We have a number of excellent specimens of Caudipteryx at the IVPP, though only this one example on display. It shows off just how frustrating these things can be – it’s the best preserved Liaoning oviraptorosaur I know of, with very well preserved bones, feathers and a complete set of gastroliths, but the head and neck is missing as well as the tip of the tail. Ah well, can’t have everything (apparently).
Still, the feathers here are rather nice so here’s a couple of snaps of them, though the glass and position of the specimens means they are not great, sorry about that. One day more museums will actually consider, you known, the people who want to see the specimens when they design the display.
Anyhow, Caudipteryx is most notable for the long feathers on the forearm and manus and the fan of feathers on the tail, though as can be seen in various specimens there were feathers over much of the body. Here are a couple of close-up (well, as far as possible) showing off the arm feathers, though some of those from the chest are also visible. Also in shot are the gastroliths (stomach stones).
