NASA found the giant Martian shield volcano that produced one new lava flow at its summit every 1 to 3 million years. Scientists reveal that the last volcanic activity ceased about 50 million years ago when large numbers of our plants, animal species, and dinosaurs went extinct.

According to Phys.org, Arsia Mons is the southernmost members of a trio of broad, gently sloping shield volcanoes collectively known as Tharsis Montes. The Arsia Mons was built up over billions of years, though the scientists are still working on the details of dinosaurs.

The researchers hope that the most recent volcanic activity is thought to have taken place in the caldera, time of dinosaur era where 29 volcanic vents have been identified. Scientists stated it's been difficult to make a precise estimate of when this volcanic field was active.

NASA has reported that the caldera is deep enough to hold the entire volume of water that is measured about 68 miles across. The researchers have examined the volcanic feature of dinosaur era within the caldera required image by the Context Camera on NASA'S Mars Reconnaissance Orbiter.

The team mapped the boundaries of the lava flows from each of the 29 volcanic vents and determined the stratigraphy. NASA scientists also performed a technique called crater counting at least 330 feet in diameter to estimate the ages of dinosaurs.

The new research was also conducted by Richardson and his colleagues at the University of South Florida. They were combined to determine the volcanic, equivalent of a batting line-up for Arsia Mons 29 vents. The research suggested that the youngest flows probably occurred 10 to 90 million years ago that is most likely around 50 million years ago.

However, the modeling estimates' of the volume flux for each lava flow. Though, the better understanding is very important because it helps researchers understand the Red Planet's history and also the extinct of dinosaur's.
