It was believed throughout the 19th and early 20th centuries that sauropods like Apatosaurus were too massive to support their own weight on dry land.

It was theorized that they lived partly submerged in water, perhaps in swamps. More recent findings do not support this; sauropods are now thought to have been fully terrestrial animals.

A study of the necks of Apatosaurus and Brontosaurus found many differences between them and other diplodocids, and that these variations may have shown that the necks of Apatosaurus and Brontosaurus were used for intraspecific combat.

One suggestion is that they were used for defense, but their shape and size make this unlikely. It was also possible they were for feeding, but the most probable use for the claw was grasping objects such as tree trunks when rearing.

Diplodocids like Apatosaurus are often portrayed with their necks held high up in the air, allowing them to browse on tall trees.

Some studies state diplodocid necks were less flexible than previously believed, because the structure of the neck vertebrae would not have allowed the neck to bend far upwards, and that sauropods like Apatosaurus were adapted to low browsing or ground feeding.

Other studies by Taylor find that all tetrapods appear to hold their necks at the maximum possible vertical extension when in a normal, alert posture; they argue the same would hold true for sauropods barring any unknown, unique characteristics that set the soft tissue anatomy of their necks apart from that of other animals.

Apatosaurus , like Diplodocus , would have held its neck angled upwards with the head pointing downwards in a resting posture. Matthew Cobley et al.

They state the feeding ranges for sauropods like Diplodocus were smaller than previously believed, and the animals may have had to move their whole bodies around to better access areas where they could browse vegetation.

As such, they might have spent more time foraging to meet their minimum energy needs. He found that the neck of Apatosaurus was very flexible.

Given the large body mass and long neck of sauropods like Apatosaurus , physiologists have encountered problems determining how these animals breathed.

Beginning with the assumption that, like crocodilians , Apatosaurus did not have a diaphragm , the dead-space volume the amount of unused air remaining in the mouth, trachea, and air tubes after each breath has been estimated at about 0.

Paladino calculates its tidal volume the amount of air moved in or out during a single breath at 0. On this basis, its respiratory system would likely have been parabronchi , with multiple pulmonary air sacs as in avian lungs , and a flow-through lung.

An avian respiratory system would need a lung volume of about 0. The overall thoracic volume of Apatosaurus has been estimated at 1.

That would allow about 0. Though this plays a role in reducing the weight of the animal, Wedel states they are also likely connected to air sacs, as in birds.

James Spotila et al. Wedel says that an avian system would have allowed it to dump more heat. This was first noted in and again in Long-bone histology enables researchers to estimate the age that a specific individual reached.

The same growth model indicated Apatosaurus sp. Compared with most sauropods, a relatively large amount of juvenile material is known from Apatosaurus.

Multiple specimens in the OMNH are from juveniles of an undetermined species of Apatosaurus ; this material includes partial shoulder and pelvic girdles, some vertebrae, and limb bones.

OMNH juvenile material is from at least two different age groups and based on overlapping bones likely comes from more than three individuals.

The specimens exhibit features that distinguish Apatosaurus from its relatives, and thus likely belong to the genus.

An article published in reported research of the mechanics of Apatosaurus tails by Nathan Myhrvold and paleontologist Philip J.

Myhrvold carried out a computer simulation of the tail, which in diplodocids like Apatosaurus was a very long, tapering structure resembling a bullwhip.

This computer modeling suggested diplodocids were capable of producing a whiplike cracking sound of over decibels , comparable to the volume of a cannon being fired.

A pathology has been identified on the tail of Apatosaurus , caused by a growth defect. Two caudal vertebrae are seamlessly fused along the entire articulating surface of the bone, including the arches of the neural spines.

This defect might have been caused by the lack or inhibition of the substance that forms intervertebral disks or joints.

The Morrison Formation is a sequence of shallow marine and alluvial sediments which, according to radiometric dating , dates from between This formation is interpreted as originating in a locally semiarid environment with distinct wet and dry seasons.

The Morrison Basin, where dinosaurs lived, stretched from New Mexico to Alberta and Saskatchewan; it was formed when the precursors to the Front Range of the Rocky Mountains started pushing up to the west.

The deposits from their east-facing drainage basins were carried by streams and rivers and deposited in swampy lowlands, lakes, river channels, and floodplains.

Apatosaurus was the second most common sauropod in the Morrison Formation ecosystem, after Camarasaurus.

Those of Apatosaurus ajax are known exclusively from the upper Brushy Basin Member , about — mya. Additional Apatosaurus remains are known from similarly aged or slightly younger rocks, but they have not been identified as any particular species, [78] and thus may instead belong to Brontosaurus.

The Morrison Formation records a time when the local environment was dominated by gigantic sauropod dinosaurs. Shells of bivalves and aquatic snails are also common.

The flora of the period has been evidenced in fossils of green algae, fungi, mosses, horsetails , cycads , ginkgoes , and several families of conifers.

Vegetation varied from river-lining forests of tree ferns with fern understory gallery forests , to fern savannas with occasional trees such as the Araucaria -like conifer Brachyphyllum.

The apparently massive neck was, however, filled with an extensive system of weight-saving air sacs. Apatosaurus , like its close relative Supersaurus , is notable for the incredibly tall spines on its vertebrae, which make up more than half the height of the individual bones.

Also unusual among diplodocids is the shape of the tail, which is comparatively thin in breadth and short in height, a profile caused by the vertebral spines decreasing in height rapidly the farther they are from the hips.

Apatosaurus also had very long ribs compared to most other diplodocids, giving it an unusually deep chest.

The limb bones were also very robust. An article that appeared in the November issue of Discover Magazine reported research into the mechanics of Apatosaurus tails by Nathan Myhrvold, a computer scientist from Microsoft.

Dino-Lite: This creature's neck was relatively light because its vertebrae were hollow. Otherwise, its neck would have been too heavy to lift.

Whipped: The long and muscular tail helped protect against predators. It moved so fast that when it thrashed about, it would have produced a loud crack and a crushing sting like a giant bullwhip.

Passenger Pigeon. A microscopic study of Apatosaurus bones concluded that the animals grew rapidly when young and reached near-adult sizes in about 10 years.

The skull was small in comparison with the size of the animal. The jaws were lined with spatulate teeth, which resembled chisels, suited to an herbivorous diet.

Like other sauropods, the vertebrae of the neck were deeply bifurcated; that is, they carried paired spines, creating a wide and deep profile for the neck.

The cladogram below is the result of an analysis by Tschopp, Mateus, and Benson The authors analyzed most diplodocid type specimens separately to deduce which specimen belonged to which species and genus.

YPM " Atlantosaurus " immanis type. AMNH Amphicoelias altus type. Apatosaurus is a member of the family Diplodocidae , a clade of gigantic sauropod dinosaurs.

The family includes some of the longest creatures ever to walk the earth, including Diplodocus , Supersaurus , and Barosaurus.

Apatosaurus is sometimes classified in the subfamily Apatosaurinae , which may also include Suuwassea , Supersaurus , and Brontosaurus.

He classified this group within Sauropoda, a group he erected in the same study. In Elmer S. Riggs said the name Sauropoda would be a junior synonym of earlier names; he grouped Apatosaurus within Opisthocoelia.
