1 00:00:00,000 --> 00:00:04,000 Welcome to Dynamite Adventures. 2 00:00:04,000 --> 00:00:13,000 Journey back in time as we explore the fascinating world of dinosaurs and prehistoric life. 3 00:00:13,000 --> 00:00:21,000 Today, we're taking a deep dive into the world of one of the coolest dinosaurs ever. 4 00:00:21,000 --> 00:00:22,000 Oh yeah. 5 00:00:22,000 --> 00:00:23,000 The Brontosaurus. 6 00:00:23,000 --> 00:00:24,000 You got that right. 7 00:00:24,000 --> 00:00:27,000 Well, its name gives us a pretty good clue. 8 00:00:27,000 --> 00:00:30,000 The Brontosaurus means Thunder Lizard. 9 00:00:30,000 --> 00:00:31,000 That sounds super cool. 10 00:00:31,000 --> 00:00:32,000 It does. 11 00:00:32,000 --> 00:00:33,000 But why would they call it that? 12 00:00:33,000 --> 00:00:35,000 Did it make thunder sounds? 13 00:00:35,000 --> 00:00:37,000 Not exactly, but close. 14 00:00:37,000 --> 00:00:44,000 Scientists think that when this gigantic dinosaur walked, the ground would shake so much that it probably sounded like thunder rumbling. 15 00:00:44,000 --> 00:00:49,000 Can you imagine how cool that would be to hear the ground shaking as a giant walk by? 16 00:00:49,000 --> 00:00:51,000 So how big was this Thunder Lizard? 17 00:00:51,000 --> 00:00:52,000 Get ready to be amazed. 18 00:00:52,000 --> 00:00:55,000 A Brontosaurus could grow to be over 70 feet long. 19 00:00:55,000 --> 00:00:56,000 That's longer than a school bus. 20 00:00:56,000 --> 00:00:59,000 And they weighed somewhere between 15 and 20 tons. 21 00:00:59,000 --> 00:01:00,000 Really? 22 00:01:00,000 --> 00:01:03,000 That's like having four or five elephants standing on one spot. 23 00:01:03,000 --> 00:01:05,000 So what did this giant look like? 24 00:01:05,000 --> 00:01:07,000 Did it have sharp teeth and claws? 25 00:01:07,000 --> 00:01:08,000 Like a T-Rex? 26 00:01:08,000 --> 00:01:09,000 Not quite. 27 00:01:09,000 --> 00:01:12,000 The Brontosaurus was a gentle giant. 28 00:01:12,000 --> 00:01:13,000 Picture this. 29 00:01:13,000 --> 00:01:18,000 A long, long neck stretching high up into the air. 30 00:01:18,000 --> 00:01:21,000 A big round body, like a giant bathtub. 31 00:01:21,000 --> 00:01:22,000 Wow. 32 00:01:22,000 --> 00:01:26,000 And a strong, powerful tail that could probably whip back and forth. 33 00:01:26,000 --> 00:01:27,000 Cool. 34 00:01:27,000 --> 00:01:33,000 It had sturdy legs, like pillars holding up a building, and a surprisingly small head for such a big dinosaur. 35 00:01:33,000 --> 00:01:35,000 Oh, and its teeth. 36 00:01:35,000 --> 00:01:38,000 They were more like pegs perfect for stripping leaves off branches. 37 00:01:38,000 --> 00:01:41,000 Okay, so a gentle giant with a super long neck. 38 00:01:41,000 --> 00:01:46,000 Brontosaurus lived way back in the late Jurassic period, about 150 million years ago. 39 00:01:46,000 --> 00:01:47,000 Wow. 40 00:01:47,000 --> 00:01:49,000 Back then, North America where they lived was a very different place. 41 00:01:49,000 --> 00:01:55,000 Imagine lush forests filled with giant ferns and all sorts of yummy plants for our Brontosaurus friend to munch on. 42 00:01:55,000 --> 00:01:58,000 Speaking of munching, what did something that big eat all day long? 43 00:01:58,000 --> 00:02:00,000 Did it chomp on other dinosaurs? 44 00:02:00,000 --> 00:02:05,000 Actually, even though it was huge, the Brontosaurus was an herbivore, meaning it only ate plants. 45 00:02:05,000 --> 00:02:06,000 Really? 46 00:02:06,000 --> 00:02:07,000 Can you believe that? 47 00:02:07,000 --> 00:02:12,000 To fuel that giant body, it spent all day munching on plants. 48 00:02:12,000 --> 00:02:14,000 Wow, that must have been a lot of plants. 49 00:02:14,000 --> 00:02:17,000 But how did it eat if its teeth were like pegs? 50 00:02:17,000 --> 00:02:19,000 Did it chew its food like we do? 51 00:02:19,000 --> 00:02:21,000 That's a great question. 52 00:02:21,000 --> 00:02:24,000 You see, the Brontosaurus didn't actually chew its food. 53 00:02:24,000 --> 00:02:27,000 It swallowed those leaves whole and get this. 54 00:02:27,000 --> 00:02:30,000 They had special stones in their stomachs called gastroliths. 55 00:02:30,000 --> 00:02:31,000 Gastroliths? 56 00:02:31,000 --> 00:02:32,000 Gastroliths. 57 00:02:32,000 --> 00:02:37,000 They're like little rocks that helped grind up the leaves in their tummy like a rock tumbler inside. 58 00:02:37,000 --> 00:02:38,000 Isn't that amazing? 59 00:02:38,000 --> 00:02:39,000 That's incredible. 60 00:02:39,000 --> 00:02:43,000 So we know what they ate, but how did something so big move around? 61 00:02:43,000 --> 00:02:45,000 Did it run super fast or did it kind of lumber around? 62 00:02:45,000 --> 00:02:49,000 Well, think of it this way, a Brontosaurus walking on all fours with a slow, lumbering gate, 63 00:02:49,000 --> 00:02:52,000 kind of like an elephant, only much, much bigger. 64 00:02:52,000 --> 00:02:55,000 They weren't built for speed, but they were definitely built for power. 65 00:02:55,000 --> 00:02:59,000 Okay, so slow and steady wins the race, or in this case, the yummy leaves. 66 00:02:59,000 --> 00:03:02,000 But what if a mean dinosaur tried to attack it? 67 00:03:02,000 --> 00:03:04,000 Could it fight back? 68 00:03:04,000 --> 00:03:06,000 That's where that powerful tail comes in. 69 00:03:06,000 --> 00:03:09,000 Scientists think the Brontosaurus could use its long tail like a whip, 70 00:03:09,000 --> 00:03:15,000 either to defend itself against predators or maybe even to communicate with other Brontosaurus. 71 00:03:15,000 --> 00:03:18,000 Whoa, that would definitely scare me away. 72 00:03:18,000 --> 00:03:22,000 So they used their tails for defense, but did they have any other ways to stay safe? 73 00:03:22,000 --> 00:03:24,000 Well, they weren't loners. 74 00:03:24,000 --> 00:03:27,000 Brontosaurus probably traveled in herds kind of like a big family. 75 00:03:27,000 --> 00:03:32,000 Being in a group would have made it much harder for predators like the Allosaurus to attack them. 76 00:03:32,000 --> 00:03:33,000 That makes sense. 77 00:03:33,000 --> 00:03:34,000 Safety in numbers, right? 78 00:03:34,000 --> 00:03:35,000 Yeah. 79 00:03:35,000 --> 00:03:39,000 Wait a minute, I remember hearing somewhere that the Brontosaurus wasn't really a real dinosaur. 80 00:03:39,000 --> 00:03:40,000 What's up with that? 81 00:03:40,000 --> 00:03:43,000 Ah, you're talking about the great Brontosaurus mix-up. 82 00:03:43,000 --> 00:03:46,000 For a long time, scientists thought that the bones they found of a Brontosaurus 83 00:03:46,000 --> 00:03:49,000 actually belonged to another dinosaur called a Patosaurus. 84 00:03:49,000 --> 00:03:52,000 Wait, so there's like a big dinosaur identity crisis going on. 85 00:03:52,000 --> 00:03:53,000 Exactly. 86 00:03:53,000 --> 00:03:58,000 It all started way back in the 1870s during a time called the Bone Wars. 87 00:03:58,000 --> 00:04:03,000 Imagine scientists racing to find new dinosaur bones and give them names. 88 00:04:03,000 --> 00:04:07,000 Sometimes they even made mistakes like mixing up the Brontosaurus with the Apatosaurus. 89 00:04:07,000 --> 00:04:09,000 Wow, that sounds kind of crazy. 90 00:04:09,000 --> 00:04:11,000 So what happened to the Brontosaurus name? 91 00:04:11,000 --> 00:04:18,000 Well, in 1879, a scientist named Othniel Charles Marsh found some bones and called them Brontosaurus. 92 00:04:18,000 --> 00:04:24,000 But later, other scientists thought those bones were just a different type of Apatosaurus. 93 00:04:24,000 --> 00:04:27,000 Sadly, the name Brontosaurus was dropped for a while. 94 00:04:27,000 --> 00:04:29,000 Oh no, we're Brontosaurus. 95 00:04:29,000 --> 00:04:31,000 So does that mean it was gone forever? 96 00:04:31,000 --> 00:04:33,000 Not quite. The story gets even better. 97 00:04:33,000 --> 00:04:37,000 In 2015, some really smart scientists took another look at all those bones 98 00:04:37,000 --> 00:04:39,000 and made an awesome discovery. 99 00:04:39,000 --> 00:04:46,000 They realized there actually were enough differences to make the Brontosaurus its own unique dinosaur again. 100 00:04:46,000 --> 00:04:50,000 Yay! The Brontosaurus is back! That's so awesome. 101 00:04:50,000 --> 00:04:52,000 I bet those Brontosaurus were super happy. 102 00:04:52,000 --> 00:04:56,000 So if they were real, did they make those loud scary roars here in movies? 103 00:04:56,000 --> 00:04:58,000 That's a great question. 104 00:04:58,000 --> 00:05:02,000 You know, even though we see dinosaurs roaring in movies, we don't know for sure what sounds they made. 105 00:05:02,000 --> 00:05:07,000 Scientists think that instead of roaring, Brontosaurus might have made low, deep, rumbling noises, 106 00:05:07,000 --> 00:05:10,000 kind of like elephants or whales do today. 107 00:05:10,000 --> 00:05:13,000 Hmm, low rumbles. That's still pretty cool. 108 00:05:13,000 --> 00:05:18,000 Okay, so besides its giant size, what else made the Brontosaurus so special? 109 00:05:18,000 --> 00:05:23,000 Well, think about it. Its size and strength alone made it a force to be reckoned with. 110 00:05:23,000 --> 00:05:28,000 Most predators probably wouldn't even try to mess with a full-grown Brontosaurus. 111 00:05:28,000 --> 00:05:32,000 Plus, their long necks let them reach food that other dinosaurs couldn't, 112 00:05:32,000 --> 00:05:35,000 giving them a big advantage at the prehistoric dinner table. 113 00:05:35,000 --> 00:05:38,000 So they were like the kings and queens of the salad bar. 114 00:05:38,000 --> 00:05:41,000 Exactly. And here's another cool fact. 115 00:05:41,000 --> 00:05:46,000 Scientists believe that their necks might have had special air sacs inside, kind of like balloons. 116 00:05:46,000 --> 00:05:48,000 Air sacs in their necks, what were those for? 117 00:05:48,000 --> 00:05:52,000 Well, imagine carrying around a neck that long. It would be super heavy. 118 00:05:52,000 --> 00:05:55,000 The air sacs would have made their necks lighter and easier to lift, 119 00:05:55,000 --> 00:05:57,000 almost like they were floating a little bit. 120 00:05:57,000 --> 00:05:59,000 Wow, a giant floating neck. 121 00:05:59,000 --> 00:06:00,000 Yeah. 122 00:06:00,000 --> 00:06:04,000 That's amazing. They were strong, they had cool air sacs, and they were super-duper big. 123 00:06:04,000 --> 00:06:07,000 No wonder the Brontosaurus is one of the most famous dinosaurs ever. 124 00:06:07,000 --> 00:06:10,000 Absolutely. You see them in books, toys, and even cartoons. 125 00:06:10,000 --> 00:06:13,000 The Brontosaurus has definitely captured our imaginations. 126 00:06:13,000 --> 00:06:15,000 And for a good reason. 127 00:06:15,000 --> 00:06:19,000 I mean, who doesn't love a gentle giant that could shake the ground with its footsteps? 128 00:06:19,000 --> 00:06:22,000 It's a dinosaur that definitely leaves a big impression. 129 00:06:22,000 --> 00:06:26,000 Well, I know one thing for sure. If I could travel back in time, 130 00:06:26,000 --> 00:06:29,000 I would love to see a Brontosaurus in real life. 131 00:06:29,000 --> 00:06:34,000 It would be so cool to watch it munch on leaves and lumber through those ancient forests. 132 00:06:34,000 --> 00:06:39,000 Just imagine seeing a whole herd of these magnificent creatures moving together, their long necks, 133 00:06:39,000 --> 00:06:43,000 swaying like giant treetops. It would be an incredible sight. 134 00:06:43,000 --> 00:06:47,000 Whoa. That gives me goosebumps just thinking about it. 135 00:06:47,000 --> 00:06:50,000 Now it's your turn to use your imaginations. 136 00:06:50,000 --> 00:06:53,000 If you were a Brontosaurus, what kind of plants do you think you would eat? 137 00:06:53,000 --> 00:06:57,000 Would you go for the tallest trees or maybe stick to the tastiest ferns? 138 00:06:57,000 --> 00:06:59,000 And how would it feel to have such a long neck? 139 00:06:59,000 --> 00:07:02,000 Would you use it to reach the highest leaves, peak over mountains, 140 00:07:02,000 --> 00:07:06,000 or maybe even give your friends a gentle nudge? Let your imaginations run wild. 141 00:07:06,000 --> 00:07:09,000 The world of dinosaurs is full of mystery and wonder, 142 00:07:09,000 --> 00:07:12,000 and thanks to amazing scientists and their discoveries, 143 00:07:12,000 --> 00:07:16,000 we get to learn more and more about these incredible creatures all the time. 144 00:07:16,000 --> 00:07:20,000 And who knows, maybe someday some of you listening will become paleo-emologists 145 00:07:20,000 --> 00:07:25,000 and make even more amazing discoveries about the dinosaurs that roamed our planet millions of years ago. 146 00:07:25,000 --> 00:07:29,000 Keep your eyes peeled, your minds curious, and your imaginations roaring. 147 00:07:29,000 --> 00:07:34,000 Because when it comes to dinosaurs, there's always something new and exciting to discover. 148 00:07:34,000 --> 00:07:39,000 And with that, we wrap up our deep dive into the world of the mighty Brontosaurus. 149 00:07:39,000 --> 00:07:41,000 But hey, the fun doesn't stop here. 150 00:07:41,000 --> 00:07:45,000 If you want to learn even more about Brontosaurus or other dinosaurs, 151 00:07:45,000 --> 00:07:49,000 be sure to check out your local library or do some exploring online. 152 00:07:49,000 --> 00:07:53,000 There's a whole universe of dinosaur knowledge out there just waiting to be discovered. 153 00:07:53,000 --> 00:07:57,000 And remember, keep those imaginations running wild. 154 00:07:57,000 --> 00:08:03,000 And don't forget, the coolest fact of all the Brontosaurus, the Thunder Lizard, really did walk the Earth. 155 00:08:03,000 --> 00:08:08,000 Can you believe it?
