TRIASSIC SYSTEM Meaning and
Definition
-
The Triassic system is a geologic time period that spans from approximately 251 million to 199 million years ago. It is a major division of the Phanerozoic Eon and the Mesozoic Era. The name "Triassic" is derived from the Latin word "trias," meaning three, because it is characterized by the presence of three clearly defined rock layers or series: Lower Triassic, Middle Triassic, and Upper Triassic.
During the Triassic period, the Earth experienced significant changes following the mass extinction event that marked the end of the Permian period. The system is known for its diverse flora and fauna, particularly the emergence and dominance of reptiles. It is often referred to as the "Age of Reptiles" as reptilian life forms adapted and flourished, including early dinosaurs, crocodiles, turtles, and flying reptiles.
The Triassic system is further characterized by the presence of distinctive sedimentary rocks, including sandstones, mudstones, and limestone. Fossil remains found within these rocks provide valuable insights into the evolution and geological history of the time. Additionally, the system is marked by the formation of several notable geological features such as mountains and rift zones.
Overall, the Triassic system is a critical period in Earth's history, linking the previous mass extinction event to the later diversification of life during the Jurassic and Cretaceous periods. It represents a transitional time, both biologically and geologically, as the Earth recovered and new ecosystems began to emerge.

Etymology of TRIASSIC SYSTEM
The word "Triassic" is derived from the Latin prefix "tri-", meaning "three", and the word "assic", which comes from the Latin "assus", meaning "to roast" or "baked". This name was given to the geological system because it was believed to represent the third period of the Mesozoic Era when it was first recognized and classified. The Triassic system is a division of geological time that spans from approximately 251 million years ago to 201 million years ago.
