Are there any geological periods found on top of each other that have dinosaurs of that period with in them?

Asked by: Rodney Randall

What part of geologic time is represented by dinosaurs?

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.

What periods and eras have dinosaur fossils?

Dinosaurs appeared and disappeared during the Mesozoic Era, which lasted 186 million years and encompasses three periods: the Cretaceous, Jurassic, and Triassic.

Did people and dinosaurs live at the same time?

No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.

What is the difference between the Jurassic period and the Cretaceous Period?

The Jurassic period, from about 200 million to 145 million years ago, ushered in birds and mammals. And the Cretaceous period, from 145 million to 66 million years ago is known for its iconic dinosaurs, such as Triceratops, and pterosaurs such as Pteranodon.

When did dinosaurs appear on the geologic time scale?

When dinosaurs first appeared in the Triassic period (251.9 million to 201.3 million years ago), they roamed the supercontinent of Pangaea. But by the time the asteroid hit at the end of the Cretaceous period (145 million to 66 million years ago), the continents were in approximately the same place they are today.

How many dinosaur eras are there?

Dinosaurs lived during three periods of geological time – the Triassic period (which was 252-201 million years ago), the Jurassic period (about 201-145 million years ago) and the Cretaceous period (145-66 million years ago). These three periods together make up the Mesozoic Era.

Did Spinosaurus and T Rex live at the same time?

They Never Lived Or Existed Together



These two dinosaurs did not live together simultaneously, as the Spinosaurus existed before the T-rex did. The Spinosaurus existed during the Cretaceous period, while the T-rex lived during the upper Cretaceous period, between 67 to 65 million years ago.

What are the 3 eras of dinosaurs?

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.

What existed before dinosaurs?

The Permian is a geological record that began nearly 300 million years ago, almost 50 million years before the Age of the Dinosaurs. During the Permian the first large herbivores and carnivores became widespread on land. The Permian ended with the largest mass extinction in the history of the Earth.

What are the 4 geological eras in order?

The Precambrian, Paleozoic, Mesozoic, and Cenozoic Eras



The Geologic Time Scale is the history of the Earth broken down into four spans of time marked by various events, such as the emergence of certain species, their evolution, and their extinction, that help distinguish one era from another.

What does the Bible say about dinosaurs?

According to the Bible, dinosaurs must have been created by God on the sixth day of creation. Genesis 1:24 says, “And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.”

Who was the first human on Earth?

Homo habilis

The First Humans



One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.

What is the oldest human fossil?

Scientists determine age of some of the oldest human bones Some of the oldest human remains ever unearthed are the Omo One bones found in Ethiopia. For decades, their precise age has been debated, but a new study argues they’re around 233,000 years old.

Did Triceratops and T Rex live at the same time?

Triceratops lived in the Late Cretaceous period, around 68 to 65.5 million years ago. T. Rexes lived in the upper Cretaceous Period, around 67 to 65.5 million years ago. They were two of the last species of dinosaurs to exist before mass extinction.

Did T Rex and Velociraptors live at the same time?

The newly discovered dino, dubbed Acheroraptor temertyorum, was a two-legged meat-eater and close cousin of the Velociraptor. “We have had scanty evidence for more than a century that raptors lived with Tyrannosaurus rex until the end of the Cretaceous,” said Currie.

What percentage of geologic time did dinosaurs roam?

1 Answer. Thomas U. Kate M. Dinosaurs were around for (very roughly) 3.68% of the Earth’s current time span.

What major events in geologic history occurred during the Jurassic period?

During the Jurassic period, the supercontinent Pangaea split apart. The northern half, known as Laurentia, was splitting into landmasses that would eventually form North America and Eurasia, opening basins for the central Atlantic and the Gulf of Mexico.

Which geologic event occurred during Mesozoic Era?

This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you. It ended with a massive meteorite impact that caused a mass extinction, wiping out the dinosaurs and up to 80% of life on Earth.

What did the continents look like at the time of the dinosaurs?

All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor. The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.

What did the Earth look like when the dinosaurs were alive?

Quote from video: That the continents are all together lined up on a single side of the earth. With this enormous shoreline that extends all the way down from near the North Pole down to the South Pole.

What existed before dinosaurs?

The Permian is a geological record that began nearly 300 million years ago, almost 50 million years before the Age of the Dinosaurs. During the Permian the first large herbivores and carnivores became widespread on land. The Permian ended with the largest mass extinction in the history of the Earth.
