Feather birds, Oviraptorosauria and Deinonychosauria. In 1998, the discovery of a feathered oviraptorosaurian, "Caudipteryx zoui", challenged the notion of feathers as a structure exclusive to Avialae. Buried in the Yixian Formation in Liaoning, China, "C. zoui" lived during the Early Cretaceous Period. Present on the forelimbs and tails, their integumentary structure has been accepted as pennaceous vaned feathers based on the rachis and herringbone pattern of the barbs. In the clade Deinonychosauria, the continued divergence of feathers is also apparent in the families Troodontidae and Dromaeosauridae. Branched feathers with rachis, barbs, and barbules were discovered in many members including "Sinornithosaurus millenii",
Build-A-Bird real life birds that fit your selections. What happened next in the game involved educational material about your bird's range and habitat. The visual representations of the birds, their body parts and the bird habitats were in colour and vivid for the time but lacked animation. Build-A-Bird Build-A-Bird (1986 or earlier) was educational software for the Unisys ICON II public school computer. It may have appeared on the ICON I or Unisys ICON III. Build-A-Bird was designed and developed by Ergonomics Lab, University of Toronto. Gameplay revolved around creating a bird by choosing from a selection of different body parts
