 The
Green River Formation deposits of Wyoming, Colorado, and Utah are
best known for their immaculately-preserved fish, but other examples
are known as well, as this specimen attests. This is an example
of a pair of downy feathers from an unknown bird. Downy feathers
are the ones that are found closest to the skin; their hairlike
structure provides excellent insulation. The specimen is rendered more
interesting by the well preserved insect
near the upper left of the feather. |
