100 Interesting Facts About Mesozoic Era

Facts About Mesozoic Era: The Mesozoic Era was a great epoch in the geological history of the Earth, which began 25.217 million years ago and ended 66 million years ago. This was preceded by the Palaeozoic era and followed by the Neolithic era which continues to this day. The Neolithic, the Mesozoic and the Palaeozoic era are three parts of the visible Eon. The medieval era is also called "the great era of reptiles" and "the great age of anglers" because it includes these animal and plant species.

All Triassic dinosaurs fall into one of two categories: Ornithischia (bird-hipped dinosaurs), and Saurischia (lizard-hipped dinosaurs).
The supercontinent Pangaea totally broke apart at the end of the Mesozoic Era. It was also the time when the climate changed drastically.
Dinosaurs in the Jurassic and Cretaceous periods often swallowed rocks. These rocks remained in the stomach and helped them grind up food.
In 1840, British geologist John Phillips proposed the name Mesozoic. The word Mesozoic is derived from the Greek language and means middle life.
Although the Mesozoic era is often famed as the age of dinosaurs, it wasn’t until the Jurassic period that dinosaurs became the most common large animals.
By the Middle Triassic Epoch, Pangaea began to break apart along with the recovery of mosquitoes, algae, and coral. In addition, crocodiles began to emerge.
The Mesozoic Era is one of the three eras in the Phanerozoic Eon, and the Phanerozoic Eon is one of four eons on the geological timescale of the planet Earth.
While most dinosaurs had cold-blood, much like the modern-day lizard, new evidence indicates that some dinosaurs were, more similar to warm-blooded like mammals.
With regards to diet, some dinosaurs were meat-eaters, also known as carnivores or theropods. They often preyed on other dinosaurs through hunting and scavenging.

Unique Facts About Mesozoic Era

Most dinosaurs were herbivores or plant-eaters. Dinosaurs such as Iguanodon, Triceratops, Stegosaurus, and Diplodocus had blunt, grinding teeth and cheek pouches.
Most dinosaurs were herbivores (plant-eaters). Dinosaurs such as Triceratops, Stegosaurus, Iguanodon, and Diplodocus even had blunt, grinding teeth and cheek pouches.
A single footprint can also provide insight into the kind of dinosaur that made it. A three-toed, sharp-clawed print means the dinosaur was likely a to be a carnivore.
By the Middle Triassic era, the Pangaea landmass began to break apart along with the recovery of mosquitoes, and algae. Also, reptiles such as crocodiles began to appear.
From a single dinosaur footprint, researchers can estimate the height of the dinosaur. A rough estimate of leg length is obtained by multiplying the print length by four.
Although famous for dinosaurs which dominated the era, the Mesozoic era animals also include many snake species, amphibians, turtles, mammals, birds, lizards and reptiles.
The sudden extinction event end of the Mesozoic era signaled the beginning of the Cenozoic period; this is the era we are in right now and is often called the age of mammals.
The word “dinosaur” was initially coined by a British paleontologist named Richard Owen in 1842 and originated from the Greek words dienos (“terrible”) and sauros (“reptile”).
It was during the Late Triassic period when Earth became warmer, enabling reptile species to evolve and dinosaurs began to emerge. It’s known as one of the foremost dinosaur eras.

Mind-Blowing Facts About Mesozoic Era

Amphibians developed respiratory mechanisms that allowed them to live both on land and in water. Furthermore, reptiles developed leathery and thick skin to adapt to warmer and drier climates.
During the Mesozoic era, the immense Panthalassa Ocean split into multiple basins. The Tethys Ocean separated Asia from the rest of the land and the Atlantic Ocean as we know it, started to form.
In 1912, geologist Alfred Wegener first proposed the theory of continental drift as the cause of the land mass separation from Pangaea to Laurasia and Gondwanaland into our modern day continents.
It was during the Early Triassic Epoch when the supercontinent Pangaea was a dry land mass. It was then populated by vertebrate life such as Euparkeria, Labyrinthodonts, Lystrosaurus, and tetrapods.
Each of the periods contained very different animal species. The Triassic time period was the era when both dinosaurs and mammals are believed to have evolved, as did the pterosaurs and ichthyosaurs.
In the 1800s, English geologist John Phillips first coined the term Mesozoic when he created the global geologic timescale. He correlated the sediments found around the world with specific time periods.

In the Mesozoic era, all of the world’s continents were joined together. The supercontinent Pangaea completely broke apart at the end of the Mesozoic era, and new continents were formed. This was a major event.
Not all dinosaurs lived together during the same period of time. The Stegosaurus lived around 150 million years ago, whereas the Tyrannosaurus Rex lived in the Late Cretaceous era, approximately 72 million years ago.
According to the International Commission on Stratigraphy, the start of the Mesozoic Era is called the Permian-Triassic boundary, when they found the type of extinct conodont (an eel-like creature) in Meishan, China.
The Mesozoic Era ended after the Cretaceous-Paleogene (K-Pg) extinction event. The Cretaceous-Paleogene (K-Pg) extinction event caused the extinction of the dinosaurs and paved the way for mammals to dominate the planet.
The Mesozoic Era was started after the Permian-Triassic extinction event. The Permian-Triassic extinction event was the largest extinction event in Earth’s history. Over 90% of marine species and 70% of land vertebrates became extinct.
The mass extinction from which the Mesozoic era emerged, is the largest known extinction event in the history of the world. However, the Mesozoic era also came to an abrupt end due to another mass extinction, 70% of life forms were destroyed.
The Mesozoic era began approximately around the time of the End-Permian extinction event, which wiped out 96 percent of all Earth's marine life and 70 percent of all terrestrial species on the planet. Life slowly began to return after this mass extinction.
The word ‘Mesozoic’ means middle animals, and the kind of animals around were very different from what came before or after this era. The middle animals of this time were dominated by dinosaurs, pliosaurs, plesiosaurs, pterosaurs and many other types of animals.
The Mesozoic era is also known as the Age of Reptiles, Age of the Dinosaurs and the Age of Conifers. It was known as the age of the dinosaurs because dinosaurs were so widespread and dominant, nothing was overtaking them, that's why it took a mass extinction to eradicate them.
Meteorologists believed that the geologic time of the Mesozoic era ended after the impact of an asteroid causing widespread extinctions. However, there are lots of different theories as to what may have caused the mass extinction event of dinosaurs at the end of the Cretaceous period.
The Cretaceous period has some of the most famous dinosaurs, such as Tyrannosaurus rex and Triceratops. It is also when flowers and flowering plants first evolved. The Cretaceous era was also when many dinosaurs died out and further extinctions occurred, which led to the end of this era.
The third and the longest period was the Cretaceous Epoch. For approximately 80 million years, a variety of dinosaurs and mammals began to evolve. It was during this time that Earth started to develop cold and warm climates on different poles. The ocean rose, resulting in expanded seaways.
About 200 million years ago, the Jurassic Period began with the rise of archosaurs. In addition, sauropods and theropods emerged in the forests filled with conifers. During the Late Jurassic Epoch, dinosaurs became more diverse as sea levels increased. Pangaea separated into two supercontinents known as Laurasia and Gondwanaland.
In terms of diet, some dinosaurs were meat-eaters also known as carnivores or theropods. They preyed on other dinosaurs through hunting and scavenging. Anatomically, carnivorous dinosaurs had strong and fast legs. They also had strong jaws, sharp teeth, and deadly claws. Tyrannosaurus rex, Velociraptor, Eoraptor, and Giganotosaurus were some of the meat-eating dinosaurs.
