Chinese scientists' latest findings in ancient seabed community illustrate a biological mechanism capable of shaping community structure, operating beyond passive environmental constraints or initial larval settlement preferences, and highlight the potential for subtle anatomical features to exert significant ecological influence in deep time, according to a research article published on Monday by the Proceedings of the National Academy of Sciences of the United States of America (PNAS), a leading scientific journal in the world.
BEIJING, Jan. 25 (Xinhua) -- Chinese archaeologists have discovered a batch of fossils of multicellular eukaryotes that date back to 1.63 billion years ago, setting the world's oldest record of such fossils.
In a study published in Science Advances on Jan. 24, researchers led by Prof. ZHU Maoyan from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences reported their recent discovery of 1.63-billion-year-old multicellular fossils from North China.
A new study has shown that cicadas about 100 million years ago had yet to learn to produce the iconic buzzing sound that now characterizes summer days.
An international team of scientists said a fossil dating back to about 130 million years ago suggests male mosquitoes likely sucked blood in ancient times.
Researchers found these ancient bloodsuckers entombed in amber, which had been collected 15 years ago in central Lebanon. They represent the oldest known mosquito fossils yet found.
An international research team led by Prof. ZHANG Huaqiao from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) has reported the discovery of extraordinary early Cambrian (ca. 535 million years ago, or Ma) microfossils preserving the introvert musculature of cycloneuralians, a group of animals that include roundworms, horsehair worms, mud dragons, and many other creatures.
The findings link the Mesoproterozoic Horodyskia moniliformis with Ediacaran Horodyskia minor specimens, reinforcing their biogenicity and suggesting they represent a colonial giant-celled protist, possibly a coenocytic alga. This reveals an ancient and stable macrofossil taxon and shows coenocytic and colonial body plans dating back at least 1.48 billion years.
PANG Ke set aside some time to discuss the group’s findings with SCINQ.
Researchers from China and the United Kingdom have discovered fossils of a previously unknown eurypterid, more commonly referred to as a sea scorpion, dating back 450 million years to the Ordovician period in east China's Zhejiang Province, the earliest recorded in the country.
