Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
The word that most adequately completes the fragment is Small because the rocks of the Grand Canyon do not span a wide span of geologic time.
<h3>What is geological time?</h3>
Geological time is a term to refer to the frame of reference used to represent the events of the history of the Earth and of life in chronological order. It establishes divisions and subdivisions of the rocks according to their relative age.
<h3>What is the Grand Canyon?</h3>
The Grand Canyon is a colorful and rugged gorge carved out by the Colorado River over millions of years in northern Arizona, United States.
The Canyon was created by the Colorado River, whose course undermined the land for millions of years. It is about 446 km long, has mountain ranges between 6 and 29 km wide and reaches depths of more than 1,600 m.
Additionally, nearly 2 billion years of Earth's history has been exposed as the Colorado River and its tributaries cut through layer after layer of sediment at the same time the Colorado Plateau was uplifted.
According to the above, it can be inferred that the Grand Canyon exposes a small portion of the earth's history because it exposes only about 1.7 to 2 billion years and the Earth is about 4.5 billion years old.
