Let $Fto Xto B$ be a fiber bundle (of smooth manifolds) with fiber $F$ and base $B$. As a set, we may write
$$
X=bigcup_bin BF_b
$$
where $F_b$ denote the fiber at $bin B$.
Is there a canonical way to describe
$$
bigcup_bin B T^*F_b ~textor~ bigcup_bin B TF_b
$$
as some new fiber bundle over $B$?
I attempt to consider $T^*X$ or $TX$ but we have also horizontal parts; the above sets only consists of vertical parts. I guess the fiber bundle structures on the above sets depends on some choices and may not be canonically constructed; but I have no idea how to understand it.
