Dinosaur tail found preserved in amber

Let us hope that more examples are found. Feathers are very expensive to keep (read need lots of time required to keep them in working order) so the benefit must of been huge. I wonder what the benefit was? Very cold climate? Need to run fast?
 
As always the stuff that's interesting is subtle
The feathers lack the well-developed central shaft - a rachis - known from modern birds. Their structure suggests that the two finest tiers of branching in modern feathers, known as barbs and barbules, arose before the rachis formed.

This helps draw a branch point in a cladogram.

I just can't get enough of the fact that dinosaurs were just big chicken.

You can't really point at any dinosaur and say that it is a chicken (bird) ancestor. The big, culturally-iconic dinosaurs are not chicken ancestors.
