Dinosaurs evolved around the Triassic period dating back to 243-233 million years ago and went extinct about 66 million years ago. The age of dinosaurs, or the Mesozoic Era meaning the middle life, includes Triassic, Jurassic, and Cretaceous periods. While dinosaurs did not have major threats, an asteroid hit that blocked the sun and caused a rapid decrease in the temperature of the Earth is speculated to have catalyzed the extinction of dinosaurs as dinosaurs could not survive the climate change.
Dinosaurs were named by Richard Owen and the name has a Greek origin meaning 'terrible lizard'. With the classification of over 700 species under 300 genera of dinosaurs under the clade Dinosauria, they are considered ancestors to modern birds and reptiles. One genera classified under the clade Dinosauria was the Analong discovered by Xin-Xin Ren, Toru Sekiya, Tao Wang, Zhi-Wen Yang, and Hai-Lu. The genus of the Mamenchisaurid Sauropod inhabited China during the middle Jurassic period around 170-168 million years ago. Although the holotype of the dinosaur found in 1995 was described as the specimen of Chuanjiesaurus, it was assigned a new genus, Analong, in 2020 specifying differences between the Analong and the Chuanjiesaurus. The generic name refers to Ana, a village in the Yunnan province in China where the holotype specimen of fossils was found. The binomial name of the genus means 'Ana dragon', while the name of the type species means 'Ana dragon from Chuanjie'. It belongs to the clade Saurischia and the family Mamenchisauridae while the only species of the genus documented was the Analong chuanjieensis.
The generic name, Analong, is pronounced as 'an-a-long'. While the specimen of Chuanjiesaurus was assigned the contemporary genus, Chuanjiesaurus, the genus was named Analong, meaning 'Ana dragon', in 2020 by Xin-Xin Ren, Toru Sekiya, Tao Wang, Zhi-Wen Yang, and Hai-Lu You. The type species under the genus was Analong chuanjieensis meaning 'Ana dragon from Chuanjie'.
The classification of Analong is as a genus under the clade Dinosauria and the Saurischia among other 300 genera such as Mamenchisaurid Sauropod dinosaurs. The dinosaur was unearthed from the Chuanjie formation in China in 1995, but the referred specimen of the Chaunjiesaurus was described as Analong in 2020 by Xin-Xin Ren, Toru Sekiya, Tao Wang, Zhi-Wen Yang, and Hai-Lu. Thus, it was speculated to be closely related to the Chaunjiesaurus.
An Analong fossil was uncovered from the Chuanjie formation in China in 1997 and it is thought that the Analong lived during the middle Jurassic period around 170-168 million years ago.
The Analong, a Mamenchisaurid Sauropod from China, dates back to the middle Jurassic period but does not have an estimated period of extinction. While dinosaurs faced extinction 66 million years ago, there are several speculations justifying what caused the age of dinosaurs to end. Climate change, habitat loss, predators, or natural calamities are considered primary causes catalyzing the extinction of animals.
The specimen of Chuanjiesaurus was collected from the Chuanjie formation, Lufeng County in the Yunnan province, China and was later described to be fossils of an Analong in 2020. Fossil remains reveal that the Analong inhabited China.
Not much can be deciphered from fossil remains of these animals. The habitat of the dinosaur was assumed to be wet-dry woodlands, forests, semi-arid deserts, and areas with plentiful vegetation around the world. Although the Analong was known to reside around China, the favorable habitat of the dinosaur remains questionable.
This species of animals either led a solitary life or lived in pairs, trios, or groups. Often a dinosaur was known to live in groups but in the case of an Analong, the behavior of the dinosaur is poorly studied.
Although a dinosaur was reported to live around 70-80 years, Mamenchisaurid Sauropods of China do not have an estimated life span.
Since the Analong chuanjieensis dinosaur from the genus Analong is poorly studied, the reproductive behavior of the dinosaur remains unknown. On the other hand, a dinosaur, in general, was an oviparous animal that laid eggs to reproduce. It laid amniotic eggs in a nest. The nest was speculated to be a cup, dome, plate, bed, scrape, mound, or burrow depending on the situation. While the female was known to lay eggs, she also grew a bone rich in calcium when laying eggs. The medullary bone was used to make eggshells. The bone also helps paleontologists to decipher the sex of the dinosaur by studying these fossils. Although the brooding position may differ, the female was reported to use an insulating layer of feathers to keep eggs warm until they hatched. Sauropods were considered precocial or superprecocial animals as young ones were relatively mature at birth.
The holotype of the Analong was formerly referred to as the specimen of Chuanjiesaurus. Fossils were found in 1995 from the Chuanjie Formation, China but were described and named the Analong in 2020 by Xin-Xin Ren, Toru Sekiya, Tao Wang, Zhi-Wen, and Hai-Lu. The genus Analong with the type species Analong chuanjieensis is poorly studied. The study of fossils failed to provide a description of the Analong chuanjieensis found during the early and middle Jurassic epochs. While it was closely related to the Chuanjiesaurus, it was a quadruped with a long neck. Also, it had a scaly body.
Fossils of the Analong from the family Mamenchisauridae living during the early and middle Jurassic epochs were uncovered from the Chuanjie formation in China in 1995 and were named Analong ('Ana dragon') by Xin-Xin Ren, Toru Sekiya, Tao Wang, Zhi-Wen, and Hai-Lu in 2020. Yet, it is poorly studied and the number of bones remains a mystery.
Prehistoric animals from the clade Dinosauria were speculated to communicate vocally and visually. Also, they communicated using various gestures and movements. They used various techniques to communicate like hissing, clapping jaws together, hooting, making cracking sounds, or other gestures and movements. The behavior of the Analong chuanjieensis from the family Mamenchisauridae living during the middle Jurassic period is yet not known.
Around the world, the Argentinosaurus was known to have a length of around 130 ft (39.6 m), while the Anchiornis huxleyi was the smallest with a length ranging up to 1.1 ft (34 cm). The Analong size is unrecorded so far. The species from the family Mamenchisauridae under the clade Saurischia was described and named in 2020 but is poorly studied. As it was closely related to the Chuanjiesaurus, the American paleontologist Thomas Richard Holtz Jr. reported that the Chuanjiesaurus was as long as 82 ft (25 m).
The Analong chuanjieensis from the clade Saurischia and the family Mamenchisauridae is one of the recently uncovered prehistoric animals around the world. The Analong, a Mamenchisaurid, was known to move on its four legs but the speed is not recorded.
While an unnamed Mamenchisaurid was recorded to weigh about 27.6 tons (25,075 kg), the weight of the Analong from the family Mamenchisauridae has not been computed so far.
The female and male Analong do not have sex-specific names.
A baby Analong can be called out as a chick, hatchling, or juvenile.
The Analong was an herbivore member of the family Mamenchisauridae, primarily feeding upon leaves, roots, and fruits of various plants within its range.
Although there is not much speculated about the behavior of the Analong, the Mamenchisaurid Sauropod was not known to have an aggressive temperament.
The Analong is a member of the family Mamenchisauridae. When the specimen was unearthed in 1995, it was assigned the contemporary genus, Chuanjiesaurus. Then it was named under the genus of Analong in 2020. It is a poorly studied prehistoric creature. Thus, several facts about the animal are yet to be unveiled.
Analong means 'Ana dragon' while the binomial name of its only subspecies, Analong chuanjieensis, means 'Ana dragon from Chuanjie'.
While the population of the Mamenchisaurid is not reported, the Analong was known to have only one subspecies, the Analong chuanjieensis.
