Dinosaurs developed\u00a0into a very vast group of animals with a diverse\u00a0array of physical features, including modern birds.<\/p>\n<p>Contrary to what many we\u00a0think, not all dinosaurs lived during the same geological era.\u00a0For example, Stegosaurus, lived during the Late Jurassic Period, about 150 million years ago.\u00a0Tyrannosaurus rex\u00a0existed\u00a0during the Late Cretaceous Period, about 72 million years ago.\u00a0Stegosaurus\u00a0was extinct for 66 million years before\u00a0Tyrannosaurus\u00a0appeared on Earth.<\/p>\n<p>In\u00a0the Mesozoic Era (an era\u00a0of more than 180 million years which includes\u00a0Triassic, Jurassic, and Cretaceous periods), a \u00a0non-avian dinosaur developed\u00a0into a species of avian dinosaur. This avian dinosaur is the considered as the first bird and the ancestor\u00a0of all birds. All the\u00a0non-avian dinosaur went extinct 66 million years ago.<\/p>\n<p>There are many\u00a0theories as to what might\u00a0have contributed to the mass extinction of non-avian dinosaurs and other species at the end of the Cretaceous Period. It is for sure\u00a0that a massive asteroid or comet struck Earth during this period, causing a dramatic shift in Earth\u2019s climate. Some scientists anticipate that this impact had catastrophic consequences for life on Earth. But other factors, including changing sea levels and large-scale volcanic activity, may also have played an\u00a0important\u00a0role in this mass extinction.<\/p>\n<p style=\"text-align: center\"><strong><a href=\"https:\/\/entri.sng.link\/Bcofz\/yv45\/8wer\" target=\"_blank\" rel=\"noopener\">Attempt free GK Mock Test!

The sharp points cut\u00a0the meat, and the serrations helped slice it by catching and tearing muscle fibers. Meat eaters didn\u2019t cut\u00a0or grind their food; they swallowed whole chunks.<\/p>\n<p>Herbivorous dinosaurs had teeth of various shapes designed for their particular diets.\u00a0For example, Triceratops, had 100s\u00a0of teeth that formed a solid \u201cwall\u201d with sharp ridges. The teeth helped them\u00a0to chop off vegetation. Other plant eaters, such as\u00a0Anatotitan, possessed wide flat teeth that\u00a0helped them\u00a0to grind up tough vegetation. The long-necked dinosaurs, like\u00a0Diplodocus, had long pencil-like teeth that helped \u00a0to rake the leaves off branches. These dinosaurs swallowed\u00a0whole leaves. They also consumed\u00a0small stones, called gastroliths, \u00a0to grind up the food in their stomachs, much the same way that modern birds, such as parakeets and chickens, do now a days.<\/p>\n<p>From an individual footprint, scientists can guess\u00a0the height of the dinosaur that made it. A rough estimate guess of leg length is acquired\u00a0by multiplying the print length by four.<\/p>\n<p>A footprint can also give us hints\u00a0about the kind of dinosaur that made it. A 3 toed, sharp-clawed print means that it is\u00a0likely to be the footprint of a theropod\u2014usually a carnivore. A three-toed print with rounded toes mostly probably belonged to an ornithopod dinosaur\u2014a\u00a0plant eater.

At present, two main ideas are battling it out within the scientific community: Were dinosaurs victims of heavenly body violence, or more Earthly woes?<\/p>\n<p style=\"text-align: center\"><strong><a href=\"https:\/\/entri.sng.link\/Bcofz\/yv45\/8wer\" target=\"_blank\" rel=\"noopener\">Attempt free GK Mock Test!

In 1980, they proposed the notion that a\u00a0meteor the size of a mountain crashed into Earth\u00a066 million years ago, filling the earth with gas, dust, and debris that forcefully altered the climate.<\/p>\n<p>The main \u00a0piece of evidence provided by the duo is an oddly high amount of the metal\u00a0iridium\u00a0in what\u2019s known as the Cretaceous-Paleogene ( K-Pg), layer\u2014the geologic zone that seems to cover any known rock layers incorporating dinosaur fossils. Iridium is comparatively rare in Earth&#8217;s crust but is abundant in stony meteorites, which led the father and son to conclude that the mass extinction was caused by an extraterrestrial object. The theory gained even more acceptance when scientists were able to connect the extinction event to a large impact crater along the shore of Mexico\u2019s Yucat\u00e1n Peninsula. At about 93 miles wide, the\u00a0Chicxulub crater\u00a0appears to be the correct size and age to account for the dino die-off.<\/p>\n<p>In 2016,\u00a0scientists drilled a rock core inside the underwater part of Chicxulub, discovering a sample stretching deep beneath the seabed. This rare peek inside the guts of the crater proved that the impact would have been strong enough to send deadly amounts of vaporized rock and gases into the environment, and that the effects would have remained for years. And in 2019, paleontologists digging in North Dakota discovered a\u00a0treasure trove of fossils extremely similar \u00a0to the K-Pg boundary, essentially capturing the remains of an entire ecosystem that were present shortly before the mass extinction. Tellingly, the fossil-bearing layers contain loads of small glass bits called tektites\u2014likely blobs of melted rock emerged by the impact that solidified in the environment and then rained down on the Earth.<\/p>\n<h3><strong><b>Volcanic fury<\/b><\/strong><\/h3>\n<p>However, other scientists hold back that the evidence for a massive meteor impact event is indeterminate, and that the more likely offender may be Earth itself.<\/p>\n<p>Ancient lava \u00a0in India known as the\u00a0Deccan Traps\u00a0also \u00a0match nicely in time with the end of the Cretaceous, with huge outpourings of lava spewing forth between 60 and 65 million years ago. At present, the resulting volcanic rock covers nearly 2 lakh sq.miles in layers that are in places more than 6 thousand feet thick. Such a huge explosive event would have choked the skies with carbon dioxide and other gases that would have hugely impacted the Earth\u2019s climate.<\/p>\n<p>Proponents of this theory show several clues that suggest volcanism is a better fit. For some studies display that Earth\u2019s temperature was changing even prior to the proposed impact event. Other discoveries has found\u00a0proof for mass die-offs\u00a0much earlier to 66 million years ago, with some signs indicating that\u00a0dinosaurs in particular were already in a slow decline\u00a0in the late Cretaceous. What\u2019s more, volcanic activity is regular on this planet and is a arguable culprit for other ancient extinctions, while giant meteor strikes are not that common. This all makes sense, supporters say,\u00a0if ongoing volcanic eruptions were the main cause of the world-wide K-Pg extinctions.<\/p>\n<p style=\"text-align: center\"><strong><a href=\"https:\/\/entri.sng.link\/Bcofz\/yv45\/8wer\" target=\"_blank\" rel=\"noopener\">Attempt free GK Mock Test!

It\u2019s possible that the dinosaurs were the unlucky recipients of a\u00a0geologic one or two punch, with volcanism weakening ecosystems strong enough to make them undefendable to an incoming meteor.<\/p>\n<p>But that impression depends a lot on more fine dating of the Deccan Traps and the Chicxulub crater. In 2019, two separate studies looked at\u00a0geochemical clues from Deccan Traps lava\u00a0and came to slightly different conclusions, with one paper conveying that the volcanoes played an important role in the dinosaurs\u2019 demise by causing pre-impact declines, and the other saying the eruptions came\u00a0after\u00a0the impact event and may have played only a tiny role in ushering along their end.<\/p>\n<p>This debate may go on for years, as scientists dig up new clues and develop new techniques for understanding the past. But whether space invaders or loads of lava are to blame, it\u2019s distinct that scientists studying the dinosaurs\u2019 last gasp are revealing important lessons about the effects of dramatic climate change on Earth\u2019s dwellers.<\/p>\n<p style=\"text-align: center\"><a href=\"https:\/\/bit.ly\/3MWTnuS\" target=\"_blank\" rel=\"noopener\"><strong>Grab study materials to strengthen your GK !!!

The K-Pg boundary, or the K-T boundary, is a thin layer of deposit found in the geological record. This thin layer consists of high levels of the metal iridium, which is uncommon in the Earth\u2019s crust, but is easily found in asteroids.<\/li>\n<li>The Chicxulub crater located underneath Chixulub, Mexico on the coast of the Yucat\u00e1n Peninsula, is considered to be the impact crater left by the asteroid or comet that led to the extinction of the dinosaurs.<\/li>\n<li>The asteroid or comet was approximated to be between six and nine miles wide.<\/li>\n<li>The Deccan Trap hypothesis is another extinction theory. Some scientists believe that the Deccan Traps flood basalts caused the extinction of the dinosaurs by releasing large amounts of dust, sulfuric aerosols and CO2 into the air. This would have obstructed the sun and hindered photosynthesis, ultimately collapsing the food chain.<\/li>\n<li>The multiple impact hypothesis is one more such extinction theory. Some scientists believe the Earth suffered from multiple impact events at the same time. These multiple impacts would have been same as the impact event that happened to Jupiter in the 1990s with the comet called Shoemaker-Levy 9.<\/li>\n<li>Some other dinosaur extinction theories include disease or sea level change, massive volcanic eruptions, climate change<\/li>\n<li>Finally, the extinction of the dinosaurs cleared the way for the evolution of mammals and humans. If the dinosaurs hadn&#8217;t gone extinct about 66 million years ago man may never have evolved.<\/li>\n<\/ul>\n<p style=\"text-align: center\"><a href=\"https:\/\/bit.ly\/3MWTnuS\" target=\"_blank\" rel=\"noopener\"><strong>Grab study materials to strengthen your GK !!!
