Probably the most widely known theory, the asteroid impact theory maintains that a meteorite roughly the size of the Isle of Wight crashed into the Earth’s surface, 65 million years ago. The impact triggered a series of powerful earthquakes and forest fires, as well as a number of continental landslides. Combined with the debris that was, according to Dr Joanna Morgan, “ejected at high velocity into the atmosphere” the planet was plunged into darkness, causing a global winter that killed off many of the living species on Earth.

The super volcano theory argues that the asteroid impact was merely a prelude to a number of volcanic eruptions that occurred in an area in India named the Deccan Traps. Researchers have discovered four separate waves of eruptions that released huge clouds of sulfur dioxide into the air, bringing showers of acid rain in turn. These waves are estimated to have occurred between 67.5 and 65 million years ago.`

A team from Holland and Italy discovered fossilised cold water plankton that dates back 65 million years in an area that had previously been warm see in Tunisia. Dinoflagellates and Benthic Foraminifera plankton were found in the first time-dated fossils that provide clear evidence of climate swings. Matthew Huber of Indiana’s Purdue University said: “The fossils indicate that something suddenly made the water cold enough to support these tiny critters.”

The volcano because when the volcano erupts they don’t have enough time to escape. The strong smoky air that they breathe in. Or when they have showers of acid it easy for the acid to target them directly.
I think that the volcano might have have killed the dinosaurs because it’s the dinosaurs could have been hanging around the mountains. Also having the lava killing them.
This is Tai and my DLO on What Killed All The Dinosaurs. We had to read a text that Mrs Kirkpatrick shared with us. Then we got a task to share and write comments underneath.
