  Motivated in part by the recent observation of liquid glass in suspensions of
ellipsoidal colloids, we examine the structure of jammed ellipse packings over
a much wider range of particle aspect ratios ($\alpha$) than has been
previously attempted. We determine $\phi_{\rm J}(\alpha)$ to high precision,
and find empirical analytic formulae that predict $\phi_{\rm J}(\alpha)$ to
within less than 0.1% for all $1 \leq \alpha \leq 10$, for three different
particle dispersities. We find that the densest packings possess
unusually-well-defined nearest-neighbor shells, including both a higher
fraction $f_{\rm Z = 6}$ of particles with exactly six contacts and a
previously-unreported short-range order marked by ``kinetically suppressed''
regions in their positional-orientational pair correlation function $g(r,\Delta
\theta)$. We also show that the previously-reported approach to isostaticity
(coordination number $Z_{\rm J} \to Z_{\rm iso} \equiv 6$) with increasing
$\alpha$ is interrupted and then reversed as local nematic order increases:
$Z_{\rm J}(\alpha)$ drops towards 4 as ellipses are more often trapped by
contacts with a parallel-oriented neighbor on either side and a
perpendicularly-oriented neighbor on either end. Finally we show that
$\phi_{\rm J}/\phi_{\rm s}$ (where $\phi_{\rm s}$ is the saturated RSA packing
density) is nearly $\alpha$-independent for systems that do not develop
substantial local hexatic or nematic order during compression.
