Hexinlusaurus was a small basal ornithischian dinosaur that lived during the Middle Jurassic period, approximately 171 million years ago. This diminutive plant-eater inhabited what is now the Sichuan Province of China, where its fossils were discovered in the famous Lower Shaximiao Formation. As one of the earliest members of the ornithischian group, Hexinlusaurus provides valuable insights into the evolution of bird-hipped dinosaurs.
This small dinosaur measured roughly 1.2 metres in length and stood about half a metre tall at the hip, weighing approximately 8 kilograms. Hexinlusaurus was a bipedal creature, walking on its hind legs whilst using its shorter front limbs for other activities such as gathering food. Its build suggests it was an agile animal, well-suited to navigating the dense forests and open woodlands of Middle Jurassic China.
As a herbivore, Hexinlusaurus fed on the abundant plant life of its time, including ferns, cycads, and conifers. Its teeth were adapted for processing tough plant material, and like other ornithischians, it possessed a beak-like structure at the front of its mouth for cropping vegetation. The dinosaur's digestive system would have been specially adapted to break down the fibrous plant matter that formed its diet.
Hexinlusaurus represents an important link in understanding how the diverse group of ornithischian dinosaurs evolved and spread across the ancient world during the Jurassic period.
What made Hexinlusaurus distinctive?
Hexinlusaurus was characterised by its small, lightweight build and bipedal stance. It possessed multiple rows of small teeth, which gave it the species name 'multidens', meaning 'many teeth'. The dinosaur had relatively long hind limbs compared to its body size, suggesting it was built for speed and agility.
Behaviour
Hexinlusaurus likely lived in small groups, foraging together for plant material in the forests and woodlands of Middle Jurassic China. Its small size and agile build suggest it relied on speed to escape from predators rather than defensive armour or weapons. The dinosaur probably spent much of its day actively searching for suitable vegetation to meet its dietary needs.
Discovery
Hexinlusaurus was first described by He Xinlu and Cai Kaiji in 2005. The original fossils were discovered at Lower Shaximiao Formation, Sichuan Province, China.
Hexinlusaurus FAQ
What did Hexinlusaurus eat?
Hexinlusaurus was a herbivore that fed on the plant life available during the
Middle Jurassic period. Its diet would have consisted of ferns, cycads, conifers, and other vegetation. Its multiple rows of small teeth were specially adapted for processing tough plant material, whilst its beak-like front helped it crop vegetation efficiently.
How big was Hexinlusaurus?
Hexinlusaurus was quite small, measuring approximately 1.2 metres in total length and standing about 0.5 metres tall at the hip. It weighed roughly 8 kilograms, making it one of the smaller dinosaurs known from the
Middle Jurassic period. Its compact size made it an agile and quick-moving plant-eater.
When did Hexinlusaurus live?
Hexinlusaurus lived during the
Middle Jurassic period, approximately 171 million years ago. This was a time when dinosaurs were becoming increasingly diverse, and the climate was warm and humid, supporting lush vegetation that provided ample food for herbivorous dinosaurs like Hexinlusaurus.
Where was Hexinlusaurus found?
Hexinlusaurus fossils were discovered in China, specifically in the Lower Shaximiao Formation of Sichuan Province. This fossil-rich formation has yielded many important dinosaur discoveries and provides a window into
Middle Jurassic ecosystems in what is now eastern Asia.
How do you pronounce Hexinlusaurus?
Hexinlusaurus is pronounced 'HEX-in-loo-SORE-us'. The name honours He Xinlu, a prominent Chinese palaeontologist who has made significant contributions to dinosaur research, combined with the Greek word 'saurus' meaning lizard.
What does Hexinlusaurus mean?
Hexinlusaurus means 'Hexinlu Lizard', named after He Xinlu, one of China's most accomplished dinosaur hunters. The species name 'multidens' means 'many teeth', referring to the creature's multiple rows of small teeth that were adapted for processing plant material.
How fast could Hexinlusaurus run?
The exact running speed of Hexinlusaurus is unknown, but its body structure suggests it was built for agility and quick movement. Its relatively long hind limbs and lightweight build indicate it could probably run quite fast for its size, which would have been essential for escaping predators.
What type of dinosaur was Hexinlusaurus?
Hexinlusaurus was a basal ornithischian dinosaur, representing one of the earliest members of the 'bird-hipped' dinosaur group. It was a small, bipedal herbivore that helps scientists understand the early evolution and diversity of ornithischian dinosaurs during the
Middle Jurassic period.
Was Hexinlusaurus related to birds?
Although Hexinlusaurus was an ornithischian or 'bird-hipped' dinosaur, it was not directly related to modern birds. Birds actually evolved from theropod dinosaurs, which belong to the saurischian or 'lizard-hipped' group. The term 'bird-hipped' refers only to the similar pelvic structure, not an evolutionary relationship to birds.
How many Hexinlusaurus fossils have been found?
Hexinlusaurus is known from limited fossil material, which is typical for many smaller dinosaur species as their delicate bones are less likely to be preserved. The fossils that have been found provide enough information to understand its basic anatomy and lifestyle, but more discoveries would help scientists learn additional details about this early ornithischian dinosaur.
