What was the Triassic Cretaceous in history, and the glacial age?

The order from far to near is Cambrian, Triassic, Jurassic, and Cretaceous.

The Cambrian period is the beginning of the Phanerozoic, about 100 million years ago. The former is the Neoproterozoic Ediacaran and the latter is Ordovician.

The Triassic (English: Triassic), a geological epoch between 100 million BC and 200 million BC, is located between the Permian and Jurassic periods, and is the first epoch of the Mesozoic Era. The beginning and end of the Triassic were each marked by an extinction event.

The Jurassic is a geological epoch between the Triassic and Cretaceous periods, ranging from 199.6 million BC (600,000 years with an error of 600,000 years) to 145.5 million years (with an error of 4 million years).

The Cretaceous Period is the last epoch of the Mesozoic Era in geological time, beginning 100 million years ago and ending 66 million years ago, over a period of 79 million years. It is the longest phase of the Phanerozoic.

Paleontological discoveries.

On September 15, 2014, experts from Zigong Dinosaur Museum and China University of Geosciences conducted a field investigation and study on the dinosaur footprints found in Xinyang and Longjing villages in Dashi Township, Xuyong County, Luzhou City, and concluded that there were three types of dinosaur footprints in the Cretaceous period about 100 million years ago.

From front to back, it is Triassic, Jurassic, and Cretaceous.

The Triassicperiod is the first epoch of the Mesozoic Era. It began from 100 million years ago and lasted for about 50 million years.

The Jurassic period is the second epoch of the Mesozoic Era, which began 100 million years ago and ended in 100 million years, with a total of 68 million years.

The Cretaceous period is the last epoch of the Mesozoic Era, which began 100 million years ago and ended 65 million years ago, with 70 million years in between. Both the inorganic and organic worlds underwent important changes during the Cretaceous period.

Jurassic features:

Throughout the Jurassic period, most of the period was warm and humid. The abundant forest vegetation at that time formed the abundant coal resources of present-day Australia and Antarctica. Although there were localized arid areas at that time, the vast majority of Pangea was a lush oasis.

The biota of the Laoya continent and the Gondwana continent in the south are still unique in many respects, and the fauna has a more intercontinental color.

1. The geological age from ancient times to the present is: Cryptozoic Eon (now known as Precambrian Supereon) and Phanerozoic Eon.

2. The Cryptozoic has now been subdivided into the Phertozoic, Archean, and Proterozoic.

3. Phanerozoic is divided into: Paleozoic, Mesozoic, and Cenozoic.

4. The Paleozoic Era is divided into: Cambrian, Ordovician, Silurian Period, Devonian, Carboniferous, and Permian.

5. The Mesozoic Era is divided into: Triassic, Jurassic, and Cretaceous.

6. The Cenozoic is divided into: Paleogene, Neogene and Quaternary.

We currently belong to the latest era of the Cenozoic Era - the Quaternary Period.

Sinian, Cambrian, Ordovician, Silurian period, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, Paleogene, Neogeny, Quaternary. Now belongs to the Quaternary period.

1. Definition of the Quaternary.

The Quaternary refers to the most recent era of 2.6 million years, and the Quaternary is the shortest and closest era in geological history, but there are too many turbulences and twists and turns.

2. Characteristics of the Quaternary.

The Quaternary was characterized by the alternation of glacial and interglacial periods, and the emergence of human beings. One of the most important factors in the turmoil and ups and downs of the Quaternary was climate change.

The mysterious cycle of nature has caused the arid and cold ice ages to overlap with the warm and humid interglacial periods, and the sea water has risen and fallen, and the coastal zone has also staged the legend of the vicissitudes of the sea four times.

The Quaternary is the latest epoch of the Cenozoic, including the Pleistocene and Holocene. The lower limit is mostly dated to 2.58 million years ago. During the Quaternary period, the biological world evolved to its modern appearance.

The primate has completed the evolution from ape to man. The pre-Quaternary period is the Neogene. It started about 2.6 million years ago and continues to this day.

There are also Ordovician, Silurian period, Tertiary period, Carboniferous period, Quaternary period when humans appeared, and now in the 21st century.

Historical order: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous.

Tertiary Quaternary.

There are: Iron-Age, Stratigraphic Invasion, Orogenic Age, Consolidation Period, Caprock Age, Extensional Period, Narrow Zone, Extensional Period, Extensional Period, Ediacaran Period (also known as Sinian, Wende), Cambrian, Ordovician, Silurian Period, Devonian, Carboniferous, Permian (Jurassic, Cretaceous and Triassic), Paleogene, Neogene, Quaternary. Qingbai Kouji?

When mankind appeared, the Quaternary period is now the 21st century.

The Iron Age, the Ediacaran Period, the Orogenic Period, and the Consolidation Period ......

Cambrian, Permian, Triassic, Jurassic, Cretaceous, Devonian, what else? What is the Cambrian, Permian, Triassic, Jurassic, Cretaceous, Devonian, and what else does it belong to? Now is what it belongs to.

Plutozoic (4.638 billion years ago):

Hermitage, Protozoic, Dionysian, and Yuhai generations.

Archean (3.825 billion years ago):

Archean, Archean, Mesoarchan, Neo-Archean.

Proterozoic (2.5 billion years ago):

Paleoproterozoic: Iron Formation, Layer Invasion, Orogenic and Consolidation.

Neoproterozoic: Stretching, Glacing, Ediacaran.

The geological chronology of China is like this:

Archean (4.025 billion years ago).

Proterozoic (2.5 billion years ago):

Paleoproterozoic: Wutai Period, Hutuo Period.

Mesoproterozoic: Great Wall Period, Jixian Period.

From front to back, it is Triassic, Jurassic, and Cretaceous.

The Triassic is a geological epoch between 100 million BC and 200 million BC, which is located between the Permian and Jurassic periods, and is the first epoch of the Mesozoic Era. The beginning and end of the Triassic were each marked by an extinction event. Although the rock markings of this period are very clear and clear, the exact time of their beginning and end cannot be determined with great precision, as in other ancient geological epochs.

The error is plus or minus millions of years.

The Jurassic is a geological epoch between the Triassic and Cretaceous periods, ranging from 199.6 million BC (600,000 years of error) to 145.5 million years (4 million years of error). The Jurassic is the second epoch of the Mesozoic Era, which began with the Triassic-Jurassic extinction event. Although the rock markings of this period are very clear and clear, the exact time of their beginning and end cannot be determined with great precision, as in other ancient geological epochs.

The Cretaceous is the last epoch of the Mesozoic era in geological time, which began 100 million years ago and ended 66 million years ago, after 79 million years. It is the longest phase of the Phanerozoic.

During the Cretaceous period, the continents were divided by oceans, and the earth became warm and arid. During the period of the largest dinosaurs, many new species of dinosaurs began to appear, dinosaurs still ruled the land, pterosaurs glided through the sky, and huge marine reptiles ruled the shallow seas. The first snakes, moths, bees, and many new small mammals also appeared.

Angiosperms also appeared during this period.
