DOWELD A. B. New Syllabus of Plant Families (A Plant World System).
Approx. 500 p. Hardbound; 21 cm x 29 cm PRICE: 150.00 EURO/US $166.67

The Syllabus covers all
known plants, including fossil, for the period of cca. 4700 million years
(from Precambrian to Extant),

Umm, maybe I'm completely out of date, but I didn't know there were any Hadean
rocks around to find fossils in. Just how old are the oldest rocks, these
days, and just how old are the oldest fossils (presumably of bacteria-like
things)?
