From the Fish Bed, they recorded the following plants, the identifi- 
cations being those of Mr. W. S. Dun : — 
Tceniopteris Daintreei, McCoy. 
Podozamites lanceolatus, L. & H. 
Thinnfeldia odontopteroides , Morris. 
Thinnf eldia sp. 
Taxites (cf. T. planus, Feistmantel). 
N europteridium australe (?), Tenison-Woods. 
Sphenopteris sp. 
In addition they also quote the following species as having been 
determined by the late Mr.. R. Etheridge, junior, among the material collected 
by Mr. Cullen : — 
Thinnfeldia odontopteroides, Morris. 
Tceniopteris Daintreei, McCoy. 
Podozamites lanceolatus, L. & H. 
Podozamites spathulatus, Feistmantel. 
Podozamites longifolius, McCoy. 
Podozamites sp. 
With regard to the stratigraphical position of the Beds their conclusions 
(p. xiii) may be quoted : “ The stratigraphical evidence obtained would seem 
to indicate that these beds were deposited in a hollow of erosion in the sand- 
stones of the Hawkesbury Series, for the following reasons : — 
(1) . The Fish Beds differ in lithological character from any rock know] 
to occur elsewhere in the Hawkesbury Series. 
(2) . They thin out rapidly against the sandstone of the latter formation 
which rises to a considerable height on their margin, and is nowhere 
seen to overlie them.” 
In their opinion the balance of evidence is in favour of a Jurassic age 
for the Fish Beds. This was supported by Mr. A. S. Woodward’s conclusion 
from an examination of the fish, of which all the species described were new, 
that “ The Talbragar fish-fauna is, therefore, probably not earlier than the 
Upper Lias, and may be referable to the Lower Oolites.” 1 
Mr. W. S. Dun, in a paper “ Notes on the Australian Tceniopteridece ’ 
(Aust. Assoc. Adv. Sci., vii (1898), p. 384) records the occurrence of Tceniopteris 
sp. and Phyllopteris sp. from Cockabutta Mountain, and of Tceniopteris
