“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.

“A rare pink diamond has fetched SFr50.3 million ($50m; £38.5m) at auction, a record price per carat. Pink Legacy, weighing in at just under 19 carats, was bought by US brand Harry Winston at auction in Geneva. The price of around $2.6m per carat marked a world record for a pink diamond, according to the Europe head of auction house Christie's. It had been valued at between $30-$50 million before sale, and was bought after only five minutes of bidding. The diamond's new owners have rechristened it the Winston Pink Legacy.”

How rare is this? One of my customers has been finding native Michigan copper nuggets with his Minelab Equinox 800 and said I could share this amazing discovery. Kind of makes my nuggets look like dinks. What do you think something like this is worth?
All of these are among finds I have kept from the past. They have been in a storage unit. I am fascinated with geology but have trouble ID'g rocks and don't like to smash em. This is a lot of pics ... maybe too many?! Thanks in advance for all who take a moment to share their expertise. Much regards!
^ is this part of a thunderegg?
^ the shell of the rock above (part of a thunderegg?)
^ could this be a thunderegg or just jasper?
^ a pyrite next to my thumb, is the middle rock a chalcopyrite?
^ shell of the rock pictured below
^ assume this is a banded agate?
^ could it be a geode?
^ not a great pic -- this coloration is actually light to deep purple/ violet
^ heavy, as if a cannonball, damn near perfectly round
^ also heavy nearly round rocks
^ sunstone? found in a creek north of the Arctic Circle
^ can't even guess ... looks like a vein within a vein, what could that material be?
^ nature couldn't create such an indent, could it?
^ same stone as above ... is this a relic of sorts?
^ same stone as above
^ could this have been a spear head?
^ might this be a corondum?
^ same rock as above; what are those inclusions -- jasper? can't be rubies..
^ same as above
^ what happens when your 3 year old daughter finds your rocks!
