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: New Method of Characterizing Graphene

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.

Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
