)
“What’s the greatest enemy of Christianity to-day? Frozen meat. In the past only members of the upper classes were thoroughly sceptical, despairing, negative. Why? Among other reasons, because they were the only people who could afford to eat too much meat. Now there’s cheap Canterbury lamb and Argentine chilled beef. Even the poor can afford to poison themselves into complete scepticism and despair.”
—Aldous Huxley (1894–1963)
“[T]here is no breaking out of the intentional vocabulary by explaining its members in other terms.”
—Willard Van Orman Quine (b. 1908)
