Product Information

Yellow feathers symbolize a person’s ability to see things through no matter what the obstacles in their way maybe because it takes great courage and strength of character to stand steadfast against any kind of opposition. This means that when bird feather symbolism from the spirit world shows up, perhaps you need some help seeing your situation more clearly or understanding where others are coming from because this color represents blessings, which come in many forms, even if they don’t seem obvious at first glance.

They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. [5] Plumology (or plumage science) is the name for the science that is associated with the study of feathers. [6] [7]Pterosaurs were long known to have filamentous fur-like structures covering their body known as pycnofibres, which were generally considered distinct from the "true feathers" of birds and their dinosaur kin. However, a 2018 study of two small, well-preserved pterosaur fossils from the Jurassic of Inner Mongolia, China indicated that pterosaurs were covered in an array of differently-structured pycnofibres (rather than just filamentous ones), with several of these structures displaying diagnostic features of feathers, such as non-veined grouped filaments and bilaterally branched filaments, both of which were originally thought to be exclusive to birds and other maniraptoran dinosaurs. Given these findings, it is possible that feathers have deep evolutionary origins in ancestral archosaurs, though there is also a possibility that these structures independently evolved to resemble bird feathers via convergent evolution. [112] Mike Benton, the study's senior author, lent credence to the former theory, stating "We couldn't find any anatomical evidence that the four pycnofiber types are in any way different from the feathers of birds and dinosaurs. Therefore, because they are the same, they must share an evolutionary origin, and that was about 250 million years ago, long before the origin of birds." [113] [114] [115] [116] But the integumentary structures of the anurognathid specimens is still based gross morphology as Liliana D'Alba pointed out. The pycnofibres of the two anurognathid specimens might not be homologous with the filamentous appendages on dinosaurs. [117] Paul M. Barrett suspects that during the integumentary evolution of pterosaurs, pterosaurs primitively lost scales and pycnofibers started to appear. [93] Witmer, L. M. (2009).
