Over 40 meters! Supersaurus, the longest dinosaur species in history (STUDY)
The gold medal for the world’s tallest dinosaur could go to the Supersaurus of the right name, now that scientists have arranged a fossil mix and analyzed new bones excavated from the dinosaur’s last resting place with a long neck.
Like other extremely tall dinosaurs, the Supersaurus is a diplodocid - a long-necked sauropod whose tail resembled a whip. Supersaurus has always been seen as one of the tallest dinosaurs, but research now shows that "this is the tallest dinosaur based on a good skeleton", as other dinosaur remains are fragmentary and it is challenging to accurately estimate the length of Brian Curtice, a paleontologist at the Arizona Museum of Natural History who is leading the research, told Live Science
When the Supersaurus was alive, about 150 million years ago, during the Jurassic period, it crossed 39 meters and probably even reached 42 meters from the feces to the tail, new Curtice research has revealed. Even its "shortest" dimensions are record; at 128 feet, the dinosaur would have been taller than another contender - Diplodocus, who could reach a length of 108 feet (33 m), according to a 2006 study of a specimen known as the Seismosaurus in the Bulletin of the Museum of Natural History and Science in New Mexico. .
The research, which has not yet been published in a journal reviewed by scientists, was presented online on November 5 at the annual conference of the Vertebrate Paleontology Association.
The new discovery is nearly 50 years in preparation; the first Supersaurus specimen was discovered in 1972 in a bed full of bones, in what was essentially a "bone salad," Curtice said. So it was not immediately clear which bones belonged to the beast.
That bone salad was excavated by dinosaur worker Jim Jensen, who collected and prepared fossils for Brigham Young University in Utah, in the Dry Mesa Dinosaur Career in Colorado. Jensen discovered an 8-foot (2.4 m) scapulocoracoid - two fused bones that make up the shoulder girdle of adult dinosaurs and other reptiles. The 'salad' also contained extra bones that Jensen thought belonged to two other sauropod dinosaurs, whom he later named Ultrasauros and Dystylosaurus.
Lajmet për kockat e kafshëve u bënë tituj. Publiku ngjallte interes që ekzistonte një dinosaur më i madh se Brachiosaurus, që atëherë konsiderohej si dinozauri më i gjatë, sipas blogut Sauropod Vertebra Picture of the Week (SV-POW), i drejtuar nga paleontologët Michael Taylor dhe Mathew Wedel. Një gazetar rastësisht e quajti bishën më të madhe Supersaurus në furinë pas zbulimit të saj.
In 1985, Jensen published a study in the journal Great Basin Naturalist announcing the discovery of three young sauropod dinosaurs in a quarry. However, Jensen was not a trained paleontologist and he made some mistakes with his analysis. Over the years, paleontologists have debated whether Ultrasauros and Dystylosaurus are valuable genera, or whether - as Curtice believes - their bones were misidentified and in fact all belong to a single Supersaurus.
