Me too. But I think this dynamic view of territory is more useful in
thinking about cretaceous days than a fixed site.  Along these lines, I
read that Sternberg predicted that dino nests would be found more often in
"uplands".  Horner took this advice and hit paydirt.  Was this an active
prediction or did it stem more from just not being able to find eggs in
lowlands?  What hypotheses could be formed for colonial nesters seeking
upland environments?
