Fun Sinornithosaurus Facts For Kids
Gallery
Our natural history of about a million years ago talks about dinosaurs of all shapes and sizes. During the early cretaceous time, there is this bird-like dinosaur that caught the eyes of paleontologists.
This dinosaur is known as the Sinornithosaurus, also known as the Chinese bird lizard. They have this very famous name because of their ability to hunt down smaller reptiles and birds.
They are a class of venomous dinosaurs and are extremely dangerous. The discovery of the Sinornithosaurus is also very surprising as they are the first dinosaurs with feathers.
A lot of evidence supports the their habit of leaping and it also assumed that they lived and hunted in groups. Their poison is their strong point when it comes to hunting animals or any kind of snake.
They are considered the earliest discovered feathered species. Before the Sinornithosaurus, feather features in a dinosaur was very rare in paleontology. Paleontologists such as Gong discovered that they are also closely related to other non-avian dinosaurs such as the Microraptor.
The Museum of China is responsible for uncovering several truths about the Sinornithosaurus. Their complete fossil and feather impressions are gathered from China's Liaoning province. Xing and Wang share a close relationship with the Sinornithosaurus fossil and a lot is learned about this raptor through this fossil.

Sinornithosaurus Interesting Facts
How do you pronounce 'Sinornithosaurus'?
The Sinornithosaurus venom is the primitive characteristic of these dinosaurs. This dinosaur bite can indeed be deadly due to their poison, although overall the Sinornithosaurus size is not that huge. You can pronounce the name of this dinosaur like 'SINE-or-nith-oh-SAWR-us'.
What type of dinosaur was a Sinornithosaurus?
These Chinese bird lizards have a soft cavity beneath their jaw which is where the venom glands are. Scientists such as Gong and Xing believe that these small features, which are very different from ordinary dinosaurs, may be pointing towards the fact that this dinosaur hunted small prey.
The Yixian formation believes that the Sinornithosaurus is a small dromaeosaurid. At first, they were considered to be theropods due to similarities in the teeth and other such features.
In which geological period did the Sinornithosaurus roam the earth?
Sinornithosaurus millenii lived in Asia, especially in China. They lived around 130 million years ago during the early Cretaceous period.
When did the Sinornithosaurus become extinct?
It's known that this feathered dinosaur with fangs lived during the early Cretaceous period and there is evidence to support this time period. All early dinosaurs faced extinction because of asteroid collisions, and this is the same reason for Sinornithosaurus dinosaurs.
Evidence to support their extinction due to volcanic eruptions and unfavorable climates on earth can be found in the Museum of China.
Where did a Sinornithosaurus live?
Considering this dinosaur is from the early Cretaceous period, this feathered dinosaur lived in several areas of Asia. There were other related non-avian dinosaurs who shared the same habitat with them and hunted birds. China is known as the main habitat for this venomous dinosaur because a lot of their fossils have been collected from there.
What was a Sinornithosaurus's habitat?
The main habitat of these dinosaurs can be regions that had fewer numbers of large dinosaurs because it would be easy to hunt down the tiny Sinornithosaurs. Around 1 million years ago, the size of the dinosaur mattered a lot.
A warm and moist habitat with lots of birds, snakes, and other smaller dinosaurs was the ideal habitat for this dinosaur.
Who did a Sinornithosaurus live with?
Evidence regarding the small size of this Chinese bird lizard is present at the Yixian formation. The small size of a dinosaur is a big liability for dinosaurs because it makes them vulnerable to be hunted by other big dinosaurs.
This venomous dinosaur lived and hunted in a pack. The birds of today's age such as the tawny eagle and tawny owl have the same hunting behavior as these dinosaurs, who now rest in the national Museum of China.
How long did a Sinornithosaurus live?
A lot of evidence regarding the lifespan is not known by Millenii or other scientists. Although according to natural history, it can be said that they had a life span of 10-12 years.
How did they reproduce?
 This venomous dinosaur is very similar to the reptiles of the current day. Although their teeth are more curved like theropods, the breeding habits are similar. They lay eggs and protect them like any other reptiles.
