Doomsday dinosaurs are extremely wet

At the end of the dinosaurs, the earth was much wetter than scientists imagined, a new study revealed.

65 million years ago, a giant meteorite hit the coast of the Yucatan Peninsula, Central America, and most scientists believe that this event plays a major role in causing the extinction of 70% of living organisms on Earth, including dinosaurs do not fly.

Geophysicists have now created the most detailed 3-dimensional seismic images of the Chicxulub meteorite that is almost submerged under this sea. Data show that the meteorite fell into the water deeper than previously predicted, and thus released large amounts of water vapor 6.5 times into the atmosphere.

The photos also show that the sediment in this pit is rich in sulfur and that they will interact with water vapor to form sulfate aerosols. These compounds cause deadly effects because they cool the climate and cause acid rain. " Huge amounts of water vapor and a significant increase in sulfate aerosols need to be taken into account in models of extinction, " said study leader Sean Gulick at the University of Texas.

The meteorite fall alone may not be enough to cause a major extinction, but the combination of environmental changes may have fueled this outcome.
