What happend in the period between dianosur extinction and the appearance of the first humans?
Scientists theorize an ice age or other global event the dinosaurs couldn't adapt to, which wiped them out.
The last mass extinction of dinosaurs on Earth occurred between which two geologic periods?
asteroid attack
What is the difference between extinction and species endangerment?
Extinction refers to complete eradication of a species such as the Warrah or Dinosaurs (things that no longer exist), whereas an endangered species is merely under threat of eventual extinction, but is not there yet, like a panda or a California Condor.
3 possible contribution of extinction of the dinosaurs between the creatceous and tertiary?
Impact event: The most widely accepted theory is that a large asteroid impact caused drastic environmental changes leading to the extinction of the dinosaurs. Climate change: Volcanic activity and changes in atmospheric composition could have led to significant climate disruption, affecting the food chain and ultimately leading to the extinction of the dinosaurs. Competition and evolution: The rise of new species, particularly mammals, may have outcompeted dinosaurs for resources, leading to their decline and eventual extinction in the Cretaceous-Tertiary boundary.
Did the first sharks appear after the dinosaurs?
Sharks appeared long before the dinosaurs. Their oldest fossils date back to somewhere between 450 and 420 million years ago, before there were land animals and when few plants had even colonized land. The first dinosaurs didn't appear until 230 million years ago. The sharks also outlasted the non-avian dinosaurs during the K-T extinction 65.5 million years ago, and they will probably continue to swim in the oceans for hundreds of millions of years to come.
How many years did the dinisors livE AGO?
Dinosaurs lived between approximately 230 million and 65 million years ago, during the Mesozoic Era, which is divided into the Triassic, Jurassic, and Cretaceous periods. The last dinosaurs disappeared around 65 million years ago, likely due to a mass extinction event. This means that dinosaurs roamed the Earth for about 165 million years before their extinction.
Why don't dinosaurs existed?
They did exist, between around 225-65 million years ago, and were wiped out by the last Mass Extinction Event (summised to be a comet impact).
Were mastodons alive with the dinosaurs?
No, Mastodons were alive from the late Miocene/early Pliocene until around the end of the Pleistocene, 10,500 years ago give or take. There is nearly 60 million years of time between the extinction of the dinosaurs and the rise of the Mastodon.
What is the link between meteors and dinosaurs?
the link is that it is a theory that a huge meteor or comet wiped out the majority of the dinosaurs when it impacted on the earth's surface and caused a huge amount of dust to rise into the air and blocked out the sun which meant that the dinosaurs could not breathe and probably froze to death and the impact would have caused an explosion that would be an equivalent to thousands of atomic bombs going off at once I am not totally sure of the facts but this is a start for you...also I think this is a theory and may not have happened at all unless we have testamony from someone who was around back then...sorry about the pun
What is the k-t mass extinction and when did it occur?
It occurred between the Cretaceous period at the end of the Mesozoic era and the Tertiary period at the beginning of the Cenozoic era. It's mostly known for wiping out the dinosaurs. Any species that weighed over 100 kg vanished (60-80% of all species).
Did the impact of a large meteorite cause the extinction of the dinosaurs?
Well, it was an awful long time between the extinction of the dinosaours (about 65 million years ago) until "we" showed up - about 50 thousand years ago. So I think you'd be safe to say their extinction didn't have any effect on us, per se.. However, whatever caused their extinction did lead to the emergence of other types of animals on the planet, mammals being one of them, who may not have prospered so well had they all been eaten by dinosaurs. Despite what some people might think, 'mankind' and 'dinosaurs' never walked the earth together. Except for crocodiles, and perhaps, sharks - they've been around A Long Time, and may be the only surviving link to the age of Reptiles.
When triceratops was on earth what was the period time?
Triceratops existed between 68 and 65.5 million years ago. That was at the very end of the Cretaceous time period. The Cretaceous period was the last period of the Mesozoic, or Age of Dinosaurs. This means that Triceratops were one of the very last dinosaurs to exist, and were wiped out by the K-T extinction event that wiped out all of the world's dinosaurs.
