It has been over sixty-six million years when shallow sea witnessed the massive asteroid leading to destruction. The bearing of the ordeal was so high that the mountains and 90-mile wide crater were flung around and debris was all over the place it the form of molten glass and rock.
This overall destruction was at such a huge rate that the fishes had the blobs of glasses in their fins and they were gape mouth swimming in the rain. Apart from this, the land animals were throwing on the land by the waves that buried them
In North Dakota, the scientists found out the fossils that are of the fishes that might have died in the few minutes or within minutes of the disaster. Hence, paleontologists are working upon the scene to find more about the asteroid hit that made everything vanished for the dinosaurs.
A Pennsylvania State University paleoceanographer Timothy Bralower said, “You're going back to the day that the dinosaurs died,", "That's what this is. This is the day the dinosaurs died."
The K-T extinction, K-Pg extinction or Cretaceous Paleogene is the terms that are used for the perished species (three out of four). However, dinosaurs were the most affected species among all. Triceratops and T Rex was followed by other species. The marine and freshwater creatures were also the victims of the ordeal including the microorganisms and plants. There was plankton of over 93% in total including birds, dinosaurs branch, etc.
There were many theories and research done in the past about the disaster which was shows the plausible explanation. The father-son duo, Walter and Luis Alvarez, in 1970 examined the period of Paleogene and Cretaceous by understanding the geologic layer. The iridium was the element used due to its rare nature on earth but excessive on asteroids.
Also, "the first mass death assemblage of large organisms anyone has found" was represented by Hell Creek fossils that are the boundary for K-Pg which is authored by Robert DePalma.
As the Ammonites, the squid-like animals, predatory remains, mosasaurs, the aquatic lizard’s predatory remains, and shark teeth were found. Apart from this, dead trees, insects, mammals, Triceratops were also found with the dinosaur tracks, fossil feathers, prehistoric mammals burrows, etc. Even Amber, the tree gunk that is fossilized is also extracted with glass spheres in it.
