According to a study by Brian Curtis, an archaeologist at the Arizona Museum of Natural History, when the supersorus was alive about 150 million years ago during the Jurassic period, its length exceeded 39 meters and may have reached 42 meters from nose to tail.

The double-breasted supernatural has long been considered one of the tallest dinosaurs, but after scientists adjusting the fossil composition and analyzing the new bones in the long neck, research now shows that the double-breasted supernova could win the world’s tallest title. Dinosaur.

Supersorus is a genus of Diplodocus saropod dinosaur that was first discovered in the late Jurassic rocks of Central Morrison formation in Colorado in 1972, and then in Portugal, 153 million years ago in the fossil record.

Like other tall dinosaurs, the double-branched supersorus is a large, long-necked dinosaur with a whip-like tail.

Brian Curtis, an archaeologist at the Arizona Museum of Natural Sciences, is leading the research. Is expected The direct science is that “this is the tallest dinosaur based on a decent skeleton”, so it is difficult to estimate their length accurately as the remains of other dinosaurs are fragmented.

It took almost 50 years for the new invention

According to To study In 2006 a model called Seismosaurus was unveiled at the Natural History Museum in New Mexico, breaking the record for the smallest size of a double-pillared supersorus.

According to Curtis’ research, when the supersorus was alive about 150 million years ago during the Jurassic period, its length exceeded 39 meters and may have reached 42 meters from nose to tail.

The new discovery has been in the pipeline for nearly 50 years, and the new research, which has not yet been published in the reviewed journal, was presented online at the November 5 annual conference of the Society of Vertebrate Paleontology.

Bone salad

Curtis noted that the first specimen of supersorhes was discovered in 1972 on a bone marrow, which is a mixture of bone and what is known as a “bone salad”. Therefore, it is not immediately clear which bones belong to this dinosaur.

The bones were exhumed by Jim Jensen, who collected and prepared fossils for Brigham Young University in Utah, Colorado. Jensen discovered the 2.4-meter-long scapula – the two joined bones that make up the shoulders of adult dinosaurs and other reptiles.

The quarry also contained extra bones that Jensen thought belonged to two other charopod dinosaurs.

In 1985, Jensen published Study In it, he announces the discovery of 3 new dinosaurs from the same quarry, but unfortunately Jensen is not a trained archaeologist and he made some mistakes in analyzing those specimens.

Over the years, ancient researchers, including Curtis, have discovered that its bones were originally misidentified and that they all actually belonged to a supersorus. The reclassification of the three dinosaurs has created a more complete supernatural, which would be useful to estimate its length.

From the original discovery, other ancient researchers discovered partial skeletons believed to be suprasorus, and by exposing the errors of the past year, Curtis discovered that the long bone was actually deformed by fractures, which led many scientists to believe in the past. Another type of dinosaurs.

He also discovered abnormalities in the bones that caused dystillosarus and other species, and showed that these bones actually belonged to the supernatural.

In addition, excessively large sauropod dinosaur bones were not found nearby. Instead, all the large, double-looking bones were found in one pocket of the socket, with no duplicate (i.e., only the left scapula and right scapula).

The longest recorded dinosaur

The large dinosaur bones are all the same size, so they all belong to a person named Supersorus, Curtis said. When the quarry was excavated, the researchers removed large rocks and fossils and wrapped them in plaster jackets.

After examining some of these bones that had not been examined for years, Curtis found 5 new neck vertebrae, one new posterior vertebra, two new tail vertebrae and one left pubis.

These newly identified bones helped Curtis to get an accurate estimate of the new length of the supersorus, including that its neck was more than 15 meters long and its tail was over 18 meters long.

Furthermore, the size and shape of the newly identified bones support the notion that all massive bones belong to the supernatural rather than to 3 different large dinosaurs.

Supersaurus may be the tallest recorded dinosaur, but it is not the largest. Curtis said the honor could go to the super-heavy titanosaur Argentinosaurus, which weighs more than 90 tons and weighs twice as much as the superpower.
