Which geologic event occurred during the Mesozoic Era quizlet?
What was the most significant geologic event of the Mesozoic quizlet?
The assembly of supercontinent Pangaea. This significant geologic event began in the Triassic Period of the Early Mesozoic Era: The break-up of supercontinent Pangaea.
Which came first Jurassic or Cretaceous Period?
The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and was succeeded by the Paleogene Period (the first of the two periods into which the Tertiary Period was divided).
During which geologic era did life first appear on land?
Archaean
The middle era of Precambrian time, spanning the period between 3800 and 2500 million years ago is called the Archaean, meaning ancient. Life arose on Earth during the early Archaean, as indicated by the appearance of fossil bacteria in rocks thought to be about 3500 million years old.

The ‘Age of Dinosaurs’ (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods.

Late Cretaceous
T. rex lived at the very end of the Late Cretaceous, which was about 90 to 66 million years ago.

What was one geologic change in the Mesozoic Era?
At the outset of the Mesozoic, all of Earth’s continents were joined together into the supercontinent of Pangea (see the map of the Early Triassic). By the close of the era, Pangea had fragmented into multiple landmasses. The fragmentation began with continental rifting during the Late Triassic.
Which of the following first appeared during the Mesozoic?
The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.
