The clade of plant-eating dinosaurs known as sauropods includes dinosaurs with long necks. Sauropods have long necks, similarly long tails, thick bodies, and tree trunk-like legs that are characteristic of the group. The sauropods, including Diplodocus and Brachiosaurus, are some of the world’s biggest creatures to have ever lived.
Sauropods existed until the late Cretaceous extinction, when they first emerged in the late Triassic period. Let’s look at some of the long-necked sauropods that lived throughout the dinosaurs’ reign.
Facts About the Giraffe-like Dinosaur
During the mid- to late Jurassic Period, Brachiosaurus was a unique dinosaur that lived from 155.7 million to 150.8 million years ago. The dinosaur did not resemble any of the others that roamed the region, and specimens have been found primarily in the fossil-rich Morrison Formation in North America.
It had longer forelegs than hind legs, and its lengthy neck made it resemble a giraffe. Brachiosaurus is derived from the Greek word for “arm lizard.”
Warm-blooded animals, such as Brachiosaurus, were likely present. Gigantotherms, or creatures with huge size that enabled them to maintain high body temperatures, are said to have included Brachiosaurus and other sauropods.
According to this hypothesis, Brachiosaurus had a body temperature of up to 113 degrees Fahrenheit (45 degrees Celsius). By measuring the ratios of specific isotopes (atoms of elements having a different number of neutrons) in Brachiosaurus teeth, scientists were able to calculate the dinosaur’s temperature to be 100.8 F (38.2 C) in 2011.
Brachiosaurus had behavioral or physiological features that allowed them to stay cool despite their enormous size, according to the research, which was published in the journal Science.
Because most size estimates for the dinosaur come from fossils of what was thought to be its African form, B. priscus, it’s unclear how large Brachiosaurus actually was. Brancai is the name of a genus of plants.
However, Michael Taylor, a paleontologist, reanalyzed the fossils of B-brancai and B-altithorax (the North American species) and classified them as Giraffatitan brancai in a 2009 study published in the Journal of Vertebrate Paleontology. While the fossils of both G-brancai and B-altithorax came from specimens that weren’t fully developed, Taylor subsequently calculated that B-altithorax was around 82 feet (25 meters) long.
According to a 2014 study published in PLOS Biology, Brachiosaurus may have weighed around 62 tons (56 metric tons).
Brachiosaurus was regarded the biggest sauropod ever when it was found in 1903, but subsequent research has shown that other sauropods may have been bigger and heavier than Brachiosaurus.
What is a Dinosaur with a Long Neck Called?
Sauropods are the name for the long-necked dinosaurs. The term Sauropoda is derived from the Greek term meaning “lizard-footed,” which was first used in 1878 by a paleontologist called O. C is a programming language that can be used to write programs. Marsh is a common name for boys and girls.
Dinosaur Books is a name I’ve heard before, so I’ll give you a quick heads-up about them. I got information for this article from a variety of sources, including numerous internet sites and publications. Nonetheless, books provide the most reference information.

Sauropods have “long necks, long tails, tiny heads (in comparison to the rest of their body), and four thick pillar-like legs,” according to Wikipedia. They include the world’s largest creatures to have ever lived on land, as well as the species with the world’s biggest sizes.
Sauropod dinosaurs lived all over the globe, and paleontologists believe that the oldest fossils date from the early Jurassic and extend into the late-Cretaceous epoch. Fossil specimens of Sauropod dinosaurs may be found all over the world.
What did Brachiosaurus eat?
The dinosaur’s snout was broad, and the jawbones were robust, with spoon-shaped teeth that were ideally suited for removing vegetation.
Coniferous trees, gingkoes, and cycads were most likely eaten by Brachiosaurus. According to a 2008 research published in the Royal Society B, adult sauropods, including Brachiosaurus, had to consume up to 400 kilograms (880 pounds) of dry plant material each day. Brachiosaurus’ teeth were well-suited to stripping vegetation but not breaking up big pieces of plants, according to scientists.
Traveling in herds, Brachiosaurus is thought to have moved on after depleting the vegetation in a given region. They may have supplemented their diets with vegetation at lower levels (“low browsing”) while the food supply dwindled, while it is assumed that they stripped trees of their vegetation (“high browsing”).
Wilkinson and his colleague Graeme Ruxton examined whether low browsing was an energetically efficient choice for sauropods in 2011, allowing them to eat a wider range of food without having to shift their whole body.
Low browsing costs Brachiosaurus 80% less than dinosaurs with shorter necks, according to a study published in the journal Biology Letters. With its roughly 30-foot (9-meter) long neck, low browsing costs Brachiosaurus 80%.
It’s very difficult to figure out if they are high browsers or low browsers, Wilkinson said, adding that this doesn’t necessarily indicate the dinosaurs were focused on low browsing instead of (or in addition to) high browsing.
Paleontologists do not believe that Brachiosaurus could rear up on its hind legs, as seen in the film “Jurassic Park.”
Heinrich Mallison, a paleontologist, stated in an assessment issued in “Biology of the Sauropod Dinosaurs(opens in new tab)” (Indiana University Press, 2011) that Brachiosaurus’ odd body form and limb proportions made this feat hard and very energetically costly.
Why Did Dinosaurs Have Long Necks, and What is the Biggest Long Neck Dinosaur?
Several fields of study have grown and evolved as a result of technological advancements and recent bioinformatics advances.
When it comes to studying dinosaurs, that applies as well. Nowadays, paleontologists and other dinosaurs fossils enthusiasts are more interested in what features and habitats the dinosaurs had for all discovered dinosaur species, rather than just skeletons.
During the Mesozoic Era, about million years ago, there were several different long-neck dinosaur species. In the list below, you’ll find a variety of sauropods. Let’s learn more about them together!
Since it’s a long-neck dinosaur with spiky horns, the La Amarga lizard is one of a kind. Despite having a short neck when compared to most sauropods, this Early Cretaceous dinosaur is still formidable.
Its neck spines, according to paleontologists, may have been used as a defensive mechanism.
D. had four large, sturdy legs to support its long neck and whip-like tail, and lived 150 million years ago during the late Jurassic period. It weighed about 16 tons and measured approximately 98 feet in length. In 1877, it was found in North America for the first time.
The term Diplodocus comes from neo-Latin, and it refers to the dinosaur’s double-beamed chevrons (bones located on the bottom of the tail in many reptiles). Between 104 million and 152 million years ago, the dinosaur lived in the late Jurassic period.
It was discovered alongside Apatosaurus, Brachiosaurus, and Camarasaurus in the Morrison formation. The Diplodocus was a really big dinosaur, and it is one of the biggest known. The dinosaur is thought to have a total length of 24 meters or 79 feet, and a mass of around 12 metric tons, according to estimates.
The caudal vertebrae that make up the dinosaur’s extremely lengthy tail were thought to have served a variety of purposes, ranging from defense to balance. The spines on the tail might have served a defensive function, and the length of it might have helped to balance the weight of the neck.
During the Late Jurassic era, the Apatosaurus was thought to have lived approximately 150 million years ago. The Morrison Formation, which today comprises sections of Oklahoma, Wyoming, Utah, New Mexico, and Colorado in the United States, was where the dinosaur was found.
The dinosaurs were generally thought to be between 21 and 22.8 m (69 and 75 ft) long with a weight of 16.4 to 22.4 tons, according to most estimations. The skull of the apatosaurus is similar to that of other dinosaurs like the Apatosaurus and the Brachiosaurus, and it has frequently been mistaken with those of other sauropods.
The Ojo Alamo lizard is North America’s largest sauropod, but did you know? This huge long-necked dinosaur grew to be as tall as 98 feet and weighed over 72.6 metric tons. Its huge body was supported by its lengthy, thick legs.
The Alamosaurus existed in the Ojo Alamo Formation of New Mexico during the Late Cretaceous epoch.
Camarasaurus got its name from the holes in its vertebrae, which were discovered in 1877 and mean “chambered lizard.” During the Jurassic period, Camarasaurus lived in North America. Camarasaurus was a herbivore that chewed stones to process food material, as evidenced by fossils, similar to certain current birds. Camarasaurus was roughly 20 tons in weight and measured around 59 feet in length.
The Camarasaurus’ vertebrae have large holes or chambers in them, which gives the name “chambered lizard” a rough translation. The Camarasaurus, like the Brachiosaurus and Apatosaurus, was discovered in the Morrison Formation and lived somewhere between 155 to 145 million years ago.
The Camarasaurus have some of the most well-preserved sauropod bones, which allows for more precise predictions. For the biggest species of the genus, C., it is predicted that the dinosaurs were around 23 meters long and weighed around 51 tons. The last word is the (supremus).
The Brachiosaurus lived during the Late Jurassic period, roughly 154 to 153 million years ago, and is arguably one of the most well-known dinosaurs in the world.
It was found in the Morrison Formation, much like the Apatosaurus. Brachiosaurus is thought to have a length of around 20 to 21 meters (66 to 69 feet) and a weight of 35 metric tons to 58 metric tons.
The fact that the most complete specimen is likely a juvenile adds to the mystery of the dinosaur’s size. The Brachiosaurus’ neck is thought to have 13 long cervical bones, allowing it to accessed vegetation that was possibly as high as 9 meters (30 feet) off the ground.
According to the American Museum of Natural History (AMNH), the Argentinosaurus is one of the world’s largest long-neck dinosaurs.
This massive Late Cretaceous creature weighed 180,000 pounds when it was discovered in Argentina! Throw in the fact that it has a 130-foot total length, and you have an amazing creature.
The name Ultrasaurus means “bigger lizard” in Latin. During the cretaceous epoch, Ultrasaurus lived in Korea between 110 million and 100 million years ago. Ultrasaurus was an herbivore, just like other quadrupedal long-necked dinosaurs.
When the AMNH first displayed the Brontosaurus excelsus to the public in 1905, it lived up to its name. With over 72 feet of spectacular dinosaur bones from head to tail and robust legs, the “thunder lizard” captivated everyone’s attention.
While the Brontosaurus grabbed onto trees, its hind legs may have been employed to help support its bulk.
As far as sauropods go, the Haplocanthosaurus was rather modest. It lived from 155 million to 152 million years ago, according to the Morrison Formation’s lowest layer.
The dinosaur was thought to be around 14.8 meters or 50 feet long and 12.8 metric tons in weight, according to estimates of the Morrison formation specimens.
Some studies have found Haplocanthosaurus to be a primitive macronarian (more primitive than other sauropods), while others have suggested it could be a primitive diplodocoid and closer to the Diplodocus in nature, according to phylogenetic attempts at determining their relationship.
Anatomical traits and habitat, such as Euhelopus zdanskyi, are often used to inspire dinosaur names.
Its name alludes to the location where it was unearthed, a marsh, and was named after the sauropod’s foot, which resembled Swedish shoes called Its.
The Austrian student Zdansky, who discovered the fossils in 1923, bears the surname Zdansky.
During the Late Cretaceous epoch about 70 million years ago, Opisthocoelicaudia was a kind of sauropod. In Mongolia’s Gobi desert, the dinosaurs were discovered. While it is classified as a Titanosauria, the dinosaur may have been closely connected to Alamosaurus.
The Opisthocoelicaudia weighed between 8.4 and 22 tons and was 11.4 m (or 37 feet) to 13 m (43 feet) in length, making it one of the smallest sauropods known. The best specimen is a reasonably well-preserved skeleton lacking the neck and head, which is missing a skull for the others.
The Titanosaurs include the Patagotitan, as well as the Argentinosaurus. These are a collection of creatures formed from the world’s largest creatures that have ever existed.
With a neck that was almost twice as long as a human’s, this Argentine dinosaur had a 102-foot length. It existed 102 million years ago, during the Late Cretaceous epoch.
The short limbs and relatively short neck of Saltasaurus set it apart from other sauropods. It existed roughly 70 million years ago, in the Late Cretaceous epoch. The Lecho Formation in Argentina yielded the discovery of the dinosaur.
The sauropod was small for members of the clade, despite its enormous size compared to most modern animals. The dinosaur was hypothesized to have been approximately 12.8 meters or 42 feet long and weighed approximately seven tons. At Utah’s North American Museum of Ancient Life, there is a preserved Saltasau egg on display for visitors.
