英文小作文：

The Cretaceous Period - A Time of Change

The Cretaceous period was a time of great changes in the Earth"s environment, marked by the extinction of many species and the rise of new ones. The Cretaceous-Tertiary boundary, which occurred at this time, marked the end of an era and the beginning of a new one, as well as the birth of many modern animals and plants. This period also saw the formation of many unique geological features, such as coal deposits and oil and gas fields, which are still used today for energy production. The Cretaceous period was also a time of exploration and discovery, as geologists and paleontologists studied the rocks and fossils of this era to better understand the history and evolution of life on Earth. I believe that this period is still very relevant today, as we continue to learn more about our planet and how it has changed over time.
