Burrum Series is of Lower Cretaceous age; the Maryborough Series is usually 
classed as Cretaceous, but attention has already been called to the possibility 
that it may be Upper Jurassic. 1 
Two species have been described from the Burrum Series, 2 viz. : — 
P. Jemmetti and P. peregrinum (?). 
Cones. 
(1) . The specimen (F3168) figured on Plate VI, fig. 8, shows the 
impression of portion of a small cone. The cone was probably about 5 cm. 
long and 2 cm. in diameter; the scales were spirally arranged, the impressions 
of their outer ends being rhomboidal in outline (about 3 mm. by 1 mm.). 
Determination of such cone impressions is impossible, and it can only 
be suggested that the present example may be Araucarian, as it is of somewhat 
similar type to cones occurring in the Jurassic of Australia, which show more 
definite evidence of Araucarian affinity. 
(2) . The small cone (?) figured on Plate VI, fig. 7, is another example 
with which it is impossible to deal satisfactorily. It shows ten or twelve small 
ovate bodies (possibly seeds) attached to a slender axis, the shape of the whole 
structure being rather elongate oval. 
(3) . Another specimen (F3163) which appears to represent a cone, 
possibly in transverse section, is figured on Plate VI, figs. 4, 4 a. It is oval, 
tending towards circular, in shape, and shows nine, small, circular bodies 
arranged round a central axis. The specimen is simply an impression, without 
preservation of any details of structure. 
? Coniferous fragments. 
A number of specimens (of which three are figured) are apparently 
coniferous, but they give very little indication of their affinities. Their 
general appearance suggests a comparison with Elatides, but this is only a 
suggestion — two of the figured examples (F3165, F3164A), Plate VI, figs. 5, 
6, resemble foliage shoots, whilst the third (F3160), Plate VI, fig. 3, 
may possibly be a cone. Comparison is suggested with examples from the 
Jurassic of Sutherland, Scotland, figured by Seward. 3
