postparietal fenestrae lost

["Ken Kinman" <kinman@hotmail.com>]

    On September 10th, Jaime listed the loss of postparietal fenestra(e) as 
a synapomorphy of Dinosauria.
    Is this the pair of fenestrae caused by the incomplete fusion of the 
supraoccipital with the parietals (fusion which is presumably completed only 
once---- at or near the origins of Dinosauria)?
    I am especially wondering if postparietal fenestrae are found 
throughout crurotarsi (including parasuchians).
