Mesozoic Era Questions and Answers
- 1.
What major event ended the Mesozoic Era?
- A.
The Earth stopped rotating.
- B.
The dinosaurs fell off the Earth.
- C.
A metior collided with the Earth, thus killing more than 90% of all life on earth.
- D.
The Earth froze over creating snow ball Earth.
- E.
All of the above.
Correct Answer
C. A metior collided with the Earth, thus killing more than 90% of all life on earth.Explanation
The correct answer is that a meteor collided with the Earth, causing the end of the Mesozoic Era. This event, known as the Cretaceous-Paleogene extinction event, occurred approximately 66 million years ago and resulted in the extinction of the dinosaurs and many other species. The impact of the meteor caused massive climate changes, including widespread wildfires, acid rain, and a global cooling effect, which led to the extinction of more than 90% of all life on Earth.Rate this question:

For how many years did the Mesozoic era last?
- A.
186 million years
- B.
150 million years
- C.
80 million years
- D.
100 million years
Correct Answer
A. 186 million yearsExplanation
The Mesozoic Era, often called the "Age of Reptiles," lasted approximately 186 million years. This era is divided into three major geological periods: the Triassic, Jurassic, and Cretaceous, spanning from about 252 million years ago to about 66 million years ago when it ended with the mass extinction event that wiped out the dinosaurs. This era is well-known for the dominance of dinosaurs and the significant evolutionary developments in other forms of life, including mammals and flowering plants. The durations given in the other options are not accurate for the length of the Mesozoic Era.Rate this question:

Which of these is a period?
- A.
Triassic
- B.
The 1920's
- C.
5 Epochs
- D.
Cambrien
- E.
All of the above
Correct Answer
A. TriassicExplanation
Triassic is the correct answer because it is a geological period that occurred approximately 252 to 201 million years ago, during the Mesozoic Era. It is known for the diversification of reptiles and the first appearance of dinosaurs. The other options, such as "The 1920's" and "5 Epochs," are not periods but rather time periods or quantities. Cambrien is misspelled and should be "Cambrian," which is also a geological period but not the correct answer in this case. Therefore, the correct answer is Triassic.Rate this question:

A group of animals that has a single hole on each side of the skull behind the eye is called ___________.
- A.
Synapsids
- B.
Plesiosaurs
- C.
None of the above
Correct Answer
A. SynapsidsExplanation
Synapsids are a group of animals characterized by having a single temporal fenestra, which is an opening in the skull behind each eye. This feature distinguishes them from other groups like diapsids, which have two openings. Synapsids include mammals and their extinct relatives. This group played a crucial role in the evolution of modern mammals, with early synapsids appearing in the late Carboniferous period and diversifying through the Mesozoic era. The term "synapsid" specifically refers to the unique skull structure that defines this evolutionary lineage.Rate this question:

The Mesozoic Era was drier than in the Paleozoic Era.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
During the Mesozoic Era, which lasted from about 252 to 66 million years ago, the climate was generally drier compared to the preceding Paleozoic Era. This change in climate was primarily due to the breakup of the supercontinent Pangaea, which led to the formation of large inland seas and deserts. The arid conditions during the Mesozoic Era favored the diversification and dominance of reptiles, including dinosaurs. Fossil evidence, such as the presence of evaporite deposits and desert sandstones, supports the notion that the Mesozoic Era was indeed dryer than the Paleozoic Era.Rate this question:

The Mesozoic Era began when the upheavals of the Permian Extinctions ended.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The Mesozoic Era began approximately 252 million years ago, following the end of the Permian Period, which was marked by the largest mass extinction event in Earth's history, known as the Permian-Triassic extinction event. This catastrophic event led to the extinction of about 90% of marine species and 70% of terrestrial vertebrate species. The end of these upheavals and the vast ecological vacancies created by the extinction allowed new life forms to evolve and diversify, marking the beginning of the Mesozoic Era, often referred to as the "Age of Reptiles." This era is notable for the rise and dominance of dinosaurs, along with significant evolutionary developments in other flora and fauna.Rate this question:

At the start of the Mesozoic, all of Earth’s continents were joined together into the supercontinent of _____________.
- A.
North America
- B.
Europe
- C.
Pangea
- D.
Asia
Correct Answer
C. PangeaExplanation
At the start of the Mesozoic Era, all of Earth's continents were indeed joined together to form the supercontinent known as Pangea. This vast landmass played a crucial role in the environmental and evolutionary dynamics of the time. Pangea began to gradually break apart during the Mesozoic, leading to the formation of the continents as we know them today. The breakup influenced ocean currents, climate, and the spread of animal and plant species, significantly impacting the evolutionary paths of many organisms during the Mesozoic.Rate this question:

What was the name of the supercontinent during the Mesozoic Era?
- A.
Super Asia
- B.
Super Europe
- C.
Pangea
- D.
Eurasia
- E.
All of the above
Correct Answer
C. PangeaExplanation
During the Mesozoic Era, the supercontinent was called Pangea. This massive landmass included all of Earth's continents combined into one large supercontinent, which existed during the late Paleozoic and early Mesozoic eras before it began to break apart. The breakup of Pangea led to the formation of the continents as they are positioned today. This process significantly influenced global climatic conditions, ocean patterns, and the evolutionary trajectories of life on Earth. The terms "Super Asia," "Super Europe," and "Eurasia" do not refer to the supercontinent configuration during the Mesozoic Era.Rate this question:

There are __ major epochs in the Mesozoic era.
Correct Answer
3, threeExplanation
The Mesozoic Era, often called the Age of Dinosaurs, is a significant geological time frame that lasted from about 252 to 66 million years ago, spanning approximately 186 million years. This era is classically divided into three major periods: the Triassic, Jurassic, and Cretaceous. Each period is marked by unique biological and geological developments. The Triassic Period saw the emergence of the first dinosaurs and mammals, alongside the early conifers. During the Jurassic Period, dinosaurs proliferated and became the dominant terrestrial vertebrates, and the first birds appeared. The Cretaceous Period was notable for the introduction of flowering plants and ended with the mass extinction of the dinosaurs, paving the way for mammals to become the dominant land animals. This era is critical in understanding the evolutionary history of life on Earth, detailing the rise of dinosaurs and their sudden demise, which triggered the rise of mammals.Rate this question:
- 10.
The era after the Mesozoic Era was called ____________.
- A.
Cenozoic Era
- B.
Paleozoic Era
- C.
Cretaceous Era
- D.
None of the above
Correct Answer
A. Cenozoic EraExplanation
The correct answer is Cenozoic Era. The Cenozoic Era is the geological era that followed the Mesozoic Era, also known as the Age of Dinosaurs. It began about 66 million years ago and continues to the present day. During the Cenozoic Era, mammals diversified and became the dominant land animals, and the Earth's climate and continents underwent significant changes. This era is often referred to as the "Age of Mammals" due to the rise and diversification of mammals during this time.Rate this question:
