The Mesozoic Era is divided into three periods: the Triassic, Jurassic, and Cretaceous. This era, often referred to as the "Age of Reptiles," lasted from about 252 to 66 million years ago and is characterized by the dominance of dinosaurs and the emergence of mammals and birds. Each period features distinct geological and biological developments, marking significant evolutionary milestones.
The next term in the sequence "Era, Period" is "Epoch." This sequence reflects the hierarchical classification of geological time, where an era is subdivided into periods, and periods can further be divided into epochs. Thus, after "Period," the logical progression leads to "Epoch."

It is the Mesozoic Era which is divided into 3 periods - the Triassic, the Jurassic and the Cretaceous.
The Phanerozoic Eon is divided into three major eras: the Paleozoic Era, the Mesozoic Era, and the Cenozoic Era. The Paleozoic Era is further divided into six periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The Mesozoic Era is divided into three periods: Triassic, Jurassic, and Cretaceous. The Cenozoic Era is divided into two periods: Paleogene and Neogene.
there are different periods in each era. In the Cenozoic era, there are 2 periods, Quaternary and Tertiary. Mesozoic era has 3 periods, Cretaceous, Jurassic, and Triassic. Paleozoic has 7 periods, Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. Precambrian is just the present, no time periods in it.
The Mesozoic Era is divided into three periods: the Triassic, Jurassic, and Cretaceous periods. These periods are further divided into epochs, which are smaller subdivisions of time.
There were three geological periods in the Mesozoic Era(251 - 65Ma).The Triassic Period(251 - 199Ma),the Jurassic period(199 - 145Ma) &the Cretaceous Period(145 - 65Ma).
The Mesozoic Era is divided into three periods: the Triassic, Jurassic, and Cretaceous periods. The Triassic period occurred from about 252 million years ago to 201 million years ago. It was a time of significant evolutionary changes, including the diversification of reptiles and the rise of the dinosaurs.
Eras divide into periods and periods divide into epochs. The Palaeozoic Era is composed of the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods (in that order). The Mesozoic Era is divided into the Triassic, Jurassic and Cretaceous periods. The Cenozoic Era is divided into the Tertiary and Quaternary periods. The Tertiary period is divided into the Palaeocene, Eocene, Oligocene, Miocene and Pliocene epochs while the Quaternary period is divided into the Pleistocene and Holocene epochs. Note that eras are not the longest lengths of time. Eras may compose longer stretches of time known as eons/aeons.
Hockey is divided into 3 periods to allow players to rest and strategize between periods, ensuring fair competition and maintaining the pace of the game.
The Age of Reptiles was the Mesozoic Era. The three periods were the Triassic, Jurassic, and Cretaceous.
The Cenozoic era on the geologic time scale is divided into periods and epochs. This era includes periods such as the Paleogene and Neogene, which are further divided into epochs like the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene.
Stone age
The three periods of Roman history were the monarchy, the republic and the principate. They were divided this way by the types of government in those periods.
