Have you ever wondered if a rock you've had sitting around for years is worth anything? What about a piece you think may be a fossil from an old animal?
Students at the South Dakota School of Mines and Technology were answering those questions at their Fifth Annual Fossil I-D Day. Members from the Tech Geological Association and the Paleontology Club on campus teamed up to identify people's discoveries and answer their questions.
Tech Geological Association President Hallie Bower says, "We get both rocks and fossils more fossil fragments from people that have found them, sometimes rocks that can be common or uncommon. Today, we've had someone that brought in a fossilized egg. We had a couple that were a few jaw bones that were brought in, some low quality agates, someone brought in a core from Keystone that had some gold in it. We've had some good stuff today."
This was held at the Museum of Geology, and according to museum staff, quartz is the most common rock brought in for identification.
