Dinosaurs Extinct facts
While investigating facts about Dinosaurs Extinction and Dinosaurs Extinction Date, I found out little known, but curios details like:
If the history of the universe was condensed into a year, the Milky Way would form on May 15, life on earth would appear on September 21, and the dinosaurs would go extinct on December 30. Modern humans would evolve on December 31 at 11:52 PM and Columbus would discover America at 11:59:58 PM.
how dinosaurs extinct from earth?
If the asteroid that killed the dinosaurs arrived just 30 seconds later, it would have landed in deep ocean water which would have absorbed much of the force of the impact. The resulting extinction would have been less severe, many dinosaur species would have survived, and humans would not exist
What caused the extinction of dinosaurs?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what caused dinosaurs to go extinct. Here are 50 of the best facts about Dinosaurs Extinction Event and Dinosaurs Extinction Cause I managed to collect.
what made dinosaurs extinct?
-
There were four mass extinction events before the one that killed the Dinosaurs. The most severe killed a staggering 97% of all species. All life on Earth today is descended from the 3% that survived.
-
The hoatzin is the last surviving species of a line of birds that diverged from all other birds 64 million years ago, just after the dinosaur extinction event, and that hoatzin chicks have claws on their wings
-
I learned that if the entire history of Earth is displayed with one year in a calendar dinosaurs would get extinct on December 25th and the first homo sapiens would appear around 11:36 pm on December 31th.
-
Under modern scientific classification Dinosaurs are not considered extinct, and instead live among us as birds.
-
The coelacanth, a fish thought to have disappeared with the dinosaurs until an amateur fisherman caught one in 1938, more than 66 million years after their supposed extinction
-
The dinosaur extinction event is marked by a thin layer of sediment all over the world, which contains 160 times as much Iridium as normal - evidence of the global devastation caused by an asteroid impact
-
There were 5 mass extinction events on earth, with the extinction of dinosaurs not even being the largest.
-
Sudbury, Ontario is located within the second largest known crater on Earth, formed by an impact larger than the asteroid that made the dinosaurs go extinct
-
Archaebacteria are considered to be one of the earth's oldest forms of life. They survived the extinction events that killed off the dinosaurs.
-
There are actually several craters dated to the extinction of the dinosaurs. In addition to 180 km Chicxulub crater, there is the 24 km Boltysh crater, the 20 km Silverpit crater, and the controversial and much larger 600 km Shiva crater, suggesting a multi-impact disaster.
Reason why dinosaurs extinct?
You can easily fact check dinosaurs extinct reason by examining the linked well-known sources.
If Earth’s history was represented by 24 hours, the dinosaurs would have become extinct at 11:41pm and human history would have begun at 11:54:43pm.
Although most dinosaurs are extinct, they are not fully extinct because birds are considered dinosaurs.
That, besides the extinction event that wiped out the dinosaurs, there has been 4 other Mass Extinction events to occur millions of years apart that would nearly wipe out all life on earth. - source
The Shiva crater, a proposed asteroid impact site off the west coast of India over 500km across that if confirmed, would be the largest known impact site on earth, and a possible cause for the extinction of the dinosaurs and unusual northward drift of India
Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs. Also, all but 2 species of penguins mate in groups of thousands, that's right, penguins are orgy animals. - source
When did dinosaurs go extinct?
That the dinosaur asteroid extinction hypothesis was only proposed in 1980
How dinosaurs extinct video?
The beginning of the Cenozoic Era began when the Mesozoic Era ended and dinosaurs became extinct.
One of the first dinosaur bones discovered was interpreted as belonging to an extinct race of giant humans and was named 'Scrotus Humanum' for its resemblance to a human scrotus. Scientists later campaigned to have this title scratched from the record.
The asteroid impact responsible for the extinction of the dinosaurs created a megatsunami estimated to have been more than 100 m (330 ft) tall. Had the asteroid struck the deep sea (instead of a relatively shallow sea) the wave would have been 4.6 kilometres (2.9 mi) tall.
Dinosaurs were in steep decline before the K-T Meteor, with the last species representing only 14% of all species ever to have existed, and net speciation at -.2/Myears (A species going extinct every 5 million years)
During the Cretaceous there existed a group of bird-like animals called the Enantiornithes. These animals looked like birds but had reverse shoulder anatomy and became extinct with the asteroid that killed the dinosaurs.
