What era would you find the Cretaceous period?

The Cretaceous Period was the last and longest segment of the Mesozoic Era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic Period about 145 million years ago to the Cretaceous-Paleogene (K-Pg) extinction event dated at 66 million years ago.

What were the major geologic events of the Cretaceous period?

During the Cretaceous, accelerated plate collision caused mountains to build along the western margin of North America. As these mountains were rising, the Gulf of Mexico basin subsided, and seawater began to spread northward into the expanding western interior. Marine water also began to flood from the Arctic region.

What geologic era had Dinosaurs?

The 'Age of Dinosaurs' (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods).

Is the Cretaceous Period Prehistoric?

To put these geologic periods in the proper context, bear in mind that the Triassic, Jurassic, and Cretaceous don't cover all of prehistory, not by a long shot. ... It's only after all that that we reach the Mesozoic Era (250-65 million years ago), which includes the Triassic, Jurassic and Cretaceous periods.

What is a Cretaceous era?

Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. 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).

What happened in the Paleocene era?

The Paleocene Epoch began and ended with two great events: the Cretaceous–Tertiary extinction event and the Paleocene–Eocene Thermal Maximum. The continents moved closer to their current positions, dinosaurs were wiped out, and mammals and birds greatly diversified. What a great time in Earth's history!

What happened during the late Cretaceous period?

The Cretaceous–Paleogene extinction event was a large-scale mass extinction of animal and plant species in a geologically short period of time, approximately 66 million years ago (Ma).

What was the dinosaur era?

Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared.

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

In the Jurassic, both plant-eating and meat-eating dinosaurs grew enormous. The world broke into two continents. In the Cretaceous, flowering plants and many insects evolved. Duck-billed dinosaurs and horned dinosaurs developed.

What age are amphibians?

The Carboniferous Period is also known as the Age of Amphibians. It is the fifth of six geologic periods that together make up the Paleozoic Era. The Carboniferous Period is preceded by the Devonian Period and followed by the Permian Period.

Where have fossils from the Cretaceous period been found?

The most extensive Cretaceous dinosaur fossil record comes from Big Bend National Park (Texas), where rocks from the Late Cretaceous hold fossils similar to those from southern Canada, Montana, and nearby areas.

What was the Cretaceous period known for?

The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land.

During which era and period did worms first appear in the fossil record?

It lived 555 million years ago during what geologists term as the Ediacaran Period - the time in Earth history when life started to become multi-celled and much more complex. The discovery started with tiny burrows being identified in rocks in Nilpena, South Australia, some 15 years ago.
