[Taxacom] Fossil Plant IDs

[Herbarium]

A colleague of mine is writing a book on the various types of rock used in 
building construction in the U.S.  He would very much appreciate any 
insights others may have on the genera of plants shown in the image links 
provided below.  They are from travertine rock quarried from Italy.
   For background info, he says, "In terms of depositional environment, the 
travertine was deposited in Tivoli, about 20 miles east of Rome, roughly 
250,000 to 140,000 years?ago. The rock is still being deposited there in 
hot springs. I don't?have any more specific dates than these. The springs 
generated lakes,?ponds, and swamps, where deposition occurred.

   Any help is much appreciated.
