At 52.38 when they jump in the cave hole, neither of them is holding a backpack. At 53.10 he's walking with the backpack.
When the asteroid is viewed from the planet, it is glowing dark orange. Asteroids do not glow unless heated by friction such as that from atmospheric entry. In space, there is no such friction and the asteroid should be a dark rock and undetectable by eyesight. Solar wind can give a comet a tail but it will not make asteroids glow.
At exactly 21:48 Mills is walking through some pine trees and the tree on his left has a red spray paint marking on it.
The trailer reveals that these marks were made by Mills. However the scene was scrapped. (He later uses this powder substance to draw a map in it.)
The booms of the smaller asteroids hitting sound at the same time as the impact. However, they appear to be at least a mile away so the impact sound should be delayed by several seconds.
The booms are not caused by impact. They are sonic booms caused by the meteor fragments traveling through air far in excess of the speed of sound and are heard before the meteorites hit the ground.

The technology used to track the escape vessel calculates distance in kilometers. This would not be possible because the metric system is very specific to Earth and established based on measurements taken on Earth. The meter was originally defined in 1791 as one ten-millionth of the distance from the equator to the North Pole along a great circle. However, the very fact that it (and Mills) speak English is unrealistic. One has to assume that the language is being translated, and the distance units along with it.
The asteroid impact depicted in the movie happened slightly over 66 million years ago, not 65 as implied by the title. However, dating of prehistoric events is an imprecise science, and the number 65 is etched into popular culture. Since the film is set in a fictional world with alien humans and fantasy dinosaurs with little basis in reality, perhaps the incorrect date was a deliberate decision.
The creatures aren't prehistoric, it's a foreign planet and for that planet the creatures are the current history inhabitants.
Many of the dinosaur types shown went extinct before the last phase of the Cretaceous. Some are in fact proto-dinosaurs that went extinct in the Permian or the Triassic, which are separated from T-Rex by more millions of years than separate T-Rex from humans (see trivia).
