“The fossil plants whose description form the subject of this paper were 
collected by their discoverer, IMr. J. W. Harvey, of Glen Rose, Texas. They 
occur in the bed of the Paluxy River, two miles above Glen Rose. The 
material containing the fossils is a pretty firm limestone, quite free from 
sand and clay, and light gray in oolor, which was evidently a deposit 
formed at a considerable distance from the shore. This necessitated a 
prolonged immersion of the plant remains in water and their transporta- 
tion over long distances. This conclusion, drawn from the nature of the 
sediment, is confirmed by the condition and character of the plant fossils.

“Most of the fossils are in the formi of small fragments. Cones of conifers 
land bits of twigs of the same much predominate. The twigs have usually 
thick leathery leaves and a dense durable epidermis^ These facts indicate 
that the plants and parts of plants that can withstand long drifting are 
predominant, because more perishable forms were destroyed in transporta- 
tion. 'Oonifers of certain types are most common, probably because, under 
the existing conditions, they were best fitted for preservation, and not 
because they were most common in the flora.” P. 261.
