A partial view of 16 feather barbs trapped within a single piece of Canadian amber. These specimens provide few clues about their potential bearer, but provide another tantalizing view of well-preserved pigments within the deposit. The overall colour of these specimens would likely have been medium or dark-brown / Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

A very specialized feather found alongside a plant bug within Canadian amber. This feather displays specialized structures (coiled barbule bases) that are only known in modern birds adapted to gather water with their feathers. In some cases, this helps the bird dive, by reducing its buoyancy, in other cases, belly feathers with this type of coiling are used to collect water and transport it to the nest /Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

A feather barb trapped within a spiders web in Late Cretaceous Canadian amber. This barb displays microscopic features that indicate it was once part of a vaned feather and was likely borne by a flying bird. This particular specimen began our search for additional feather inclusions in the amber deposit/ Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

Researchers from the University of Alberta have found never-before-seen protofeathers that they believe came from small theropod dinosaurs, predators that roamed southern Alberta about 80 million years ago. The protofeathers no longer exist on any creatures today and likely kept the small dinosaurs warm, researchers believe / Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

Within this amber piece, six feather fragments partially overlap each other. The beaded appearance of the barbules (finest structures) in this image is a result of pigments concentrated within just a portion of each of the segments that make up the barbules. These barbule segments or, internodes, are connected in a fashion similar to the segments in a bamboo shoot/ Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

Within this image, the basal coiling that is a structural adaptation for water uptake is shown in greater detail. Unfortunately, the bases of the barbules converge toward the viewer, so they are quite crowded in this image. Toward the bottom of the image, the feather breaches the surface of the amber piece, and is no longer preserved/ Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

A dark-field microphotograph that illustrates the apparent brown colour produced by pigments within the feather in amber. Much of the work on Canadian amber specimens has been limited by the technology available to observe the specimens. We have good indications of pigment intensity and distribution at a very fine scale, but large-scale colour patterns are elusive / Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied

An isolated barb that is structurally similar to those figured in 8HR, but lacks pigmentation. This specimen is largely visible as a result of being stuck within a drying line in the amber. The drying line is the darkened region within the amber, representing a surface where the resin was once exposed and partially dried. Found within the same piece of amber is a juvenile mite/ Photograph by: Department of Earth and Atmospheric Sciences, University of Alberta, Supplied
