Maybe, but probably not. If people and animals can live in oxygen rich or poor environments, why couldn't a dinosaur? Life is highly adaptable, so
while it might be with with limited functionality, it could go on. Currently, oxygen makes up about 21% of the air we breath. Estimates put the oxygen
levels as varying through the Mesozoic Era. Some say it was higher throughout, some say it was lower at the start and higher at the end, some say it
was higher in the Triassic, lower in the Jurassic,and higher again in the Cretaceous. I was unable to find a clear answer to present.

The person who posted before asking a similar question was doing so under the guise of pseudo-scientific Bible ramblings that were developed during
the 1880s to attempt to give a scientific explanation for the Great Flood myths. The "water canopy" hypothesis states that before the Great Flood,
all the water was stored in the Earth's atmosphere. Here
that. My favorite explanation is this one.
Air can hold, at most, 55 grams of water vapor per cubic meter. In contrast, liquid water is at a density of 1,000,000 grams per cubic meter. The
ratio of the two numbers is 1:18,000. Therefore, a flood of 1 mile thickness (which would cover only 1/5 of Mount Everest), would require 18,000 miles
of canopy. Besides the problem of gravity (which would bring the whole thing down), such a thick layer of water vapor would completely block any light
from the Sun from reaching the earth.
Even a canopy of the equivalent of only 40 feet of liquid water would double the earth's atmospheric pressure, which would kill many animals,
including humans. This pressure would also increase the temperature on the earth to a scorching 220°F. Most animals and plants do not survive long at
Another problem is getting the water out of the atmosphere and onto the ground without cooking everything on the earth. Each gram of water vapor that
condenses to a liquid releases 539 calories of heat. For a vapor canopy to produce a global water layer of only 40 feet deep, 6.22 x 1021 grams of
water would release 3.35 x 1024 calories, raising the temperature of the earth to 810°F. Such a scenario would definitely kill all life on earth, but
would produce a tremendous air conditioning problem for Noah. And a 40 feet deep flood would certainly not be global.
