It was one of the many astonishing discoveries at the site of a special rock formation in the Hell Creek Formation in North Dakota, USA, which preserved the remains of a cataclysmic period that ended the age of dinosaurs – the most ancient creatures in the world.
bones unearthed includes fish that inhale can explode over time the attacker, the turtle impaled with a stick and a leg that may have been joined by a dinosaur that saw the asteroid strike.
The story of the discoveries takes place in a new documentary called “Dinosaur Apocalypse”, featuring characters like Sir David Attenborough and paleontologist Robert DePalma and out Wednesday on PBS’s “Nova.”
DePalma, a graduate researcher at the University of Manchester in the UK and an expert in the geosciences department at Florida Atlantic University, began working at Tanis, according to fossil sources, in 2012.
Dust and flat are very different with the occurrence of space at the end of the Cretaceous period. At that time, the American Midwest It was a swampy forest and ocean floor that was lost – known as the West Coast Seaway – ran all the way from the present Gulf of Mexico to Canada.
Tanis is more than 3,200 miles away from Chicxulub where the crater impacted left by a star that crashed off the coast of Mexico, but the first findings of the site convinced DePalma that it provided little evidence. something that led to the end of the age of dinosaurs.
The school is home to thousands of well-preserved fish fossils that DePalma believes were buried alive from the ground when a large body of water appeared from a star attack moving from the inside. sea. Unlike a tsunami, which can take several hours to reach a region after an earthquake at sea, a tidal wave, called a seiche, erupts immediately after a massive star falls into sea.
It is confirmed that the fish died within an hour of the impact of the star, and not by the extreme fires or nuclear winter that followed days and months later. That is why “impact spherules” – small pieces of molten rock thrown from caves into space, where they crystallized into glass-like material – were found in the fish gills. Examination of the fish fossils also reveals the star until the spring.
“Evidence after evidence began to write and change history. It’s a promotion of leaders like Sherlock Holmes research, ”DePalma said.
“It takes a while to tell the story of what happened after the incident and you get a rich investment in research.”
Many of the most recent findings have been reported in data not published in research journals. Michael Benton, a professor of vertebrate paleontology at the University of Bristol who has been a consultant on the study of archival literature, said that while it was “a matter of conference” that the document New research has been under investigation before they appeared on television, and he and many other paleontologists have confirmed that fossil sites represented the “last days” of the dinosaurs.
“Some experts say ‘well, it could be the next day or a month before … but I like the simpler explanation, which is the fact that he wrote the dates stars hit Mexico, “he said in an email.
