A team of Mexican researchers assured that there is geological, mineralogical and stratigraphic evidence that reinforces the hypothesis that the dinosaurs were not extinguished by the fall of a meteorite, but rather the area of the alleged impact preserves remains of a volcanic eruption.
In an article published in the Gondwana Gazette, magazine of the Mexican Association of Petroleum Geologists, a working group of the National Polytechnic Institute (IPN) stated that in the Chicxulub area, in the Yucatan peninsula, an “underwater volcanic event” was recorded that coincides with the end of the age of dinosaurs, at the end of the Cretaceous period.
“The study of the sequence of transitional carbonate rocks of marine origin in the contact zone between the Cretaceous-Paleocene does not yield any geological evidence related to the supposed impact of an extraterrestrial lithological body in the region, including iridium, which leads us to seriously rethink the meteorite myth“, stated the doctor Abelardo Cantu, co-author of the research.
The hypothesis that so far generates the most consensus in the scientific community to explain the fifth mass extinction of the Earth is the impact of a huge rock in Chicxulub, which would have had a power equivalent to 10 billion atomic bombs, like the one in Hiroshima.
But in the area of the supposed impact, according to Cantú, with a geophysical record of 1,200 meters deep The presence of sediments of volcanic origin is observed, such as ash, lava, volcanic glass and bentonite, among others.
The academic attributed the extinction of plant and animal species that occurred in that period, including that of the dinosaurs, to evolutionary causes and biological issues.
