Humming birds are one of the most interesting animals in the world. Some of them are so small that they are often mistaken for bumblebees. They're known to dive underwater and quickly dive right out while flying, and they eat more than they weigh to prepare their travel across an entire ocean non-stop. On top of all of this, they can be pretty rare depending on where you live, and they're really fun to watch.
Hope this helps you out :)
The Burgess Shale is a rock formation that is known for having an abundance of soft bodied organisms preserved in shale. This formation is significant because it preserves organisms from the Cambrian Explosion. The Cambrian Explosion is a period in time that coincides with the Pre- Cambrian- Cambrian boundary around 542 million years ago. The period represents an unusually rapid radiation of organisms.
Fossils of the Burgess Shale are thought to be well preserved because most were thought to be buried fairly rapidly and in conditions that had little or no oxygen. The rate of decomposition is slowed in these conditions so soft body parts of the organisms were preserved for millions of years in the mud-stone that eventually became lithified to shale. <span />
