6 QUEENSLAND FOSSIL FLORAS 
such criticism might be applied are the exception rather 
than the rule. The careful and detailed work of a large 
and increasing number of paleobotanists in the present 
century raises the hope that we have seen the last of even 
such exceptions, for there is no longer any excuse for. 
inaccurate work. 
In Queensland fossil plants occur in greater or less 
abundance on a number of horizons, and, in general, the 
assemblage of forms in each Series is sufficiently character- 
istic to enable it to be distinguished as belonging to that 
Series. 
There are representatives of two floras of Paleozoic 
age, five of Mesozoic age, and possibly a number of Cainozoic, 
but we are unable, at present, to separate the Cainozoic 
flora into groups representing different horizons. The 
following table, representing portion of the Geological 
Reeord for Queensland, will serve to indicate the horizons 
on which fossil floras occur :-—
