Burgess Shale

In class we watched a video about the Burgess Shale. This is the name of the fossil field in Canada that was discovered in the early 1900's. When first discovered the fossils were mistaken for animals that exist in our world today. However, after more research they found that these fossils were not anything like the species found today. Also, the animals were non-vertebrates. This is find is rare because it's usually the bone imprints that scientists use to determine the animals. Also, the animals image is pressed into the earth, so somehow the animals were slowly preserved into the land, leaving there spineless image. Finding this field allows scientists to look back at the ways species have evolved over time.
