15 صفحه اولEyes fossilized
Fossilized insects are normally two-dimensional, because the exoskeleton tends to collapse during decay. The remarkable specimens shown above have been preserved in three dimensions because of the unusual conditions under which they formed. The images are scanning electron micrographs of the eyes of fossilized beetles from the Tertiary period, found in limestone at a site in northwest Queenslan...
متن کاملA two-headed reptile from the Cretaceous of China.
A malformed embryonic or neonate choristoderan reptile from the Lower Cretaceous Yixian Formation of northeastern China is described. The tiny skeleton exhibits two heads and two necks, with bifurcation at the level of the pectoral girdle. In a fossil, this is the first occurrence of the malformation known as axial bifurcation, which is well known in living reptiles.
متن کاملNovel Virophages Discovered in a Freshwater Lake in China
Virophages are small double-stranded DNA viruses that are parasites of giant DNA viruses that infect unicellular eukaryotes. Here we identify a novel group of virophages, named Dishui Lake virophages (DSLVs) that were discovered in Dishui Lake (DSL): an artificial freshwater lake in Shanghai, China. Based on PCR and metagenomic analysis, the complete genome of DSLV1 was found to be circular and...
متن کاملFossilized lithospheric deformation revealed by teleseismic shear wave splitting in eastern China
Global mantle convection significantly impacts the processes at Earth’s surface and has been used to gain insights on plate driving forces, lithospheric deformation, and the thermal and compositional structure of the mantle. Upper-mantle seismic anisotropy has been widely employed to study both present and past deformation processes at lithospheric and asthenospheric depths. The eastern China r...
