New research indicates that the underground environment created by the asteroid that caused the extinction of the dinosaurs lasted for 8 million years, much longer than the previously thought 2 million years. This environment was characterized by a buried hydrothermal system of porous rock, hot water, and chemical nutrients, which supported new life.
The asteroid that caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected. While previous research showed the buried hydrothermal system of porous rock, hot water, and chemical nutrients may have lasted 2 million years, new research says it lasted for 8 million years.
