An era of geologic time, from the end of the Paleozoic to the beginning of the Cenozoic (about 248-65 million years ago). Termed the era of middle life.
geological era (250-65mya), includes the Triassic, Jurassic and Cretaceous periods
The middle of the three Phanerozoic eras; it lasted from 245 Ma to 65 Ma.
'Middle life'. A geological era from 245 to 65 million years ago, and including the Triassic, Jurassic and Cretaceous periods.
An era of geological time, dating from about 250 to 65 million years ago (comprising the Triassic, Jurassic and Cretaceous periods).
Era between 248 and 65 MYA, to which the Triassic, the Jurassic and the Cretaecous belong.
1. the geologic era extending from the end of the Paleozoic era to the beginning of the Cenozoic era, dating form approximately 225 to 65 million years ago; included the Triassic, Jurassic, and Cretacious Periods. 2. the rocks formed during this era (Morris 1992). 3.)The era of geologic time from the end of the Paleozoic Era (225 million years ago) to the beginning of the Cenozoic Era (65 million years ago).

the Mesozoic ('middle life') Era was a span of geological time between 250 and 65 Ma. It included the Triassic, Jurassic and Cretaceous periods.
Era of geologic time 65-225 million years ago.
A Geological epoch from 230 to 65 million years ago
The third of the four Geologic Eras in which geologic time is divided. It extends from the end of the Paleozoic Era (about 230 million years ago) to the beginning of the Cenozoic Era (about 65 million years ago). The Mesozoic Era is subdivided into the Triassic, Jurassic, and Cretaceous periods.
from 230 million to 63 million years ago
The Age of Reptiles. Includes the Triassic, the Jurassic and the Cretaceous
era or period of geological time or sedimentary rock formation that began 225 million years ago at the start of the Triassic period and ended some 155 million years later at the end of the cretacious period, some 65 million years before present; the second or middle period of geological time, hence the name, from Greek misos 'middle' + zoe 'life' + -ic suffix denoting relationship.
An era of geologic time between the Paleozoic and the Cenozoic, spanning the time between 248 and 65 million years ago. The word Mesozoic is from Greek and means "middle life."
(see Geological Timescale)
the geological era which spans the Triassic, Jurassic and Cretaceous periods, from 245 to 65 million years ago. The name means middle life. See Geological Timescale.
(Secondary) geologic era ranging from 245 Ma to 65 Ma.
Divided into three time periods: the Triassic (245-208 Million Years Ago), the Jurassic (208-146 Million Years Ago), and the Cretaceous (146-65 Million Years Ago). Mesozoic means "middle animals", and is the time during which the world fauna changed drastically from that which had been seen in the Paleozoic. Dinosaurs, which are perhaps the most popular organisms of the Mesozoic, evolved in the Triassic, but were not very diverse until the Jurassic. Except for birds, dinosaurs became extinct at the end of the Cretaceous.
An era of geologic time, from the end of the Paleozoic to the beginning of the Cenozoic, or from about 248 to about 65 million years ago.
The era of geologic time above the Paleozoic and below the Cenozoic, approximately from 245 to 65 million years ago.
An era of time during the Phanerozoic eon lasting from 248 million years ago to 65 million ago. Derived from the Greek mesos "middle" + zoe "life".
This term literally means 'middle life'. This is based on the old division of geological time into three eras, the Palaeozoic, Mesozoic and Cenozoic or Cainzoic. This era is made up of three periods. The Triassic, Jurassic and Cretaceous. In terms of millions of years this period lasted from 248 million years to 65 million years (Ma). For more on the Mesozoic click here.
An era of geological time spanning 250-65Ma, including the Triassic, Jurassic and Cretaceous periods;
Geologic era that occurred from 245 to 65 million years ago.
The period of time, marked with the great expansion of life in the sea and on the land. The era stretched from 248 to 65 million years ago, and included the evolution and demise of the dinosaurs.
One of the grand divisions or eras of geologic time, following the Paleozoic and succeeded by the Cenozoic era, comprising the Triassic, Jurassic, an Cretaceous periods.
Era comprising the Triassic, Jurassic and Cretaceous, spanning 245-65Ma.
the geological era before the present (Cenozoic) era. It is characterized by the development of mammals, flying reptiles, birds, and flowering plants, and the appearance and death of dinosaurs. It comprises the Triassic, Jurrasic, and Cretaceous periods; the rocks fromed in this era. [AHDOS
The Mesozoic Era is one of three geologic eras of the Phanerozoic eon. The division of time into eras dates back to Giovanni Arduino, in the 18th century, although his original name for the era now called the 'Mesozoic' was 'Secondary' (making the modern era the 'Tertiary'). Lying between the Paleozoic and the Cenozoic, Mesozoic means 'middle animals', derived from Greek prefix meso-/μεσο- for 'between' and zoon/ζωον meaning animal or 'living being'.
