Don't let it happen to us like the Dinosaurs.

We have heard Elon Musk declare that for humanity to survive an extinction, a catastrophe we should colonize Mars, many will say that he is a bit obsessed with Mars but deep down he is a bit right, we should be an interplanetary species and I think that one day we will be not as fast as Elon Musk wants, but little by little we will be. If we succeed we will avoid problems like what happened to the dinosaurs, we will also avoid it if we improve our planetary defense and manage to prevent an asteroid or a comet from destroying our planet, that happened to the dinosaurs that became extinct due to the impact of a asteroid of about 10 kilometers that hit Chicxulub, what is now the Yucatan Peninsula.

This site in Tanis is known as the cemetery of the dinosaurs and it is believed that all the fossils that have been found there died in the same event at the same time, in the impact of the asteroid about 66 million years ago because Remains of the chemical elements that went with the asteroid have been found and that could be analyzed within the materials that have been found together with the fossils. In this extinction non-avian dinosaurs died, although the avian ones, from which birds defend and had evolved ships and at that time there were already some birds that had characteristics like modern birds and birds, at that time there was a canal little deep similar to what we now know as the red sea that crossed the center of north america and connected Tanis this region of north dakota with the caribbean, it is believed that the impact caused catastrophic flooding and flooding but beware it was not necessarily a giant wave that came from the Caribbean up to 3000 kilometers to the north.

Researchers believe that the powerful impact of the asteroid originated a seiche, this seiche originated in all the lakes and rivers on the planet, a seiche is a standing wave that affects an enclosed or partially enclosed body of water, the seiche are the related phenomena with earthquakes that affect lakes, reservoirs or very boxed rivers.

An example of this phenomenon was shown in the Tohoku earthquake in Japan in 2011, the seismic shocks caused large waves very far from the epicenter even in the lakes of Norway 8,000 kilometers away, a place where it would have been impossible for the Earth to physically reach. wave of a tidal wave in Japan, in addition the waves of the seiche of norway arrived in only 30 minutes from the beginning of the earthquake in Japan.

This earthquake in Japan has served as a reference for how the impact of the Chicxulub asteroid could cause catastrophic waves, terrible waves in rivers and lakes around the world and affect this area of ​​Tanis, killing the animals that there, among the victims found in the fossils of Tanis there are numerous fish there is the fossil of a turtle inserted in a fossilized wooden stake of course and we can also find fossils of small mammals.

We have to bear in mind that many species of mammals, including humans, also became extinct in that event, and all current mammals are the descendants of the handful of species that managed to survive the impact and subsequent climate catastrophe. The victims of Tanis, well, now they are news because it turns out that the BBC has made a documentary that premiered on April 15, a documentary that has involved three years of filming work, and has provided the voice of Sir David Attenborough, an actor who is now 95 years old. and is still active; we are the descendants of all the species that survived the mass extinctions, of that handful of species.
