It was a semi-arid landscape crossed by a number of braided rivers, and
containing occasional seasonal and semi-permanent lakes. Woody vegetation
was largely restricted to the banks of the rivers (including islands).

The woody vegetation was mainly coniferous, with an understory of
bennitites and cycads.  The inter-riparian areas may have been covered with
ferns, but that is less certain.

Some areas to the southeast of the Park has extensive sand dunes.
