Diplodocus, depicted with spines limited to the mid-line of the back. Diplodocids were generally large animals, even by sauropod standards. Thanks to their long necks and tails, diplodocids were among the longest sauropods, with some species such as Supersaurus vivianae and Diplodocus hallorum estimated to have reached lengths of 30 meters (100 ft) or more.

Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like Supersaurus, Diplodocus, Apatosaurus, and Amphicoelias. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids ) are the only known sauropods to have re-evolved a short ...
Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The variation in dimensions and weights across birds is one of the fundamental sources of diversity among birds, and even Within species, dimensions may vary across populations within species , between the sexes and depending on age and ...
McCulloch says people can keep cats indoors, turn off lights at night, and put decal stickers or paint patterns on windows to help keep birds safe. Markings should be close together – about two ...
With a neck that is 15 metres long, Mamenchisaurus sinocanadorum might be a record-holder, researchers said. Scientists identify dinosaur with the longest neck ever seen in an animal Skip to main ...
Brontosaurus was a large, long-necked, quadrupedal animal with a long, whip-like tail, and forelimbs that were slightly shorter than its hindlimbs. The largest species, B. excelsus , measured up to 21–22 m (69–72 ft) long from head to tail and weighed up to 15–17 t (17–19 short tons); other species were smaller, measuring 19 m (62 ft ...
Some, like the diplodocids, possessed tremendously long tails, which they may have been able to crack like a whip as a signal or to deter or injure predators, [17] or to make sonic booms. [ 18 ] [ 19 ] Supersaurus , at 33 to 34 metres (108 to 112 ft) long, [ 20 ] was the longest sauropod known from reasonably complete remains, but others, like ...
