Killer Asteroid strike: Miraculously, these ‘dinosaurs’ escaped mass extinction

[ad_1] Birds are the only dinosaur group that survived the terrible asteroid strike that caused the mass extinction of dinosaurs some 66 million years ago. Scientists have been puzzled for years about why birds, descendants of dinosaurs, survived while most others did not, including the fearsome giants that we know all about, Interesting Engineering reports. Now, two new studies have focused on one possible answer: molting.The importance of molting as survival mechanism after asteroid strikeMolting is when birds shed old feathers and grow new ones. Feathers are made of a protein called keratin, which is the same stuff that makes up human hair and nails. Feathers are important for birds because they help them fly, swim, attract mates, stay warm, and protect their skin from the sun. Feath...

Shocking finding! Ancestors of humans survived asteroid strike that killed dinosaurs

[ad_1] There are various studies which show that an asteroid strike on the Earth caused the mass extinction of dinosaurs. While that was a fact, there was a lot of speculation about whether human ancestors were present during the age of dinosaurs or whetherthey came well after the catastrophic event. A recent study has made a shocking suggestion.According to the study by researchers from University of Bristol in the UK and the University of Fribourg in Switzerland, human ancestors such as dogs, bats, and humans co-existed during the Cretaceous era alongside the dinosaurs. The fossil studies of mammals show that they existed 66 million years ago. The molecular data shows that the mammals are older than the Cretaceous Paleogene (K-PG), which also proves that dinosaurs and placental mammal...

Will an asteroid STRIKE Earth? Indian scientist reveals shocking truth

[ad_1] Asteroids pose a clear and present danger to Earth. There have been many asteroid strikes and space agencies are finding new space rocks all the time. So, will an asteroid strike Earth? Did you know that space debris as small as grains of sand or pebbles in their thousands hit the Earth's atmosphere every day? The atmosphere works as a shield, burning up these space rocks. But this is not the case every time. Sometimes, there are meteors in our night sky which burn up high in the atmosphere, but other times huge asteroids actually manage to strike the Earth. One such catastrophic incident happened around 66 million years ago, which is said to have killed off the entire species of dinosaurs. It is known as the Chicxulub event. The asteroid was 15-km wide and it hit the area know...

This monstrous Asteroid triggered a deadly tsunami on Earth

[ad_1] Deadly asteroid crash that killed off the dinosaurs also caused a cataclysmic tsunami across the globe. Nearly 66 million years ago, when a city-size asteroid crashed into Earth, it not only wiped out the dinosaurs but also triggered a monster tsunami rippling around the planet, reveals a new study. The asteroid was about 8.7 miles (14 kilometres) wide. Its crash created a crater about 62 miles (100 kilometres) across near Mexico's Yucatan peninsula and triggered a mass extinction of 75% of animal and plant life on the planet including Dinosaurs. As per the research published in American Geophysical Union Advance, the asteroid crash created a series of cataclysmic events like global temperatures fluctuation; plumes of aerosol, soot and dust filled air; as well as triggered w...

Gigantic asteroid strike on Earth killed dinosaurs 66 mn years ago – Or did it really?

[ad_1] A recent study has cast doubt upon the popular theory that an asteroid strike killed off dinosaurs. All the technology deployed in tracking and finding out details about asteroid strikes and impact on planets, especially Earth, are wrong? The most popular scientific theory says that 66 million years ago, an asteroid smashed into the Earth and caused the extinction of all dinosaurs. Top technological gadgets have been deployed to sift through the evidence to come to that conclusion. But is it really how things happened? A new study, shockingly, disagrees. According to it, asteroids had nothing to do with the demise of the dinosaur population. And contrary to popular belief, it was volcanic eruptions which contributed to...

Dinosaur-killing asteroid’s kin probably caused mystery crater on Earth

[ad_1] The crater, named “Nadir” after the nearby volcano Nadir Seamount, is of the same age as the Chicxulub impact caused by a huge asteroid. The ocean floor is famously less explored than the surface of Mars. And when our team of scientists recently mapped the seabed, and ancient sediments beneath, we discovered what looks like an asteroid impact crater.Intriguingly, the crater, named “Nadir” after the nearby volcano Nadir Seamount, is of the same age as the Chicxulub impact caused by a huge asteroid at the end of the Cretaceous period, around 66 million years ago, which wiped out the dinosaurs and many other species. The finding, published in Science Advances, raises the question of whether the crater might be related to...
