Here is a question about this article: The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.
What is the answer to this question: Oxygen from what kind of fossil were used to date the Hirnantian faunal stage?

So... brachiopods

Here is a question about this article: The remainder was the world-ocean known as Panthalassa ("all the sea"). All the deep-ocean sediments laid down during the Triassic have disappeared through subduction of oceanic plates; thus, very little is known of the Triassic open ocean. The supercontinent Pangaea was rifting during the Triassicespecially late in the periodbut had not yet separated. The first nonmarine sediments in the rift that marks the initial break-up of Pangeawhich separated New Jersey from Moroccoare of Late Triassic age; in the U.S., these thick sediments comprise the Newark Supergroup. Because of the limited shoreline of one super-continental mass, Triassic marine deposits are globally relatively rare; despite their prominence in Western Europe, where the Triassic was first studied. In North America, for example, marine deposits are limited to a few exposures in the west. Thus Triassic stratigraphy is mostly based on organisms living in lagoons and hypersaline environments, such as Estheria crustaceans and terrestrial vertebrates.
What is the answer to this question: Which sediements in the US are an indication of the break up of Pangaea?

So... Newark Supergroup

Here is a question about this article: In the United States and Canada, the film opened on 6 November 2015, and in its opening weekend, was originally projected to gross $7075 million from 3,927 screens, the widest release for a Bond film. However, after grossing $5.25 million from its early Thursday night showings and $28 million on its opening day, weekend projections were increased to $7580 million. The film ended up grossing $70.4 million in its opening weekend (about $20 million less than Skyfall's $90.6 million debut, including IMAX previews), but nevertheless finished first at the box office. IMAX generated $9.1 million for Spectre at 374 screens, premium large format made $8 million from 429 cinemas, reaping 11% of the film's opening, which means that Spectre earned $17.1 million (23%) of its opening weekend total in large-format venues. Cinemark XD generated $1.85 million in 112 XD locations.
What is the answer to this question: How much money did preview showings generate in the US and Canada?
****
So...
$5.25
