mm, with a rounded or obtusely pointed apex and 
smooth surface apart from a prominent vertical 
ridge (on internal casts). 
Description 
Isolated seeds of indeterminate affinity. Seeds 
ovate to elliptical, reaching 5 mm wide, 7 mm long, 
wings absent; internal casts ovoid (Figures 9H-K). 
Prominent vertical ridge commonly evident on 
internal casts but surface otherwise lacks 
ornamentation (Figures 9F,J,K). Base truncate or 
rounded, apex rounded or closing to an obtuse 
point. 
Comments 
Seeds of this type are common in the BuOsbrook 
Formation and are frequently preserved in 
association with Taeniopteris daintreei leaves 
although no physical connection is evident. White 
(1981, 1986) figured similar though smaller seeds 
with a longitudinal ridge preserved in 
pentoxylalean ( Carnoconites) cones from the 
Jurassic Talbragar fish beds in New South Wales. 
Seeds belonging to Carnoconites cramvellii Harris, 
1962 fruits from the Victorian Early Cretaceous 
(Drinnan and Chambers 1985) are also 
substantially smaller (1 mm diameter) than the 
Western Australian seeds and differ by their 
polygonal outline. This may simply be due to 
crowding of seeds in the Victorian cones. Larger, 
more loosely packed Carnoconites cones may have 
borne more rounded seeds like White's (1981) 
examples from Talbragar. Seeds of Carnoconites 
compactum Srivastava, 1946 are similar in size 
although the species was defined upon 
permineralized material which does not clearly 
show the seed shape in lateral view (Sahni 1948; 
Vishnu-Mittre 1953). Compressed Carnoconites 
laxum Harris, 1962 fruits from New Zealand show 
only indistinct seeds not favourable for comparison 
to Carpolithes bullsbrookensis. Carpolithes sp. B of 
Bose and Banerji (1984) has a longitudinal ridge 
like C. bullsbrookensis but is much larger with an 
acute apex. Seeds belonging to Rissikia 
talbragarensis White, 1981 are of similar size to C. 
bullsbrookensis but lack a longitudinal ridge. 
Winged conifer seed

Guppy; figure 25. 
Material 
WAM P.89.191. 
Distribution 
Broome Sandstone (Neocomian-Barremian), 
Canning Basin. 
Description 
Seed positioned basally on wing, wrinkled, 
ovate, c. 3.5 mm wide, 5 mm long. A flange (<1 
mm wide) around lateral margins of seed expands 
distally to form the 8.5 x 17 mm longitudinally 
striate oblong wing (Figure 10A). 
Comments 
The single available seed impression differs from 
those figured by Drinnan and Chambers (1986) 
from the Victorian Cretaceous by its distally 
expanded wing. The basal part of the seed has 
broken away leaving only a small portion of the 
fertile body. The seed does not show organic 
connections to any other plant remains and its 
affinities remain uncertain.

Material 
WAM P.96.8. 
Distribution 
Broome Sandstone (Neocomian-Barremian), 
Canning Basin. 
Description 
Axis impression bearing spirally arranged, 
broadly elliptical, leaf scars. Leaf scars 4 mm wide, 
2 mm tall, lacking obvious vascular strands. Scars 
raised above surface of axis (on cast), separated by 
0.5 mm grooves; arranged in 35° right-handed 
spirals, 50° left-handed spirals measured with 
respect to axial direction. Leaves and anatomical 
details not preserved. 
Comments 
The single stem fragment (upper right of Figure 
5E) is similar to a number of Jurassic and 
Cretaceous axis casts assigned to Bucklandia Presl 
(in Sternberg), 1825. White (1961a) figured a larger 
axis from the same locality (Gantheaume Point, 
Broome) showing well developed spirally arranged 
elliptical leaf scars. The Western Australian 
examples lack the anatomical details necessary for
