Taohelong was an armoured ankylosaur that roamed the landscapes of what is now north-central China during the Early Cretaceous period, approximately 126 million years ago. This heavily built herbivore belonged to a group of dinosaurs known for their impressive defensive armour, and Taohelong was no exception to this rule.
Like other ankylosaurs, Taohelong was a quadrupedal plant-eater with a low-slung body perfectly adapted for browsing on ferns, cycads, and early flowering plants that grew close to the ground. Its most distinctive feature was its extensive body armour, including a remarkable 'sacral shield' - a carpet of bony plates called osteoderms that covered its hip region like natural chainmail.
The fossil remains of Taohelong, discovered in the Hekou Group rocks of the Lanzhou-Minhe Basin, include tail vertebrae, ribs, a left hip bone, and crucially, several pieces of its protective armour. These fossils provide valuable insights into the diversity of armoured dinosaurs that lived in Asia during the Early Cretaceous.
As a member of the nodosaurid family within the ankylosaur group, Taohelong lacked the distinctive tail club found in some of its relatives, instead relying on its heavy armour plating and possibly shoulder spikes for protection against predators that shared its ancient Chinese habitat.
What made Taohelong distinctive?
Taohelong possessed a distinctive 'sacral shield' made up of numerous small bony plates that formed a protective carpet over its hip region. Its body was covered in osteoderms - bony armour plates embedded in the skin that provided excellent protection from predators.
Behaviour
As a herbivorous ankylosaur, Taohelong would have spent much of its time browsing on low-growing vegetation, using its beak-like mouth to strip leaves and shoots. When threatened, it likely crouched down to protect its soft underbelly, presenting only its heavily armoured back and sides to potential predators.
Discovery
Taohelong was first described by Yang Jing-Tao, You Hai-Lu, Li Da-Qing, and Kong De-Lai in 2013. The original fossils were discovered at Hekou Group, Lanzhou-Minhe Basin, Gansu Province, China.
Taohelong FAQ
What did Taohelong eat?
Taohelong was a herbivore that fed on the plants available in
Early Cretaceous China, including ferns, cycads, and early flowering plants. It would have used its beak-like mouth to strip leaves and shoots from low-growing vegetation, processing tough plant material with its grinding teeth.
How big was Taohelong?
Taohelong was a medium-sized ankylosaur, measuring approximately 4 metres in length and standing about 1.2 metres tall at the hip. It weighed an estimated 1.5 tonnes, making it a substantially built but not gigantic armoured dinosaur.
When did Taohelong live?
Taohelong lived during the
Early Cretaceous period, approximately 126 million years ago. This was a time when flowering plants were beginning to diversify and many new types of dinosaurs were evolving across the world.
Where was Taohelong found?
Taohelong fossils were discovered in the Hekou Group rock formations in the Lanzhou-Minhe Basin of Gansu Province, north-central China. The remains are housed in the Gansu Dinosaur Museum.
How do you pronounce Taohelong?
Taohelong is pronounced 'TAO-heh-long', with the emphasis on the first syllable. The name combines Chinese elements meaning 'river Tao' and 'dragon'.
What does Taohelong mean?
Taohelong means 'dragon of the river Tao', referring to both the Tao River region where it was discovered and the Chinese cultural tradition of dragons. The name reflects its discovery location in north-central China.
How fast could Taohelong run?
The speed of Taohelong is unknown, but like other heavily armoured ankylosaurs, it was probably not a fast runner. Its body was built for protection rather than speed, and it likely relied on its armour rather than fleeing when threatened.
What type of dinosaur was Taohelong?
Taohelong was an ankylosaur, specifically a member of the nodosauridae family. Ankylosaurs were heavily armoured, herbivorous dinosaurs known for their defensive adaptations including bony plates and spikes covering their bodies.
Was Taohelong related to birds?
Taohelong was not closely related to birds. As an ankylosaur, it belonged to the ornithischian group of dinosaurs, while birds evolved from theropod dinosaurs in the saurischian group. However, both groups shared common dinosaurian ancestors.
How many Taohelong fossils have been found?
Taohelong is known from a single fossil specimen (GSDM 00021) that includes a tail vertebra, ribs, a left hip bone, and several pieces of bony armour. While limited, these remains were sufficient to identify it as a new species of nodosaurid ankylosaur.
