At least three 'seed fern' lineages appear in Early Cretaceous deposits in 
southern Australia (Pentoxylalean, Bennettitalean, Corystosperm) ranging 
from 142 to 115 MYA. 

I'm not surprised to see Stephen McLoughlin's name at the start of the list 
of authors:
http://www.amjbot.org/cgi/content/abstract/95/4/465
He's done a lot of great work on the Mesozoic flora of S.E.Australia over 
the years.
