Tonian new carbonaceous materials indicate that Horodyskia is among the oldest multicellular macro-organisms

　　Horodyskia, characterized by a string of beads with uniform size and spacing, represents one of few examples with a fossil record extending from the early Mesoproterozoic Era (~1.48 Ga) to the terminal Ediacaran Period (~550 Ma). Horodyskia also has a wide global distribution, but its biolog...

Fossil Pollen 'Sunscreen' Proves Role of Ozone Depletion in Largest Mass Extinction

　　Scientists from China, Germany and the UK led by Prof. LIU Feng from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) have revealed that pollen preserved in 250-million-year-old rocks contains abundant compounds that function like sunscreen but a...

Mesozoic Musicians: High acoustic diversity and behavioral complexity of Mesozoic katydids (bush crickets)

　　Acoustic communication has played a key role in the evolution of animals especially vertebrates and insects, ranging from mating to warning calls and even including social learning. On December 13, 2022 PNAS published the novel insight from an international team of paleoentomologists on acou...

New evidence proves saccorhytus is ecdysozoan

　　An international research team led by Dr. ZHANG Huaqiao from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) has used hundreds of new fossil specimens to clarify the anatomy and evolutionary affinity of Saccorhytus, originally thought to be a de...

The earliest known brood care in insects found in Daohugou biota

　　Parental care refers to the protection, care and feeding of eggs or offspring by parents, is considered as a significant behavioural adaptation in life-history traits. It has evolved independently multiple times in animals, e.g. mammals, birds, dinosaurs and arthropods, especially various li...

Mercury evidence of Deccan volcanism driving the Latest Maastrichtian warming event

　　The timing and ecological impacts of the Deccan large igneous province eruption are vigorously debated. About 150–300,000 years before the end-Cretaceous mass extinction, the Deccan basalt had already begun to erupt. Deccan large igneous province emitted a large amount of greenhouse gases s...
