The Permian Extinction caused by the impact of a great asteroid at the antipodal point to the Siberian Traps, the resulting complex crater with two secondary rings, and origins and consequential distinctive native flora and fauna of New Zealand
This blog contains the full content of a book with about 100 pages, illustrated.
It presents a bold theory that was born from the test of a hypothesis:
Could it be proved that, in the same way that an asteroid caused the extinction of the dinosaurs, other asteroids were responsible for the other great extinctions?

The theory currently admited for extinctions says that they were caused by various causes, the most common of which being random episodes of intense volcanism.
The only extinction accepted as caused by the impact of an asteroid was that of the Cretaceous, 66 million years ago.
To prove this hypothesis, it would be necessary a study capable of associating each extinction event with an impact occurrence and eventually, an event of intense volcanic activity.
But impact craters on our planet are difficult to locate:
Even the most famous of these, Chicxulub, is hardly identifiable in satellite images and it was only found by seismic surveys by oil companies.
There are a number of explanations for this apparent lack of evidence...
Our planet quickly destroys evidence due to erosion and tectonics, major impacts only occurred in the remote past when the Earth had not yet cleared its orbit from the remnants of the formation of the solar system, the largest crater on Earth has a diameter of 330 km and it is two billion years old, etc., etc., etc.
But perhaps the biggest cause is that no one even imagines that there may be other craters larger than Chicxulub — it's an extremely out of the box thought.
No one imagines that a crater like this could even exist:
* This scheme is only intended to facilitate the visualization of the circularity of the crater showing the Transantartic Mountains; a scheme closer to the possible reality is shown in the section Wegener Crater: Primary cause of the Permian Extinction.
Nowadays the crater is fragmented in 4 main parts:
Few in the scientific community propose to study this specific subject, after all, the topic does not generate knowledge applicable to the mining industry, which is what our society expects from professional geologists.
Much less in the area of Paleontology, which has always been my interest and for which I gave up because I could not see any job opportunities in my country.
One of the advantages of being able to research without being linked to the academic environment, but knowing its rigors, is the freedom to research without compromises — the result is more time consuming, but it is pleasurable like any reward from a true liking of the matter.
And it was by testing this hypothesis of impact events capable of causing extinctions that I was able to find evidences not considered by Science until now.
Craters so large that they were not recognized as craters because they are much larger than what Science expects to find — Chicxulub in Mexico, with 180 km, is considered a large crater, and Vredefort in South Africa, with its 300 km, is considered a gigantic one.
Both are small ones in view of the results found in this research.
The reasoning and scientific method employed by us allowed us to perceive a reality quite different from that accepted by the academic community.
And so, despite the surprising results achieved, I was unable to present them to this community — in fact, I was not even able to be received or answered via phone or email at various universities.
But to be accepted and validated, my theory would need to be peer reviewed by members of the scientific community.
How can I get this review if no one is willing to even read my study?
How can I get this review if no one is willing to even reply to my emails asking them to read my study?
Life is short and I have no more time to waste knocking on doors of those who refuse to open them.
For this reason, I have decided to make the final part of my research — the most surprising and the one I arrived at after years of reasoning and research, but also the one with the most glaring evidence — freely available to readers around the world.
Let those people genuinely interested in this matter judge it based on these evidences presented — you will say if what I have to say deserves credit.
Only after the relevance of this work is recognized I will be able to present other solid evidences, albeit more subtle ones, that associate — if not all of them, at least most of the large and medium extinctions — to the occurrence of asteroid impacts on our planet.
May you reader enjoy the same pleasure that I had when putting the pieces of this planetary-sized puzzle together, pieces that were discovered and elaborated by geologists, peleontologists and researchers from all over the world — a picture which I have had the joy of seeing for the first time.
Cheers, have fun with this presentation and I hope this presentation may let you see the world with new eyes,

The small size difference is due to the cropping of the image.

Are you familiar with the studies of the "Holocene Impact Working Group"? This group studies the plentiful evidence around the globe for major impacts of the last 10k years, including Megatsunamis. You can look them up.
