Time Periods

The Permian Period is a geologic period corresponding to the last subdivision of the Paleozoic Era. It began 299.9 million years ago and ended approximately 251 million years ago. Permian is named after the region of Perm located in Russia, where rocks from this period were first studied. The period was named back in 1841 […]

The Carboniferous Period is a geologic period of the Paleozoic Era. It began 358.9 million years ago and lasted until the beginning of the Permian Period 289.9 million years ago. The Carboniferous is most popular for its abundance of fossilized plant remains that formed extensive coal deposits in various locations all over the world. The

The Devonian Period is a geologic period of the Paleozoic Era that began approximately 419.2 million years ago and ended 358.9 million years ago. The period is named after Devon, a county in southwestern England where rocks from this period were first studied. Commonly referred to as the “Age of Fishes,” the Devonian Period is

The Cambrian Period is the first period of the Paleozoic Era, marking the beginning of the Phanerozoic Eon. The period lasted about 55 million years between 541 million and 485.4 million years ago.  It is named after “Cambrian,” the Latin name for Wales, where rocks corresponding to that period were first identified in Britain.

The current era of geologic time is called the Cenozoic Era. It began 66 million years ago after the end of the Mesozoic Era. The Cenozoic Era is the last of the three eras of the Phanerozoic Eon and is the shortest so far. The term “Cenozoic” means “new life.” The name was proposed by

The Paleozoic Era is the first of the three geologic eras that make up the Phanerozoic Eon. The term “Paleozoic” means “ancient life, ” and it was coined in 1838 by British geologist Adam Sedgwick. The era began about 541 million years ago and ended about 251.9 million years ago, making it the longest era

The Triassic Period is the first period of the Mesozoic Era. It spanned over a period of 51 million years, starting from the end of the Permian Period of the Paleozoic Era (about 252 million years ago) till the beginning of the Jurassic Period (about 201 million years ago). The Triassic Period was named after

The Earth’s history is split into various periods and chapters, all of which represent unique eras, happenings, and creatures. One of the most famous of all these periods is the Jurassic Period, primarily for its diversity and the existence of dinosaurs. The Jurassic period marked the end of the Triassic and predated the Cretaceous, all

Also called the “Age of the Reptiles,” the Mesozoic Era is the earth’s second-to-the-last era of geological history that lasted from approximately 252 to 66 million years ago. This era was called the Age of the Reptiles because of the earth’s abundance of reptiles at the time, particularly dinosaurs that ruled the earth and sky.
