-"Paleontologists were stunned when fossils appearing to belong to the soft-tissued embryos of marine creatures were unearthed in Chinese sediments a decade ago," says Science News.
-Tests are pointing to a process of three stages, two of which directly involve bacteria common in marine sediments, can reproduce the same fossilization effect in modern embryos.
-"First, the fragile embryonic tissues must end up in an oxygen-poor environment that shuts down autolysis, the enzyme-driven process that, in essence, digests the cell from the inside out," says Science News again.
