Numerous macronarian sauropods; from left to right, Camarasaurus, Brachiosaurus, Giraffatitan, and Euhelopus.
Lets not get ahead of ourselves– lets look at what these long-neck dinosaurs were like.
Dinosaurs with long necks (most commonly, sauropods) have actually amazed our imagination given that we initially discovered them. However, long neck dinosaurs are more than just a curiosity– they played an essential role in their ecosystem. These dinosaurs also show what remarkable outcomes evolution can have over the years.
What are sauropods?
Argentinosaurus, potentially the largest sauropod to wander the land.
The sight of such a dinosaur must have been awesome. Envision walking in a lush, green forest 150 million years ago. You hear a remote rumble. You take a look around, and you dont see anything; and then, you search for. Emerging from the foliage, you see it– a big dinosaur stretching its long neck to graze from treetops like a giraffe, high above the imposing tree zone.
They are without a doubt the largest terrestrial dinosaurs in the Earths history, and may have even been larger than the blue whales. For contrast, the longest terrestrial animal alive today, the African elephant, can just reach lengths of 7.3 meters (24 feet).
These spectacular types of dinosaurs, organized in a clade called sauropods, have actually captivated us for generations, and youve most likely seen them included in whatever from books to smash hit films.
The sauropods most defining characteristic was their size. The smallest sauropods had to do with 5 to 6 meters, or 20 feet long, and were probably the largest animals in their ecosystem. However the biggest sauropods, like the Supersaurus, came in at 33 to 34 meters (108 to 112 feet) long. Diplodocus, the old record holder, was likewise long. Theres even some speculation that a dinosaur called Amphicoelias fragillimus ( now Maraapunisaurus) may have determined a whopping 58 meters (190 ft) long (although this is debated).
Attempt to think of a number of dinosaurs strolling the Mesozoic land. The terrifying Tyrannosaur probably springs to mind, as do the magnificent triceratops and stegosaurus. But the chances are youre likewise considering a various type of dinosaur: one that has a long neck.
Sauropods were herbivorous (plant-eating), generally quite long-necked quadrupeds (four-legged). These dinosaurs had actually little heads compared to their massive bodies and normally sported long tails. Their back legs were straight and durable, ending in feet that resembled clubs. These feet had 5 toes, but just the innermost 3 or often 4 had claws. Their front legs were leaner, like pillars implied for bearing weight.
Sauropod development– how the long neck dinosaurs came to be
There is still a great deal of argument about the long necks of these dinosaurs. What is clear is that sauropods had a number of evolutionary modifications to be able to work with this uncommon biology. They progressed vertebrae that consisted of 60% of air, and specialized air sacs assisted in the circulation of air through the necks, helping the dinosaurs to take in.
According to some computer system models of sauropod necks, sauropod necks were capable of purging large feeding locations without requiring to move their bodies, which was a benefit. The exact same research study concluded that they would have been unable to be withdrawed to a position much above the shoulders for checking out the area or reaching higher.
Being huge suggested they had no major predators, at least as adults. The long necks implied they might consume a great deal of food around them without moving too much. Getting to this point needed a lot of adjustment and a lot of biological changes.
Researchers dont in fact settle on how sauropods held their necks and heads, and the postures they could attain in life. Their necks were so high that even just pumping blood to that height would have been challenging if they held their necks up straight. But the long necks must have provided an evolutionary advantage, otherwise they wouldnt have actually emerged.
Long-necked dinosaurs didnt simply appear over night. As they transitioned to a four-legged position, their necks elongated, providing them with an advantage in reaching for greenery.
A specific sauropod group, called the titanosaurs became the dominant long-necked dinosaurs in the late Cretaceous. As the name indicates, the titanosaurs were undoubtedly titanic. They were the last enduring group of long-necked sauropods and reached well over 30 meters in length– maybe even up to 40 meters.
The name for the dinosaur order Sauropoda was created by Othniel Charles Marsh in 1878, and is obtained from Ancient Greek, indicating “lizard foot”. Paleontologists would discover traces of these huge dinosaurs more frequently than actual fossils. The oldest sauropod we know clearly dates from the early Jurassic– 228 million years ago. Throughout the Jurassic, they ended up being increasingly typical. Then, by the Cretaceous (the duration when dinosaurs like triceratops or T-Rex existed), they were prevalent.
Sauropod habitat and communities
The environment of sauropods wasnt almost the landscape and climate; it also consisted of other living animals. Sauropods shared their world with a diverse selection of organisms, from other herbivorous and carnivorous dinosaurs to early mammals, reptiles, amphibians, and a variety of flying and marine reptiles.
Depiction of Alamosaurus, a sauropod, in its environment.
The dominant plants during the Mesozoic consisted of ferns, horsetails, cycads, conifers, and ginkgoes. Flowering plants (angiosperms) began to appear and diversify in the Cretaceous. Sauropods would have delighted in these plants, utilizing their peg-like teeth to strip plant life, and their long necks permitted them to feed both on the ground and from trees.
The continents during the Mesozoic were in different positions than they are today. The land was united in a supercontinent called Pangaea, which started to break apart throughout the time of the sauropods. This produced vast coastlines and inland locations with unique environments.
The Mesozoic Era, specifically throughout the Early and jurassic Cretaceous, was usually warmer than today. There were no polar ice caps, so international temperature levels were higher, causing a warm and damp environment in lots of parts of the world.
Tying the Long Neck to Modern Animals
Today, no animals come close to the grandeur of these long-necked dinosaurs. If you want a modern-day comparison, think about the giraffe. Giraffes, like their ancient equivalents, have actually adapted long necks to reach plant life thats out of grab other animals.
Its essential to keep in mind that giraffes are not related to any long-neck dinosaur. The giraffes are mammals, dinosaurs were reptiles.
Keep in mind: dinosaurs with long necks and mammals with long necks are completely unassociated.
How sauropods are named? Its not just about size
Contrast
Sure, these dinosaurs were massive, but their names often inform us more than just their measurements. Originated from Greek and Latin roots, these names provide hints to the dinosaurs qualities, discovery areas, and even the researchers who found them. Youll come across names like Diplodocus, which suggests “double beam,” and Apatosaurus, which intriguingly implies “misleading lizard.”
The Famous Brachiosaurus
Its name equates to “equip lizard,” describing its unusually long front limbs. Unlike many long-necked dinosaurs that held their necks out horizontally, Brachiosaurus held its neck more vertically, enabling it to reach greenery other dinosaurs could not.

In the world of extreme, no dinosaur quite compares to Argentinosaurus. Belonging to what is now Argentina, this leviathan most likely reached lengths of up to 100 feet. Not remarkably, its name indicates “silver lizard,” named after Argentina, the “land of silver.” Due to the fact that it has one of the longest names amongst dinosaurs, Argentinosaurus is not just a star for its size however likewise!
The misunderstood Apatosaurus

When notoriously called Brontosaurus, Apatosaurus was a massive dinosaur that lived during the Late Jurassic period. It had a long neck and tail, with a stout body. Its length rose to about 75 feet (23 meters), and it roamed the floodplains of what is now North America. Despite its huge size, its neck was versatile and so long that it most likely fed on ferns and low-lying plant life.
The spectacular Diplodocus
Identified by its very long neck and tail, Diplodocus is among the most iconic sauropods. It lived throughout the Late Jurassic duration and reached lengths of as much as 100 feet (30 meters). Its whip-like tail might have served as a protective mechanism against predators, while its peg-like teeth were fit for removing soft vegetation.

Coming from the Late Cretaceous duration, Titanosaurus is a genus that resided in what is now India and South America. Not as long as some of its relatives, Titanosaurus was still a large animal, with particular types potentially reaching up to 40 feet (12 meters) in length. Its remains have been discovered in numerous areas, suggesting it adjusted to various environments.
Unveiling Lesser-Known Giants
Beyond the A-listers like Brachiosaurus and Argentinosaurus, there are lesser-known but equally appealing long-necked dinosaurs. This dinosaur had one of the longest necks relative to its body size.
There were a lot of long-necked dinosaurs– a testament to how reliable this evolutionary course should have been.
