Answer:
The Marsupials would be extinct as they wont be able to migrate to South America and Australia.
Explanation:
- If the plate tectonics would be in a position as they are in today then the marsupials population that is found today in Australia and other countries would not have been possible as the plate tectonics would not allow them to migrate to these places.
- Even if they would migrate to another pace they would not survive as these creatures don't know how to travel longer distances and would eventually die of starvation.
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.
