The Silurian (/sɪˈljʊəriən, saɪ-/ sih-LURE-ee-ən, sy-) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at 443.8 million years ago (Mya), to the beginning of the Devonian Period, 419.2 Mya.
Fluctuations in sea level, between 30 and 50 metres (about 100 and 165 feet) in magnitude, continued to occur on a global basis throughout the Silurian time period.During the Silurian Period, the atmosphere came to contain the optimum concentration of oxygen for creating ozone. The maximum ozone production in the upper atmosphere occurs when the oxygen content is approximately 10% of today's level.
Silurian atmospheric carbon dioxide, again although higher than modern values, was

Large expanses of several continents became flooded with shallow seas, and mound-type coral reefs were very common. Fishes were widespread. Vascular plants began to colonize coastal lowlands during the Silurian Period, whereas continental interiors remained essentially barren of life.
The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out.
A significant evolutionary milestone during the Silurian was the diversification of jawed fish and bony fish.

Mythology :
Matsya Avatar of Sri Vigreat
Manu, the first man, caught a little fish that grew to giant size. When the flood approached, Manu saved himself by tying his boat to the horn on the fish's head.
Vishnu knew about Shiva's plan to cause massive floods. Therefore, he incarnated in the form of Matsya (a fish). Moreover, he had to save Manu and his wife Shatarupa, the couple that would be instrumental in conceiving humans once again.
Along with Brahma, the creator and Shiva, the
destroyer, Lord Vishnu is one of the three main male deities in Hinduism and they are together known as the TRIMURTI. Being a part of the Trinity, He has taken ten incarnations and the ten Avatars of Lord Vishnu or the Dashavatara are the several forms He took whenever the universe was in turmoil. Each of Vishnu’s Avatars had the same purpose which they achieved by different means. This divine purpose was the restoration of Dharma or righteousness and to save the planet and the good people from the hands of evils, demons or Asuras.
Matsya (Fish in Sanskrit) was the first Avatar of Vishnu in Hinduism. The great flood finds mention in Hindu mythology texts like the Satapatha Brahmana , where in the Matsya Avatar takes place to save the pious and the first man, Manu and advices him to build a giant boat. Lord Matsya is generally represented as a four-armed figure with the upper torso of a man and the lower of a fish.
It is said that, during the Satya Yuga, the people on earth had become irreligious and disorderly in the way they lived their lives. This is when the Gods collectively decided to flood the earth and prepare it for the process of renovation. Lord Brahma, the creator, had been given the guidelines to remodel the earth by Lord Vishnu. These guidelines were the Vedas, the four principle books of Hinduism. Lord Brahma decided to rest before this grand task as he was quite tired from the process of creation.At this time, a horse-headed demon named Hayagriva ( not t be confused with Lord Hayagriva, the avatar of Vishnu who is considered as a symbol of wisdom and knowledge) came out of Brahma’s nose and stole the Vedas from him. Then Hayagriva went and hid himself deep in the oceans of the earth. Meanwhile, a pious king named Satyavrata who was a great

admirer of Lord Vishnu, regularly worshipped Lord Vishnu and wished to meet Him. So Lord Vishnu decided to pay a visit to Manu.
The story, according to the Matsya Purana, goes like this :
Satyavrata, the king of pre-ancient Dravida and a devotee of Vishnu, who later was known as Manu was washing his hands in a river when a little fish swam into his hands and pleaded with him to save its life. He put it in a jar, which it soon outgrew. He then moved it to a tank, a river and then finally the ocean but to no avail. The fish then revealed himself to be Vishnu and told him that a deluge would occur within seven days that would destroy all life. The fish told Manu that at the end of Kali yug, the mare who lived at the bottom of the ocean would open her mouth to release a poisonous fire. This very fire will burn the whole universe, Gods, constellations and everything. The seven clouds of doomsday would then flood the earth until everything was a single ocean. Therefore, the fish instructed Satyavrata to build an ark to take “all medicinal herbs, all the varieties of seeds, and accompanied by the seven saints” along with the serpent Vasuki and other animals. As the time of the flood approached, Manu’s ark was complete. As the flood swept over the land, Manu asked Vishnu why mankind had to meet such a deadly fate to which Matsya Vishnu told Manu that he was the only moral man alive and that he would be the father of the future generations of men. Matsya killed Hayagriva and returned the Vedas to Brahma. Then he tied himself to Manu’s ark using Vasuki as a rope and protected them from the storm and the floods. When the storms ended and the water subsided, Matsya Vishnu left Manu and the others at the Himalayas, where they could begin human civilization again.
The cause of Sri Vishnu, taking incarnation as a big strong fish, as there will be huge water mass, compared to land mass, is only purposed to save Manu & his wife, for regenaration of human being on Earth. It was an attempt to save the life cycle already been started on this planet. Also, it is saud Lord Vishnu appeared in the form of a fish to save the four Vedas from the submersion and also to save Manu from the Jal Pralay.
From the chronological determinations of geological ages of Earth, showed us, the huge expansion of sea, all over the planet. Land mass, along the shores were also under the water. This is the period, when 80% of the earth's pre-Silurian life forms got extinct. It was the first major geological changes on Earth which triggered plate movements, new dustribution of land & sea, and so the generations of living creatures. And this was the time when first fishes appeared with strong bony structures and a solid horn on its head. As the atmosphere was oxygen optimum and carbon dioxide rich compared today, the life cycle of all the living creatures were different than today. Adaptation must have helped them, s

The appearence of stronger fish with bones in Silurian is compatible at par with the incarnation of Sri Vishnu as a fish. But, saving the most pious and pure human Manu is not at all compatible.

The Matsya Purana mentions many Amarkantaka temples, located near the source of the Narmada river in eastern Madhya Pradesh.
As human or Homosapiens came much much later, in the course of evolution on Earth.The story of Manu and Noah in Old testament of Bible are more or less same. While the birth of Christianity is only 2000 year's old. So, the copyright although remains intact, but the story of Manu and saving him by Matsa Avatar in the Silurian Period can not be true. Forget about human, even reptiles have not reached to Earth during that period.
As per Hindu scripture, Satya (Krita) Yuga started during 3891102 BCE+ 2023 CE= 38,93,125 lakh year before today. While, anatomically modern humans appeared around 3lakh years ago in Africa. Of that, 70,000 years ago, they gradually supplanted the "archaic" human varieties. Non-modern varieties of Homo are certain to have survived until after 30,000 years ago, and perhaps until as recently as 12,000 years ago. According to recent genetic studies, modern humans may have bred with two or more groups of archaic humans, including Neanderthals and Denisovans.
Archiac human
Neanderthals
Even if, we consider, Manu was an archiac man, then also his relation with Lord Vishnu's incarnation to Matsya can not be linked through the proven time scale!
It is indeed a good concern and deep thought provoking subject for us, specially Hindus, to find out the presence of Avatars of Lord Vishnu and mortal human civilisation. Our submission of Four Yugas and its cyclic nature might be correalatable with Earth's constant destruction & new making through eternal times. But where we do stand in this huge time span with all our Gods or at least with our Tridevas ; Brahma- Vishnu - Mahesh, we are yet to find out. I am searching everyday, from all the available sources but yet to find conclusively.
Only then, the thought processes inclined towards the unknown and unexplained signatures left on Earth, by a species, intelligent than us, stronger than us, provocate for accepting the theory of "Are Gods are human from other planet or entity"?
