During the Cretaceous period, the Earth’s continent experienced a severe drift, and the sea level line at that time was also the highest in history. After an explosive growth, the Cretaceous life finally disappeared in a catastrophic upheaval.
The Cretaceous began at 144.1 million years ago. At that time, the Pangu continent had split, and the two major continents of the two continents struck and shattered in turn, forming the continent today. This continental drift caused major changes in the Earth’s climate, and caused the sea level line to be more than 200 meters higher than it is now. The ocean is full of microbes. Microwave shells gather on the broad shoals of the sea floor. Chalk. The word “chalk” has been played in Latin and has since become the name of the era.
Unlike the Triassic or Jurassic, the Cretaceous is somewhat similar to the world as it is now known. Flowering plants are likely to have appeared in the Late Jurassic or Early Cretaceous, but the Cretaceous really entered its heyday. These plants include the earliest hardwood trees, and slowly, hardwood trees have replaced conifers in many parts of the world. As flowering plants evolved, pollen-borne insects also evolved, such as bees. This very successful companionship was born and continues to this day.
