About 200 million years ago, as the Triassic Period came to a close,1. What is the main topic of this passage?
many species of animals disappeared from the face of the Earth. Scientists
previously believed that the series of extinctions happened over
a period of 15 to 20 million years. Recent discoveries in Nova Scotia
5 suggest, however, that the extinctions may have happened over a much
shorter period of time, perhaps less than 850,000 years.
Evidence for a rapid extinction of species at the end of the Triassic
Period is found in the McCoy Brook Formation along the Bay of Fundy
10 in Nova Scotia. Fossils found in this formation indicate a rapid
disappearance of species rather than a slow and gradual change over
time. One explanation for a relatively sudden extinction at the end
of the Triassic may be that a large meteorite struck the earth at
the time and is responsible for a 70- kilometer hole nearby. If geologists
15 and other researchers can find evidence, such as shocked quartz in
the rock formations, that a meteorite did strike the earth, it would
give more credence to the theory of rapid Triassic extinctions. It
is possible, however, that even if a rapid extinction happened in
and around Nova Scotia, it did not necessarily occur in the rest
20 of the world.
