*Epidendrosaurus* derives from the older Daohugao fauna of Nei Mongol,
not Liaoning, and would be between the Middle and Late Jurassic, but so
far dating has not corroborated any Early Jurassic age. The age for
*Scansoriopteryx* is unknown, as the slab was never dated to locality or
horizon, and was purchased in a rock show. We don't even have a
"collector" to show us where the slabs came from.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
