Small leaves represent this species. Unfortunately they are incom- 
plete, lacking the upper part. The leaves are large in size, but variable, 
with entire margins. The petiole is long and thick, with a width of about 
2 mm. 
The species was long confused with the European Miocene Cornus 
studeri Heer, a quite different form. Rhamnites knowltoni occurs in the 
Denver, Raton, and Wilcox. 
Occurrence. Ravenscrag beds, north branch Frenchman river, SE. I 
sec. 22, tp. 7, range 22, W. 3rd mer. 
Genus, Paliurus Jussieu 
Paliurus (?) sp. 
Plate V, figure 7 
A single specimen shows what appears to be some winged fruit resemb- 
ling that of Paliurus. The fruit is circular and disk-like, about 2-6 cm. 
in diameter but not complete, with the wing showing radial striations. 
For an account of a well-preserved Paliurus fruit and a discussion of 
the geograpliical and geological range of the genus See Berry, Am. Jour. 
Sci., vol. 16, pp. 39-44, 1928. 
Occurrence, Estevan, above coal bed. Burnt shale associated only 
with abundant circular lenticular fruits not determinable but possibly 
representing Ginkgo. SW. | sec. 6, tp. 8, range 3, W. 4th mer.
