The most primitive confuciusornithid bird from China and its implications for early avian flight

08.05.2008
Professor Zhang FuCheng and his colleagues discovered and named a new confuciusornithid bird, Eoconfuciusornis zhengi, gen. et sp. nov. that lived 131 million years ago.

It is the most primitive member of Family Confuciusornithidae and thus extends the lifespan of this family to 11Ma. In addition, Eoconfuciusornis and its relatives have many osteological transformations and represent an early adaptation toward improved flight in the evolution of Confuciusornithidae.

This paper is published in volume 51, number 5 (May, 2008) of Science in China, and the authors are Zhang FuCheng, Zhou ZhongHe and Michael J BENTON.

Confuciusornithids are a basal bird group that lived from 120¨D125 million years ago. Eoconfuciusornis belongs to confuciusornithids for possessing some key characters such as the toothless upper and lower jaws and the forked rostral end of mandibular symphysis.

Eoconfuciusornis and its relatives show many osteological transformations, for instance, the increase in the size of deltopectoral crest of the humerus and of the keel of the sternum. These features provide osteological evidence for increasing flight power throughout the 11 million years of confuciusornithids' evolution.

IVPP is short for "Institution of Vertebrate Paleontology and Paleonanthropology", which is a research institute under the Chinese Academy of Sciences with many renowned vertebrate paleontologists and important collections.

Im Focus: Full speed ahead for SmartEEs at Automotive Interiors Expo 2019

Flexible, organic and printed electronics conquer everyday life. The forecasts for growth promise increasing markets and opportunities for the industry. In Europe, top institutions and companies are engaged in research and further development of these technologies for tomorrow's markets and applications. However, access by SMEs is difficult. The European project SmartEEs - Smart Emerging Electronics Servicing works on the establishment of a European innovation network, which supports both the access to competences as well as the support of the enterprises with the assumption of innovations and the progress up to the commercialization.

It surrounds us and almost unconsciously accompanies us through everyday life - printed electronics. It starts with smart labels or RFID tags in clothing, we...

Im Focus: Energy-saving new LED phosphor

The human eye is particularly sensitive to green, but less sensitive to blue and red. Chemists led by Hubert Huppertz at the University of Innsbruck have now developed a new red phosphor whose light is well perceived by the eye. This increases the light yield of white LEDs by around one sixth, which can significantly improve the energy efficiency of lighting systems.

Light emitting diodes or LEDs are only able to produce light of a certain colour. However, white light can be created using different colour mixing processes.

Im Focus: Quantum gas turns supersolid

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.

Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

Im Focus: Quantum simulation more stable than expected

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.

Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
