  We consider scaling limits of random quadrangulations obtained by applying
the Cori-Vauquelin-Schaeffer bijection to Bienaym\'e-Galton-Watson trees with
stably-decaying offspring tails with an exponent $\alpha$ in (1, 2). We show
that these quadrangulations admit subsequential scaling limits wich all have
Hausdorff dimension $\frac{2\alpha}{\alpha-1}$ almost surely. We conjecture
that the limits are unique and spherical, and we introduce a candidate for the
limit that we call the $\alpha$-stable sphere. In addition, we conduct a
detailed study of volume fluctuations around typical points in the limiting
maps, and show that the fluctuations share similar characteristics with those
of stable trees.
