Paleontologists around the world pay attention to discoveries made in Tanis, North Dakota, United States. This paleontological area contains fossils that may contain evidence of earth’s influence. asteroid The event that caused the extinction of the dinosaurs.
One in particular is a well-preserved leg with dismembered skin and bones from a thescelosaurus that may have died the day the celestial body fell. The discovery, if proven, will be the first major evidence of extinction.
We know from the fossil evidence found today that dinosaurs lived thousands of years ago. With dating techniques, it is possible to predict when animals lived on the planet.
But there was one question that worried the researchers: They realized that the animals went extinct in a relatively short period of time. It was later hypothesized that the fall of a large meteorite in what is now Mexico’s Yucatan Peninsula would be responsible for putting an end to the dinosaurs.
The Chicxulub effect, as is well known, is a theory with little evidence to date. After all, where are the remains of animals that died as a result of the impact? But that may be about to change with the fossils found at Tanis.
Three thousand kilometers from the area of influence, the paleontological site is chaotic, littered with animal and plant remains that appear to have been carried by the waves and spilled into the side of a prehistoric river running through the area.
However, with painstaking work, experts are able to separate and identify each petrified fragment. For example, traces of non-native sediment-bearing sturgeon and twigs were found on the gills: these may have been hurled into the sky by impact from miles away.
The finds also include a fossil of a turtle stuck on a stake, mammal remains, horned Triceratops skin, a pterosaur embryo in an egg, and even possible fragments of the asteroid.
The BBC team, which has been following the excavations in the region for three years, produced the documentary “Dinosaurs: Last Day with Sir David Attenborough”, which will be broadcast on British TV on 15 April.
