How many hours were in a dinosaur's day? The dinosaurs were around 100 million years ago, which at the current rate [of day lengthening] adds up to 2000 seconds, which is less than an hour.. But while the lengthening of the day adds up, the spin down rate was probably greater in the past, she adds.

When did dinosaurs become extinct? When did dinosaurs become extinct? Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years. If all of Earth time from the very beginning of the dinosaurs to today were compressed into 365 days (1 calendar year), the dinosaurs appeared January 1 and became extinct the third week of September.

- Dinosaurs first appeared in the Triassic period about 230 million years ago. Non-avian dinosaurs roamed the earth until about 65 million years ago and then were wiped out, … most like by the impact of an asteroid or comet. Birds, which are now classified with the dinosaurs, continue to live to this day. Dinosaurs lived on earth for over 160 million years. They were the dominant terrestrial vertebrates from the late Triassic period (around 230 million years ago) to the end of the Cretaceous period (around 65 million years ago).

- The Bible teaches that God made the heaven and earth, the sea, and all that is in them in the six days of creation. That answers the question as to how long the dinosaurs have been on this earth. They did not appear on this earth 225 million years ago and then die out some 65 million years ago.

About dinosaurs Cretaceous Period (145 – 65 million years ago) During the Cretaceous the land separated further into some of the continents we know today, although in different positions. This meant that dinosaurs evolved independently in different parts of the world, becoming more diverse. Other groups of organisms also diversified.

When did DINOSAURS exist? If man has existed for only a short time period (usually about 6,000 to 10,000 years ago) then how do we explain the long ages that science has assigned to these animals? Did the earliest known dinosaurs begin to appear in the Triassic period some 245 million years ago? When exactly did they live?

ERA OF THE DINOSAURS ERA OF THE DINOSAURS. Dinosaurs roamed the planet for about 165 million years, during a time in the Earth’s history called the Mesozoic Era. It is difficult to imagine how long this was, until we compare it with ourselves: humans have lived on Earth for less than two million years.

How Long Did Dinosaurs Live on Earth? Quick Answer. Dinosaurs lived on Earth for about 175 million years, until they were entirely wiped out by the K-T extinction event at the end of the Cretaceous Period. They lived during the Mesozoic Era, and examples of dinosaurs can be found in all three periods of that era.

- Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic period. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago.

- Yes, there was a pre-dinosaur Period. It was called Mesozoic Era . The Mesozoic is divided into three time periods: the Triassic (245-208 Million Years Ago), the Jurassic (208-146 Million Years Ago), and the Cretaceous (146-65 Million Years Ago).rom 250 million years ago up until 65 million years. There were life forms much earlier but they were not dinosaurs. They were during a timeline called Early life. The creatures were reptiles, bugs, fish, shell fish, and so on.

Are all fossil animals dinosaurs? Paleontologists now have evidence that dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago) the continents we now know were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.

EXTINCTION OF THE DINOSAURS The period between the extinction of the dinosaurs and the present day is called the Age of Mammals or Cenozoic. Mammals appeared on the earth long before the extinction of the dinosaurs; in fact, dinosaurs and mammals originated within 10 million years of each other, in the late Triassic about 200 million years ago.

About Allosaurus Back to Dinosaurs for Kids Back to Time Lived Back to 135 Million Years Ago Back to Allosaurus. Allosaurus lived during the Late Jurassic Period around 140 million years ago. It is one of the largest and most fearsome predators to have ever lived on land. Allosaurus had short arms that ended in ten long, sharp, dagger-like claws, which it could use to tear into the flesh of its victims.

About how long ago did dinosaurs become extinct? Best Answer: I think 40-70 million years ago. It may be called the upper cretaceous period. But remember, not all dinosaurs became extinct. Alligators are still prevalent and haven't evolved much since then. And there is a popular theory that dinosaurs evolved into birds.

Dinosaurs and the Bible According to evolutionists, the dinosaurs “ruled the Earth” for 140 million years, dying out about 65 million years ago. However, scientists do not dig up anything labeled with those ages. They only uncover dead dinosaurs (i.e., their bones), and their bones do not have labels attached telling how old they are. The idea of millions of years of evolution is just the evolutionists’ story about the past. No scientist was there to see the dinosaurs live through this supposed dinosaur age. In fact, there is no proof whatsoever that the world and its fossil layers are millions of years old. No scientist observed dinosaurs die.
