 real quick introduction digging for dinosaurs book 1960 I saw somebody mentioned this on a Facebook group I follow called vintage dinosaur pictures yes that is a group I follow was published to go along with the panorama color slide machine has a series of slides with it it looks like what you do is you push the slides through one at a time on one side and then you flip the card over and there are four sets of slides in this series that that match pictures in the book and to go along with the slideshow there's a record recorded by Walter Cronkite you will hear that in the second half of this video and its entirety a an informational insert about how to run the machine as soon as I saw this mentioned on Facebook I went and looked for it on eBay and there it was for a very little money so I snapped it up and you're gonna see the slideshow and hear the record here it has some introductory material here that is not included on the record and the recorded narration is shorter it is more brief than the text that's included with each of the pictures here at first glance there's an awful lot of material about paleontology here rather than just paintings of dinosaurs but the the narration is a typical kind of thing you would find from this era of dinosaur enthusiasm so anyway here's the stuff from Walter Cronkite this is Walter Cronkite speaking taking you back more than 100 million years to the mesozoic age here in our first picture is a strange and unfamiliar earth full of giant ferns steaming marshes dominated by the huge dinosaurs we see towering over the landscape they were kings of all they surveyed for millions of years no man was around to challenge their rule but if the brawniest athlete of today were here in this scene he would be no more than a quick bite in the mighty jaws of the meat-eating allosaurs we see in the center of the landscape looking about hungrily for their next meal they would undoubtedly prefer to dine on the huge brontosaurus in the background safely out of reach in their marsh but they'll probably settle for the spiny ridge stegosaurs in the foreground after a terrible earth-shaking fight which will match their sword-like teeth against the stegosaurs spiky tail now let us move forward in time to picture two where giant ferns once grew in steaming swamps we see today only eroded rock sand and desert plants where are the mighty dinosaurs perhaps the huge fossilized skeleton of one lies somewhere in these very rocks buried for millions of years waiting for us to discover it we're at the beginning of one of the most exciting detective stories in history we meet a leading dinosaur detective or paleontologist in number three dr. Theodore White has shown examining a clue part of the skull of a meat-eating dinosaur eminent paleontologists like dr. White teach us where to look for buried dinosaurs and how to recognize them when we find them and how to take specimens out of their ancient beds let us see what kind of detectives we make as we start out in picture four on our own dinosaur hunt here we have traveled to the American Southwest under in the wilderness of fossil country ahead of us are many days even weeks of searching for evidence of dinosaurs evidence such as we see in number five this is what a fossil looks like it is usually embedded in rock as you can see here they're all kinds of fossil some so tiny they can only be seen with the aid of a microscope but we are after a dinosaur moving to number six we see a member of our party walking out the fossil beds our geologists have found an outcropping of rock from the mesozoic age the age of dinosaurs containing evidence of fossils we'll follow it to find out how the rocks lie hoping to find a dinosaur at the end of the trade in picture seven we find ourselves scrambling up a cliff but we must go where the clues lead us combining the courage and endurance of a mountain climber with the skills and patience of a prospector it's hot and hard work who can blame us for thinking maybe it's time to head back to camp for a cool drink and rest but wait what is that we just passed let's retrace our steps in number eight here it is buried treasure buried for millions of years a fragment of fossilized dinosaur bone thirst and fatigue are forgotten as with hearts pounding we uncover this first piece of evidence in our dinosaur hunt we must be careful with our tools as we remove the overburden of rock from this and the other bones of the skeleton for we feel sure now that the remains of a dinosaur lie buried right at our feet now turn the slide card over here in picture nine we see a scientist cleaning the exposed bones of our specimen with a brush dinosaur detectives must do their work as delicately as police dust for fingerprints at the scene of a crime the slightest blow from a hammer would shatter these ancient bones in number ten we see a specimen being doctored for safe shipment back to the laboratory with the tender care of surgeon putting a broken bone in a cast our experts wrapped the brittle remains of the dinosaur in layers of burlap dipped in plaster even though in this case our patient has been dead for millions of years move now to picture 11 the huge bone you see being excavated here proves that our hunt is even more successful than we had dared hope we came looking for a dinosaur we've discovered one of the largest of them all the mighty Brontosaurus look at the size of that bone it's not hard to believe that the earth troubled with each step this giant took now our specimens carefully plastered and crated we travel in number 12 to the museum laboratory after being unpacked cleaned and shellacked the larger bones are drilled and steel rods inserted to support them for mounting the scattered pieces of our dinosaur is a bit like assembling a giant jigsaw puzzle let's see if our puzzle has worked out as we move to picture 13 here he is all 67 feet to probably the largest kind of animal ever to walk the land in spite of his great size look at the stretch of that neck the vegetarian Brontosaurus was no match for the steam shovel jaws of smaller but fiercer meat-eating dinosaurs who dined on him where cows and cowboys roam the American West today the Brontosaurus provided up to 35 tons of beef on the hook millions of years ago even before the dinosaurs the West swarmed with strange creatures witness our next picture number 14 this is a skeleton of a dimetrodon in the American Museum of Natural History the dimetrodon lived in Texas way before the first Brontosaurus appeared he was seven feet long and pretty large even for a Texan instead of a 10 gallon hat he sported an impressive sail on his back indicated by the huge spines we see sticking up here in picture 15 we see the dimetrodon restored to life in a painting by the famous museum artist the late Charros are night the reason for the sale is not definitely known one theory has it that it was a protective device another that it acted as a radiator providing a cooling surface on hot days and a sun absorbing surface on cold ones but neither theory has been proved move now to number 16 here we see the skeleton of an allosaur rouched over the backbone of a Brontosaurus the hunter and its victim actual tooth marks on this Brontosaurus marks on this Brontosaurus marks on tooth marks that could have been made by the savage bite of an allosaurus picture 17 we see the allosaurus fully restored and in its natural surroundings must have been a fearsome sight as it stalked the land on its powerful hind legs jaws wide open for the attack in the hook like claws of its four feet ready to grasp its prey imagine a dinosaur football team here's a 35 foot long charging fullback guaranteed to make the opposition tremble move now to number 18 here's the skeleton of a stegosaur the so-called plated dinosaur found in Wyoming stegosaurs were walking fortresses huge animals protected by thick skin carrying a deadly four spiked weapon in the tail and armored by the upright triangular plates we see here for a look at a stegosaur fully closed please move to picture 19 it must have had few enemies in spite of its clumsiness as well as being built like a tank it could punch four holes at a time in the height of its enemy with a swing of that powerful spiked tail note the tiny head body as big as an elephant a brain the size of a walnut brawn not brains paid off in the dinosaur age now we come to number 20 here is a restoration of two trachodons or duck bills so-called for reasons that become obvious as we gaze at their broad flattened skull they lived 60 million years after the stegosaurs an age that might be called the twilight of the dinosaurs because during it all the dinosaurs disappeared from the face of the earth the duck bills browsed along the shallows of rivers and lakes as we see here munching on water plants they and other dinosaurs bore their children in the form of eggs in picture 21 we see a sensational find the fossilized skeleton of a dinosaur and some eggs they were discovered by dr. Roy Chapman Andrews of the American Museum of Natural History during an expedition to outer Mongolia the little horn dinosaur in our picture was named after dr. Andrews its full name is Potocera tops and juicy move now to number 22 here are some more dinosaur eggs discovered on the same expedition wouldn't they make a king-sized omelet though when found these eggs were at first thought to be a fossil birds until the scientists discovered hurled up inside some of the shells tiny unhatched dinosaurs in picture 23 we see a restoration of baby dinosaurs just after hatching it may be stretching things to call these little Potocera tops cute but their parents probably wouldn't think much of human babies either it's all in the point of view now let's look at a relative of our little Potocera tops in picture 24 this is a skeleton of the mighty three horn triceratops perhaps the best known of the horned dinosaurs triceratops grew to 30 feet in length and stood eight feet high at the hips compare its eyes with the young lady in the background here it's most remarkable features where it's enormous head and frill making up one-third of its length if you will turn the slide card over we will come to number 25 and a restoration of a triceratops triceratops hooked with its horns when challenged to a battle made short powerful lunges with its head down the two horns over its eyes could impale any enemy such an arrangement must have been very useful for the three horned dinosaur lived in a land inhabited by Tyrannosaurus Rex whom we meet in picture 26 here he is the fiercest most destructive killer the world has ever known Tyrannosaurus Rex standing on thickly muscled hind legs carried his tremendous head 18 to 20 feet above the ground he was 50 feet long from head to tail he weighed some 8 or 10 tons the curved daggers of his teeth were almost 6 inches long no wonder the whole world feared him move now to number 27 for a look at him as he might have appeared in real life Tyrannosaurus Rex is the largest meat-eating animal that ever lived on land this all-time heavyweight champion used a combination of terrible claws and rendling teeth to conquer any opponent its scientific name was well-earned Tyrannus, tyrant, sorus, lizard, Rex, king or king of the tyrant lizards move now to number 28 so far we have seen only reptiles that walked however some of them flew one of the most impressive of these was the one we see here the tyrannodon this giant flying machine wings spread as some 27 feet lived 70 to 100 million years ago it probably glided and soared as much as it flew now let us move to picture 29 to see an ancestor of our modern birds here is a skeleton cast in plaster of the prehistoric bird archaeopteryx fossils of this primitive perching bird were first discovered in Germany many years ago the first discovery was by accident so often happens workmen cutting out ancient limestone blocks from a quarry found the impressions of a feather in one and then an imperfect skeleton of a bird far more primitive than any now in existence in number 30 we see a restoration of this prehistoric bird notice how this strange-looking creature combines features of both birds and reptiles its plumage reminds us of today's birds but see the reptilian teeth and the long reptilian tail with feathers arranged on either side of it move now to picture 31 here is a fossilized botasaur footprint possibly made as the huge vegetarian fled through mud toward open water inside the botasaur footprint is the smaller three-toed track of the meat eating allosaur that was chasing it did the allosaur catch its meal or did the botasaur reach safety in deep water it's a hundred million year old detective story that nobody will ever saw our final picture is a restoration of our botasaur its long snaky neck looming above the ancient marsh plants on constant lookout for an approaching enemy we've learned a good deal as dinosaur detectives we've seen how scientists have been able to reconstruct these giant creatures and their way of life from bits of fossilized bone and impressions in the rock man rules now where once the dinosaur was king before we dismissed the dinosaurs as failures because they became extinct but us consider we've been here at the most a few million years the dinosaurs dominated the world for a hundred and twenty million years we've got a long long way to go
