Which era is often referred to as the "Jurassic Park" era?

The Mesozoic Era is commonly referred to as the "Jurassic Park" era due to its association with the Jurassic Period, which is well-known for the dominance of dinosaurs. During this era, which spanned from approximately 252 to 66 million years ago, the Earth experienced significant geological and biological changes, leading to the rise and fall of many species, particularly dinosaurs. The Jurassic Period is highlighted by the diverse range of dinosaur species that roamed the Earth, which has captivated public imagination, especially through popular culture, such as the "Jurassic Park" franchise.

This era is characterized by the appearance of various types of dinosaurs, the first mammals, and the development of lush vegetation, making it a key period in Earth's history for understanding prehistoric life. In contrast, the Paleozoic Era predates the dominance of dinosaurs, the Cenozoic Era follows their extinction, and the Quaternary Period is much more recent, focusing on the appearance of mammals and humans. Thus, the reference to the "Jurassic Park" era is specifically rooted in the Mesozoic, particularly in its Jurassic Period.
