10 QUEENSLAND FOSSIL FLORAS 
Coal Measures and the Upper Coal Measures, the two being 
separated by a series of marine deposits. It does not seem 
possible at present to separate the two series of Coal 
Measures by their floras, nor can we say just which forms 
occur in each Series, but there is no doubt of the presence 
of the typical Glossopteris Flora in each.

The name Permo-Carboniferous in Australia arose 
under a misapprehension, and there has been considerable 
discussion during the past few years as to the advisability 
of discarding it. There is a more or less general agreement 
that the term is not a good one, but the difficulty lies in 
fixing the dividing line between Carboniferous and Permian. 
It is possible that the lower portion of the so-called Permo- 
Carboniferous System may be Carboniferous, but the faunas 
of the Lower and Upper Marine Series are very similar to 
one another, and both are very different from the 
Carboniferous fauna in Eastern Australia; in addition, 
the floras of the Lower and Upper Coal Measures can
