Tianyulong is a fascinating extinct dinosaur that lived during the Late Jurassic period, around 158.5 million years ago. It belonged to a group of dinosaurs called heterodontosaurids, which were small, herbivorous creatures with some unique features.
The only known species of Tianyulong is called T. confuciusi. Its remains were found in Jianchang County, located in Western Liaoning Province, China.
Fossils of Tianyulong were initially thought to be from the Early Cretaceous period. However, later studies revealed that they were older and really dated back to the Late Jurassic time.
When scientists examined the fossil skeleton of Tianyulong, they found several interesting parts. This skeleton included a partial skull, parts of the backbone, some of the leg bones, and even evidence of long, hair-like structures on its back, tail, and neck. It is believed that Tianyulong was about 70 centimeters long, which is similar in size to related dinosaurs from South Africa.
One of the most exciting aspects of Tianyulong is the long filaments on its body. These structures resemble early forms of feathers, suggesting that early dinosaurs and their ancestors may have had similar coverings.
Tianyulong was classified as a heterodontosaurid, a group known for their slender bodies, long tails, and tusk-like teeth. It is believed these dinosaurs could be plant-eaters, or possibly even eat other small creatures.
In summary, Tianyulong helps us learn more about the characteristics of early dinosaurs and offers clues about the evolution of feathers.
