Shocking Ice Age Discovery Has Been Made in the USA

Bright Side

🤿 Divers went down into a dark Florida sinkhole and found something nobody expected. Buried inside were fossils so old they predate modern humans by hundreds of thousands of years. We’re talking about a time when giant animals ruled North America. This video breaks down what they found, how it survived underwater, and why scientists are freaking out. Don’t miss this video if you love discoveries that completely rewrite prehistory.

00:00divers have found something incredible in a Florida sinkhole and it was stop we

00:07need to leave a warning here you're about to hear some pretty unusual

00:10scientific information this knowledge will make you the smarty pants in your

00:15friend group but there's also a risk that they'll look at you as a nerd so

00:20perhaps it would be better for you to keep this knowledge a secret in any case

00:24it won't be superfluous so you know that scientists divide the history of our

00:31planet not only by time periods but also by which animals lived at a certain time

00:37for example 2,000 years ago Earth was inhabited by the blobfish and

00:43scientists call this time the blobfish period it's a joke there's never been

00:48such a period but you get the gist the period between about 419.2

00:54million and 358.9 million years ago is called the devonian period or the age

01:01of fish do you know why because the first fish began to appear on the planet the

01:09paleogene is the period of large mammals the famous Jurassic period marks the

01:14appearance of giant dinosaurs which we often see in the movies even now we live

01:20in a certain period called the quaternary period it began about 2.6 million years

01:26ago and continues to this day this is the time of humans and modern animals so the

01:33next time somebody asks you what time it is you can just answer it's the

01:37quaternary period in short the names of these periods depend more on what

01:43creatures inhabit the planet the longest period is the Precambrian period or age

01:49of early life the time when life on the planet started to form soft-bodied

01:54worms and jellyfish swam in the ocean while microorganisms lived on land this

02:00period occupies almost 90 percent of the Earth's total geological time it started

02:08about 4.5 billion years ago and ended 540 million years ago oh it's still a video

02:16about divers don't forget we'll get back to them soon considering all these periods do

02:22you know which one is of the most poorly studied a period about which scientists

02:28know almost nothing especially about the animals that lived at that time this is the

02:36Irvingtonian North American land mammal age it lasted from about 1.6 million to

02:44250,000 years ago scientists have very few fossils that belong to this time but

02:51recently everything has changed in the USA there's the Steinhatchee River which

02:58stretches for several tens of miles in the area of Big Bend Florida and just 500,000

03:04years ago there was a sinkhole instead of the river this is a hole in the ground

03:10that forms when water dissolves the upper rock this rock is often limestone sink

03:16holes appear in places with a lot of precipitation sometimes these pits can be

03:22invisible they look like ordinary ground but the soil in them is loose and can

03:26easily collapse if you accidentally get into a sinkhole people will hear your

03:31screams and help you but in the distant past about half a million years ago when

03:37animals got there they couldn't get out of the pit so it became their grave after

03:43many many years a river appeared here and then several fossil collectors decided to

03:49check out this place and discovered a real paleontological treasure in it they

03:55plunged into the river and reached the bottom there in the murky water they saw

04:00horse teeth sticking out of the sediment it'd be pretty scary to find for many of

04:05us but for these guys it was the jackpot after the teeth they found a hoof

04:11shaft and the skull of an unusual animal at that moment the collectors realized

04:17they had made a major discovery over the years the sinkhole at this place had been

04:23filled with sedimentary rocks then the river compacted all this mass which made

04:29it possible to keep everything inside the sinkhole in good condition many animals

04:35got trapped in this pit half a million years ago and only now have people managed

04:39to get them out more precisely what's left of them divers have found more than 500

04:46fossils belonging to ancient animals including unknown species they got well

04:52preserved bones of ancient horses giant armadillos sloths and a new species of tapir

05:00the Florida Museum examined the remains and determined that they belonged to the

05:05poorly studied Irvingtonian North American land mammal age most of all

05:10scientists were struck by two finds in this collection the first was the remains of a

05:16giant armadillo like creature and the second was the skull of an ancient tapir in case you

05:23didn't know this is a very cute pig like mammal that has a short trunk like an elephant divers in

05:30Florida found the remains of a distant ancestor of this animal which may be a new unknown species

05:36most of the fossils in the sinkhole belong to early cabaline horses a subgroup that includes modern

05:44domestic horses the remains of horses are so well preserved that scientists have seen signs of wear on

05:51their teeth this will allow experts to understand the diet of these ancient creatures we often hear news

05:59about people finding the remains of ancient animals or dinosaurs in caves ravines or at the bottom of

06:05lakes but imagine if they found such remains in a museum it all started in the early 2000s north of the

06:14Florida border in southwest Georgia there was a mine where workers mined clay one day they found the

06:21remains of some ancient animals and gave them to the Florida Museum of Natural History there these

06:28remains lay in storage waiting in the wings and then one day some guy started sorting them out and

06:35noticed a mysterious vertebra of an unknown animal this little grab caught the guy's attention so he returned

06:43to it over and over again he studied it trying to figure out what species the bone belong to one day

06:51he realized the bone belonged to an unknown extinct lizard species that looked like a tegu you've

06:59probably seen these predatory creatures that looked like monitor lizards so the age of the bone was

07:06about 15 to 17 million years old let's wrap up our video with something weird you see this piece of

07:15amber colored stone with stripes or is it not the stone it looks like an ancient seashell

07:21so right now you're looking at the oldest fossil in history it's a stromatolite and its ages you

07:28won't believe it make a guess a hundred million years five hundred million years one billion no this

07:37fossil is about 3.4 billion years old it represents one of the earliest forms of life on earth no not the

07:45stone itself stromatolite is just a playground the early form of life here is these thin strips

07:52they're called cyanobacteria tiny single-celled creatures

07:58okay what about the remains of something bigger some ancient animals for example meet the trilobites

08:06they lived here during the cambrian period which began about 500 million years ago this is the

08:13time when many invertebrates and fish began to appear their exoskeletons helped the trilobites stay

08:19remarkably well preserved considering their age they were arthropods that looked like something between

08:26a spider a scorpion and a mutant from another galaxy these animals lived for a very long time and people find

08:34their remains almost all over the world they appeared at the very beginning of the cambrian period

08:41survived it and became extinct at the end of the permian period during the permian mass extinction

08:47when about 90 percent of all living beings were wiped off the face of the earth these creatures

08:53swam in open water burrowed into the sea floor or crawled along it they lived like predators and

09:00scavengers the front of the animal was protected by a strong head shield it had crescent-shaped eyes

09:07and a calcified plate on its lower body this plate covered its esophagus and mouth it had several pairs

09:15of legs growing from its body the trilobite could also curl up into a ball like a wood louse

09:23that's it for today so hey if you pacified your curiosity then give the video a like and share it
