Dinosaurs were probably made extinct by a combination of colossal volcanic eruptions and meteorite strikes, according to studies from Princeton University.
The studies reject the prevailing theory that a single large meteorite caused the dinosaurs’ extinction.
The researchers found a trail of dead plankton that links the mass extinction to large-scale eruptions of a primeval volcanic range in western India. They also found traces of a meteorite nearby.
The study is published this month in the Journal of the Geological Society of India.Read more at Princeton University
