“Scientists say they have discovered a "stunning" trove of thousands of fossils on a river bank in China.
The fossils are estimated to be about 518 million years old, and are particularly unusual because the soft body tissue of many creatures, including their skin, eyes, and internal organs, have been "exquisitely" well preserved.
Palaeontologists have called the findings "mind-blowing" - especially because more than half the fossils are previously undiscovered species.
The fossils, known as the Qingjiang biota, were collected near Danshui river in Hubei province.
More than 20,000 specimens were collected, and a total of 4,351 have been analysed so far, including worms, jellyfish, sea anemones and algae.
They will become a "very important source in the study of the early origins of creatures", one of the fieldwork leaders, Prof Xingliang Zhang from China's Northwest University, told the BBC.
Details of the findings were published in the journal Science on Friday.”

There a some very knowledgeable experts here on all kind of rocks so thought I’d ask if anyone here was familiar with this type of quartz crystal and what the host rock and inclusions might be? In the close up’s the gold color is a bit washed out and pale, but under a loop it’s at least interesting looking and crystalline in structure with a pleasant goldfish color. My wife bought them 10-15 years back although I’m not sure who she got them from she said the quartz came from Brazil, I don’t know anything else on their origin or value. They are cut and polished in a way to magnify the little bit of host rock matrix and little inclusions inside the quartz crystal.
