    Saw that. So it seems to be a forerunner of birds, testing out feather designs.
    Size of a mule. It would be pretty ferocious at that size. If it can't fly, I wonder if it could glide like some flightless birds do nowadays.

    Further details, very technical:

    One of the open questions about evolution is when warm-bloodedness began to develop. Feathers are good insulators, so flightless feathered reptiles may have been able to retain more body heat (e.g., after sunning themselves). Good example of how some feature or function later gets re-function-ed (e.g. for flight).
