Many fossils remain buried
Rocks contain the history of life...
Btw the animal ones don't count i think cuz fossils can be anything like teeth, bones or anything not just animals it can be formed by leaves as well so just for extra guidance i believe the ones that state animals are probably not the options to choose due to the fact that fossils are not just living organisms they're anything that has been buried and decomposed over many years and layers of sediments cover it over many years compression may alter the shape of the fossil aswell!
Hope that extra info helps for a bit of guidance!
East of the Rocky Mountains is the so called Midwest region in North America. This vast region is mostly consisted of lowlands covered with grasses, and they are bordered with mountain ranges on both the east and the west, which prevents the maritime influence.
Because of this natural barriers, this region has mostly continental air masses influencing its climate. In the colder period of the year they are continental polar air masses, forming over Canada and moving southwards. In the warmer period of the year they are continental tropical, forming in the southern part of this region and moving northwards.
This type of air masses bring in very hot and dry summers, and very cold and snowy winters.
