there has been a time in my existence whilst i'll reliably spell the notice "paleontologist" and never my final identify.
So this can be anything that is intended much to me. So the last thing i'll do-- I acknowledged 3 issues.
I'm going to speak to you approximately paintings in Utah. i will consult you approximately why we must always care approximately dinosaurs.
And on the finish, i'll make a plea to all of you in line with a few paintings that i have been doing lately approximately children and nature.
So permit me get issues began. once we take into consideration time, we predict approximately time in scales which are very, very tiny-- a yr, couple of years possibly, perhaps 10 years, on the such a lot a hundred years.
100 years turns out demanding to think. Paleontologists day-by-day need to imagine in time scales which are some distance past this.
So i need to stroll you again in time to examine Planet Earth and watch it switch in opposite.
So it truly is like displaying a film, yet in opposite. So this can be the way in which the Earth appears at the present time.
And after all, we will be able to all realize right here. there is North the US and South the USA and Africa and Europe and Asia and Australia.
So we are someplace up the following. Now, if we return in time purely 50,000 years-- and also you may perhaps say, 50,000, that is much.
But for a paleontologist, that is the day before today. 50,000 years, issues glance the exact same when it comes to how the Earth's continents are in comparison to one another.
But you will find all this white stuff. that's the Ice Age, 50,000 years in the past. And if we return, today's, Ice Age, latest, ice age.
And there has been sufficient ice in Seattle to bury the distance Needle simply. extraordinary.
Think approximately that we might be below a mile of ice thereabouts. I suggest, totally extraordinary.
So let's step again additional in time. 50,000 years, like I acknowledged, that is type of the day prior to this for a paleontologist.
Let's get greater than 10 occasions, over a hundred instances again, fifty five million years in the past. And you can now see, issues are commencing to swap on this planet.
South the United States and Africa are nearer jointly. North the USA and Europe are nearer jointly than they have been.
Let's proceed. So this is often nonetheless, dinosaurs lengthy extinct, fifty five million years in the past. The final dinosaurs are approximately sixty six million, with one exception we will speak about later.
Now, we return to ninety million. So we have now virtually doubled that point. And ninety million years in the past, you will see that that South the United States and Asia are actually becoming jointly like items in a puzzle.
North the United States is underwater in its heart. And i'm going to speak a section extra approximately that during a minute.
And Europe is a sequence of archipelagos. And the opposite factor you are going to discover is that there is no polar ice caps.
There are none. So this day, we all know we are living in a global that is warming up. humans name it international warming.
And but, we're nonetheless in an Ice Age. We nonetheless have polar ice caps. yet we're heading to an international that's extra like this.
