Anhuilong was a massive sauropod dinosaur that roamed the lush landscapes of what is now China during the Middle Jurassic period, approximately 175 million years ago. This enormous plant-eater belonged to the mamenchisaurid group, which were characterised by their exceptionally long necks and were among the largest land animals ever to walk the Earth.
Measuring around 18 metres in length and standing about 3.5 metres tall at the hip, Anhuilong would have weighed roughly 12 tonnes. Like other sauropods, it possessed the classic long-necked body plan with four massive, pillar-like legs to support its enormous weight. Its incredibly elongated neck would have allowed it to browse vegetation at heights that other herbivorous dinosaurs simply couldn't reach.
As a herbivore, Anhuilong spent most of its time feeding on the abundant plant life of the Middle Jurassic period, including ferns, conifers, and cycads. It would have used its relatively small head to strip leaves and soft shoots from trees, swallowing them whole without chewing. The plant matter would then be processed in its enormous digestive system, possibly with the aid of gastroliths (stomach stones) to help break down tough plant fibres.
The discovery of Anhuilong has provided valuable insights into the diversity and evolution of mamenchisaurid sauropods in ancient China, adding to our understanding of how these gentle giants adapted to their prehistoric environments.
What made Anhuilong distinctive?
Anhuilong possessed an exceptionally long neck typical of mamenchisaurid sauropods, with elongated cervical vertebrae that would have made up nearly half its total body length. Its skull was relatively small compared to its massive body, and it had robust limb bones designed to support its enormous weight.
Behaviour
Anhuilong likely lived in herds for protection against predators, using its towering height to spot danger across the Middle Jurassic landscape. It would have spent most of its waking hours feeding, requiring vast quantities of vegetation to fuel its massive body and likely migrating seasonally to follow food sources.
Discovery
Anhuilong was first described by Xing Xu and colleagues in 2018. The original fossils were discovered at Hongqin Formation, Anhui Province, China.
Anhuilong FAQ
What did Anhuilong eat?
Anhuilong was a herbivore that fed on the abundant plant life of the
Middle Jurassic period, including ferns, conifers, cycads, and other prehistoric vegetation. It used its long neck to reach high into the tree canopy to browse on leaves and soft shoots that other dinosaurs couldn't access.
How big was Anhuilong?
Anhuilong was approximately 18 metres long and stood about 3.5 metres tall at the hip. It weighed an estimated 12 tonnes, making it one of the larger sauropod dinosaurs, though not the biggest ever discovered.
When did Anhuilong live?
Anhuilong lived during the
Middle Jurassic period, approximately 174.7 million years ago. This was a time when the climate was warm and humid, supporting lush vegetation that could sustain massive herbivorous dinosaurs like Anhuilong.
Where was Anhuilong found?
Anhuilong fossils were discovered in the Hongqin Formation in Anhui Province, eastern China. The genus is actually named after this province, reflecting its importance as the dinosaur's homeland.
How do you pronounce Anhuilong?
Anhuilong is pronounced 'AHN-hway-long', with the first part reflecting the Chinese pronunciation of Anhui Province where it was discovered.
What does Anhuilong mean?
Anhuilong means 'Anhui Dragon', named after Anhui Province in China where its fossils were found. The name follows the common practice of naming dinosaurs after their discovery locations.
How fast could Anhuilong run?
Like most large sauropods, Anhuilong was not built for speed. Its massive size and weight meant it likely moved at a slow, steady pace, probably no faster than a walking human at around 5-8 km/h.
What type of dinosaur was Anhuilong?
Anhuilong was a sauropod dinosaur, specifically a member of the Mamenchisauridae family. Sauropods were the largest land animals ever to exist, characterised by their long necks, long tails, small heads, and four pillar-like legs.
Was Anhuilong related to birds?
As a sauropod, Anhuilong was more distantly related to modern birds than theropod dinosaurs were. However, all dinosaurs, including sauropods like Anhuilong, share a common ancestor with birds, making them part of the broader group that eventually gave rise to our feathered friends.
How many Anhuilong fossils have been found?
Anhuilong is known primarily from its holotype specimen discovered in the Hongqin Formation. As a relatively recently described dinosaur (2018), additional fossil material may yet be discovered that could provide more insights into this impressive sauropod.
