On the basis of fossils as the shown one to the right, probably of a Diplodocidae sauropod, we know that these animals presented scales as of the crocodiles.
These scales were of diverse sizes, being that the minors would be located in the regions of the body where movements would occur, as in the joints of the legs.
However, a study of the paleontologist and paleorestorer Stephen Czerkas with a fossil of a Diplodocidae found in Wyoming demonstrated that they presented, in the dorsal part of the tail, a row of thorns.

 diplodocoidea   (Site not responding. Last check: 2007-10-25)
Diplodocoidea is composed of three families: Rebbachisauridae, Dicraeosauridae, and Diplodocidae.
Rebbachisaurids are not yet particularly well known, at the moment being an EK-LK boundary South America-Africa group (possibly into the later LK, depending on what you make of the "Antarctosaurus" jaw) with interesting feeding characteristics.
Diplodocidae provides the stereotype for what most people think of dinosaurs in general and sauropods in particular: long neck, small head, long tail, hips much higher than the shoulders, and a plump-looking body.

 Apatosaurus --  Britannica Student Encyclopedia   (Site not responding. Last check: 2007-10-25)
Apatosaurus is classified as a member of the family Diplodocidae, which contains dinosaurs with exceptionally long necks and tails.
The Diplodocidae belong to the order Saurischia (the lizard-hipped dinosaurs), which...
The skeletal structure of Allosaurus indicates that it was a biped, meaning that it walked on two legs.

 Untitled Document   (Site not responding. Last check: 2007-10-25)
Absence of an ossified calcaneum has been suggested as a synapomorphy of Diplodocidae and used to construct sauropod phylogenetic hypotheses.
Ossified calcanea may have helped to stabilize the pes during locomotion and assisted in the proper alignment and insertion of lateral plantar musculature.
The unusual morphology and unreliable preservation of the sauropod calcaneum suggest that its presence or absence should not be used as a character state, nor should the absence of the calcaneum be used as a synapomorphy of Diplodocidae.

 Diplodocus - Wikipedia, the free encyclopedia
The skull was very small compared to the huge size of the animal, which could reach up to 27 m, although some suggest that the Diplodocus could reach a full length of 45 metres.
Instead of the way Diplodocidae were formerly portrayed, with their necks high up in the air, it is now believed by some that the animal could only keep its head very low to the ground (for grazing), and that the very long tail served as a counterbalance for the long neck.
Others think the animal could stand on its hind legs.

The manus is known only from drawings as original material has been lost; foot bones, except the astragalus, are unknown.
Ferganasaurus forms an unresolved polytomy with neosauropods Jobaria, Diplodocoidea (Nemegtosauridae, Rebbachisauridae, Diplodocidae, and Dicraeosauridae), and Macronaria (Camarasaurus, Haplocanthosaurus and Titanosauriformes).
The neosauropod characters of Ferganasaurus include five coossified sacral vertebra, metacarpal proximal ends subtriangular, composite proximal articular surface of metacarpus U-shaped, tibia with subcircular proximal end, astragalar ascending process extends to the posterior margin of the astragalus, and astragalus wedge-shaped in anterior view.

 Lec 10 - SAUROPODOMORPHA
Sauropods are mainly distinguished by features of the skull, but other features are also distinctive (such as the shape and number of vertebrae).
Slender, peg-like teeth are restricted to the front part of the mouth.
The two most well known genera of the diplodocidae are Diplodocus and Apatosaurus ("Brontosaurus").

 What groups of dinosaurs existed?
The consensus is that they were herbivorous, but some argue for an omnivorous or carnivorous diet.
The two main groups within the sauropods are the Diplodocidae and Macronaria; in addition to these groups are numerous genera which don't fall into either camp, among them Cetiosaurus, the first sauropod to be discovered, and Mamenchisaurus, the dinosaur with the proportionally longest neck.
Apart from some of the larger Diplodocidae, all the largest (in the senses of longest and heaviest) dinosaurs fall into the Macronaria.

 Ivars Peterson's MathTrek -Whips and Dinosaur Tails
Many feature a thin cord or string, called a popper (or cracker), at the tip.
Sauropod dinosaurs of the family Diplodocidae have enormous tails that gradually narrow to thin, delicate tips.
Since the late 19th century, when the fossil remains of the Apatosaurus (formerly known as Brontosaurus) and other family members were first uncovered, observers have often likened the tails to whips and have speculated about what purpose those tails might have served.

 Biogeographic origin of Diplodocidae   (Site not responding. Last check: 2007-10-25)
In Europe, only Cetiosauriscus is known in England and Switzerland but, in other hand, is the earliest known diplodocid (Callovian to ?Tithonian).
Therefore this could suggest that the origin of Diplodocidae was in Europe but soon spread through North America (where had the higher genera diversification) and East Africa.
Anyone have more data on the biogeographic origin of Diplodocidae?

Argentinosaurus, recently discovered in Argentina, will probably will turn out to be the largest dinosaur yet discovered, larger than Ultrasauros or Seismosaurus.
although Seismosaurus will likely continue to hold the record for total length due to its extremely long tail, characteristic of Diplodocidae.
The cross section of one vertebra found of Argentinosaurus measures over five and one half feet in height.
