Curtin University researchers in Perth, Australia, who were part of a scientific expedition that retrieved core samples from a crater in the Gulf of Mexico have found evidence that the asteroid that caused the mass extinction of the dinosaurs also triggered a giant tsunami.
The research, published in the prestigious Proceedings of the National Academy of Sciences (PNAS) recently, was carried out by a scientific team that drilled deep beneath the Chicxulub crater, which was created 66 million years ago by the impact of a giant asteroid that was believed to have killed three-quarters of all life on Earth.
Lead Australian researcher John Curtin Distinguished Professor Kliti Grice, from the WA-Organic and Isotope Geochemistry Centre (WA-OIGC) in Curtin’s School of Earth and Planetary Sciences, says the team drilled into the crater in order to retrieve rocks from 500 metres (1,640 feet) to 1300 metres (4,300 feet) below the seafloor, finding evidence of the events of the days after impact.
