One of the best-known sauropods, Diplodocus was a very large long-necked quadrupedal animal, with a long, whip-like tail. Quadrupedalism (from Latin meaning "four legs" is a form of land animal locomotion using four legs. Its forelimbs were slightly shorter than its hind limbs, resulting in a largely horizontal posture. The long-necked, long-tailed animal with four sturdy legs has been mechanically compared with a suspension bridge. [4] In fact, Diplodocus is the longest dinosaur known from a complete skeleton. [4] The partial remains of D. hallorum have increased the estimated length, though not as much as previously thought; when first described in 1991, discoverer David Gillete calculated it may have been up to 54 m (177. 05 ft) long, making it the longest known dinosaur (excluding those known from especially poor remains, such as Amphicoelias). Amphicoelias (ˌæmfɨˈsiːliəs meaning 'doubly hollow' from the Greek amphi: "on both sides" and koilos: "hollow concave" Some weight estimates ranged as high as 113 (rather only 50) tonnes (125 US short tons). This article is about the tonne or metric ton For other tons see Ton. The short ton ( S/T) is a unit of mass equal to 2000 lb (around 907 This review was based on recent findings that show that the giant tail vertebrae were actually placed further forward on the tail than Gillete originally calculated. The study shows that the complete Diplodocus skeleton at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania on which estimates of Seismosaurus were based had its 13th tail vertebra come from another dinosaur, throwing size estimates for Seismosaurus off by up to 30%.

While dinosaurs such as Supersaurus were probably longer, fossil remains of these animals are only fragmentary.

The skull of Diplodocus was very small, compared with the size of the animal, which could reach up to 35 m (115 ft),[6] of which over 6 m (20 ft) was neck. The largest organism found on earth can be measured using a variety of methods [7] Diplodocus had small, 'peg'-like teeth that pointed forward and were only present in the anterior sections of the jaws. In fields of Anatomy, anatomical terms of location are descriptive terms to help identify relative positions or directions within a species [8] Its braincase was small. The neck was composed of at least fifteen vertebrae and is now believed to have been generally held parallel to the ground and unable to have been elevated much past horizontal.

Diplodocus had an extremely long tail, composed of about 80 caudal vertebrae,[14] which is almost double the number some of the earlier sauropods had in their tails (such as Shunosaurus with 43), and far more than contemporaneous macronarians had (such as Camarasaurus with 53).

[16] The tail may have served as a counterbalance for the neck. The middle part of the tail had 'double beams' (oddly-shaped bones on the underside, which gave Diplodocus its name). They may have provided support for the vertebrae, or perhaps prevented the blood vessels from being crushed if the animal's heavy tail pressed against the ground. These 'double beams' are also seen in some related dinosaurs.

Like other sauropods, the manus (front "feet") of Diplodocus were highly modified, with the finger and hand bones arranged into a vertical column, horseshoe-shaped in cross section. A horseshoe is a U-shaped item made of metal or of modern synthetic materials nailed or glued to the Hooves of Horses and some other Draught Diplodocus lacked claws on all but one digit of the front limb, and this claw was unusually large relative to other sauropods, flattened from side to side, and detached from the bones of the hand. The function of this unusually specialized claw is unknown. [17]

Several species of Diplodocus were described between 1878 and 1924. The first skeleton was found at Como Bluff, Wyoming by Benjamin Mudge and Samuel Wendell Williston in 1878, and was named Diplodocus longus ('long double-beam'), by paleontologist Othniel Charles Marsh in 1878. In Biology, the skeleton is a strong and often a rigid framework that supports the body of an animal holding it upright and giving it shape and strength (Also skeletal Como Bluff is a long ridge extending east-west located between the towns of Rock River and Medicine Bow, Wyoming.

The two Morrison Formation sauropod genera Diplodocus and Barosaurus had very similar limb bones. In the past, many isolated limb bones were automatically attributed to Diplodocus but may, in fact, have belonged to Barosaurus. [19]

Paleobiology

Due to a wealth of skeletal remains, Diplodocus is one of the best-studied dinosaurs. Many aspects of its lifestyle have been subjects of various theories over the years.

Habitat

Marsh and then Hatcher[26] assumed the animal was aquatic, because of the position of its nasal openings at the apex of the cranium. John Bell Hatcher ( October 11, 1861 &ndash July 3, 1904) was an American Paleontologist and fossil hunter best known Similar aquatic behavior was commonly depicted for other large sauropods such as Brachiosaurus and Apatosaurus. Brachiosaurus (ˌbrækiəˈsɔrəs meaning "arm lizard" from the Greek brachion /βραχιων meaning "arm" and sauros The idea of an aquatic existence was later debunked, as the water pressure on the chest wall of Diplodocus was proven to have been too great for the animal to have breathed. Since the 1970s, general consensus has the sauropods as firmly terrestrial animals, browsing on trees. However, a more recent theory suggests a likely riparian habitat for Diplodocus. "Riparian" redirects here For the legal doctrine see " Riparian water rights.

Posture

The depiction of Diplodocus posture has changed considerably over the years. For instance, a classic 1910 reconstruction by Oliver P. Hay depicts two Diplodocus with splayed lizard-like limbs on the banks of a river. Hay argued that Diplodocus had a sprawling, lizard-like gait with widely-splayed legs,[28] and was supported by Gustav Tornier. However, this hypothesis was put to rest by W. J. Holland, who demonstrated that a sprawling Diplodocus would have needed a trench to pull its belly through. [29]

A classic depiction of Diplodocus by Mary Woodward (1905), with neck high up in the air and tail on the ground, a posture now generally believed to be incorrect

Later, diplodocids were often portrayed with their necks held high up in the air, allowing them to graze from tall trees. Diplodocids, or members of the family Diplodocidae ("double beams" are a group of Sauropod Dinosaurs The family includes some of the longest More recently, scientists have argued that the heart would have had trouble sustaining sufficient blood pressure to oxygenate the brain. Furthermore, more recent studies have shown that the structure of the neck vertebrae would not have permitted the neck to bend far upwards. [30][31]

As with the related genus Barosaurus, the very long neck of Diplodocus is the source of much controversy among scientists. A 1992 Columbia University study of Diplodocid neck structure indicated that the longest necks would have required a 1. Columbia University is a private University in the United States and a member of the Ivy League. 6 ton heart — a tenth of the animal's body weight. The study proposed that animals like these would have had rudimentary auxiliary 'hearts' in their necks, whose only purpose was to pump blood up to the next 'heart'. [4]

While the long neck has traditionally been interpreted as a feeding adaptation, a recent study[32] suggests that the oversized neck of Diplodocus and its relatives may have been primarily a sexual display, with any other feeding benefits coming second.

Diet

Diplodocus has highly unusual teeth compared to other sauropods. The crowns are long and slender, elliptical in cross-section, while the apex forms a blunt triangular point. [33] The most prominent wear facet is on the apex, though unlike all other wear patterns observed within sauropods, Diplodocus wear patterns are on the labial (cheek) side of both the upper and lower teeth. [33] What this means is Diplodocus and other diplodocids had a radically different feeding mechanism than other sauropods. Unilateral branch-stripping is the most likely feeding behaviour of Diplodocus,[34][35][36] as it explains the unusual wear patterns of the teeth (coming from tooth-food contact). In unilateral branch stripping, one tooth row would have been used to strip foliage from the stem, while the other would act as a guide and stabiliser. With the elongated preorbital (in-front of the eyes) region of the skull, longer portions of stems could be stripped in a single action. [33] Also the palinal (backwards) motion of the lower jaws could have contributed two significant roles to feeding behaviour: 1) an increased gape, and 2) allowed fine adjustments of the relative positions of the tooth rows, creating a smooth stripping action. [33]

Model Diplodocus standing on its hind legs in Bałtów, Poland.

With a laterally and dorsoventrally flexible neck, and the possibility of using its tail and rearing up on its hind limbs (tripodal ability), Diplodocus would have had the ability to browse at many levels (low, medium, and high), up to approximately 10 metres (33 ft) from the ground. [37] The neck's range of movement would have also allowed the head to graze below the level of the body, leading some scientists to speculate on whether Diplodocus grazed on submerged water plants, from riverbanks. This concept of the feeding posture is supported by the relative lengths of front and hind limbs. Furthermore, its peglike teeth may have been used for eating soft water plants. [30]

a) skull, b) classic rendering of the head with nostrils on top, c) Bakker's theory of a trunk, d) modern depiction with nostrils low on the snout and a possible resonating chamber

The head of Diplodocus has been widely depicted with the nostrils on top due to the position of the nasal openings at the apex of the skull. There has been speculation over whether such a configuration meant that Diplodocus may have had a trunk. [38] A recent study[39] surmised there was no paleoneuroanatomical evidence for a trunk. It noted that the facial nerve in an animal with a trunk, such as an elephant, is large as it innervates the trunk. The facial nerve is the seventh (VII of twelve paired Cranial nerves. The evidence suggests that the facial nerve is very small in Diplodocus. Studies by Lawrence Witmer (2001) indicated that, while the nasal openings were high on the head, the actual, fleshy nostrils were situated much lower down on the snout. [40]

Recent discoveries have suggested that Diplodocus and other diplodocids may have had narrow, pointed keratinous spines lining their back, much like those on an iguana. Keratins are a family of fibrous structural proteins; tough and insoluble they form the hard but nonmineralized structures found in Reptiles Birds Iguana is a Genus of Lizard native to tropical areas of Central and South America and the Caribbean first described by Austrian [41][42] This radically different look has been incorporated into recent reconstructions, notably Walking with Dinosaurs. Walking with Dinosaurs was a six-part Television series produced by the BBC, narrated by Kenneth Branagh, and first aired in the UK It is unknown exactly how many diplodocids had this trait, and whether it was present in other sauropods.

Reproduction and growth

While there is no evidence for Diplodocus nesting habits, other sauropods such as the titanosaurian Saltasaurus have been associated with nesting sites. Sauropoda (sɔˈrɒpədə or the sauropods (/ˈsɔroʊpɒd/ are a suborder or infraorder of the Saurischian ("lizard-hipped" Titanosaurs (members of the groups Titanosauria and/or Titanosauroidea) were a diverse group of sauropod Dinosaurs which included Saltasaurus Saltasaurus (which means "lizard from Salta " is a Genus of Sauropod Dinosaur of the Late Cretaceous [43][44] The titanosaurian nesting sites indicate that may have laid their eggs communally over a large area in many shallow pits, each covered with vegetation. It is possible that Diplodocus may have done the same. The documentary Walking with Dinosaurs portrayed a mother Diplodocus using an ovipositor to lay eggs, but it was pure speculation on the part of the documentary. Walking with Dinosaurs was a six-part Television series produced by the BBC, narrated by Kenneth Branagh, and first aired in the UK The ovipositor is an organ used by some of the Animals for Oviposition, i

Following a number of bone histology studies, Diplodocus, along with other sauropods, grew at a very fast rate, reaching sexual maturity at just over a decade, though continuing to grow throughout their lives. Bones are rigid organs that form part of the Endoskeleton of Vertebrates They function to move support and protect the various organs of the body produce Histology (from the Greek = 'tissue' is the study of the microscopic anatomy of cells and tissues of Plants and Sexual maturity is the age or stage when an Organism can reproduce.
