10 Facts About Dinosaur Extinction

<p style=”text-align: justify;”>Facts about dinosaur Extinction talk about the mass extinction of the animal and plant species on earth. people conjointly call this event as K-Pg or Cretaceous–Paleogene extinction event. Others like to call it as K-T or the Cretaceous–Tertiary extinction event. This event happened around 66 million years ago and affected the life of all non-avian dinosaurs. Here are different interesting facts about dinosaur extinction:

Interesting Facts About Dinosaur Extinction:-

  1. The Exceptions:

    The tetrapods with the weight more than 25 kilograms or 55 pounds weren’t survived in the mass extinction event. However the crocodiles and leatherback sea turtles survive the event for they live in the aquatic surroundings.
  2. The Cretaceous Period:

    The dinosaur extinction meaning the end of Cretaceous period. the end of this era starts the start of the Cenozoic era that takes places till this present day.

     

  3. The K–Pg Boundary:

    The K–Pg boundary is a term used to call a thin layer of sediment which might found on the terrestrial and marine rocks. Since this boundary is critical as a geological record of the K-Pg event.

  4. The Metal Iridium:

     The metal iridium is plentiful in the boundary clays of K-Pg. The high level of material is extremely high in asteroids, however this material is extremely rare on Earth’s crust.

  5. Luis Alvarez:

    Luis Alvarez was the leader of a team of scientists who proposed the first version of K-Pg in 1980. This event defined because the mass extinction due to the large asteroid or comet which hit the earth 66 million years ago.

  6. The Effect Of K-Pg:

    Due to the large asteroid or comet that hit the earth, it was not possible for the planktons and plants to conduct photosynthesis.

  7. The Alvarez Hypothesis:

    The Alvarez hypothesis is used to call the impact hypothesis. The K–Pg boundary clay featured the rubbish from asteroid after the discovery of Chicxulub crater in the starting of 1990s. The crater is located in Gulf of Mexico that has the dimension at 112 miles or 180 kilometer.

  8. Other Causes:

    Even though some specialists believe in K-Pg, others propose completely different causes of dinosaur extinction like the climate change, volcanic eruption, and changes on the sea level.

  9. The Notable Victims Of K-Pg Extinction:

    There were several different victims caused by the events like the certain plants, insects, lizards, birds, mammals, fish, large marine lizards and pterosaurs.

Dinosaurs roamed the earth for 160 million years till their sudden death some 65.5 million years ago, in an event now called the Cretaceous-Tertiary, or K-T, extinction event. “K” is that the abbreviation for Cretaceous, which related to the German word “Kreidezeit”. Besides dinosaurs, several other species of mammals, amphibians and plants died out at the same time.
