Life reconstruction of Jianianhualong tengi



The Middle-Upper Jurassic and Lower Cretaceous of western Liaoning and neighbouring areas have produced spectacular fossil remains of theropod dinosaurs, particularly of maniraptoran theropods, which are critical to our understanding of bird origins. Among them are many fossils of troodontids, which are considered as the closest relatives of birds either on their own or together with dromaeosaurids. Reported troodontid species include Sinovenator changii, Mei long and Sinusonasus magnodens from the early Aptian Yixian Formation (the middle section of the Jehol Group), Jinfengopteryx elegans from the Hauterivian Dabeigou/Dadianzi Formation (the low section of the Jehol Group), and Anchiornis huxleyi, Xiaotingia zhengi and Eosinopteryx brevipenna from the Oxfordian Tiaojishan Formation. Significantly, the discoveries of the latter four taxa provide direct evidence for the presence of feathers in troodontids, which shed new light on the early evolution of pennaceous feathers. However, several recent phylogenetic studies have questioned the troodontid affinities of these species, and thus feathers have yet to be found in an unquestionable troodontid taxon.

This new troodontid described is from the Yixian Formation of Baicai Gou, Yixian County, western Liaoning preserving large feathers along the forelimbs, hindlimbs and tail that have a distribution pattern similar to other basal paravians such as Microraptor, Anchiornis and Archaeopteryx. Its discovery is highly significant in reconstructing both the skeletal and integumentary evolution of troodontids, and the more inclusive paravians.

Interesting,  well that's why it's called the Middle Kingdom...

However, I might be wrong; but it appears that their is an image known as a Hinomaru,
a red circular dot just below the eye.

`this image is a restored pic, not the actual. in my opinion, since this new dinosaur was feathered, the image might be based on the restored pics of archaeopteryx who has red dot below and red feather around its eye.

`middle kingdom... do you means China? middle kingdom sounds weird, and now China is not ruled by a king or queen, so it is not a kingdom.

The term 'Middle Kingdom' does not imply that China is superior to other peoples and nations around it — China just happens to be located in the Middle.  中国 (Zhongguo)


China really is the Middle Kingdom – literally, and for much longer than we ever knew, scientists say.

China, whose own name translates as Middle Kingdom, was located in the centre of the world’s the first super continent, called Nuna, 1.8 billion years ago – cocooned by other ancient plates that later broke off to North America, India, Australia and others.

A joint study by mainland and British scientists has now drawn a new map for the planet’s early geophysical history that could provide useful clues to a wide range of scientific issues, from the formation of mineral deposits to the evolution of life.

The study was published in the journal Nature Communications.
