Tertiary Coniferous Woods Of Western North America, George F. Beck
Tertiary Coniferous Woods Of Western North America, George F. Beck
All Faculty Scholarship for the College of the Sciences
Almost four decades have elapsed since Platen (1908), the German paleobotanist, published his report upon the fossil woods of the western United States. Since then no over-all treatment of these materials has been attempted. although Platen overlooked the Pacific Northwest with its abundance of Tertiary petrified woods. The purpose of this paper is to bring knowledge of the western coniferous woods of the Tertiary up to date. In this effort the writer recognizes that much of this information has been accumulated incidentally in the study of the Russell Petrified Forest series of central Washington, and that it is not as …
Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck
Nyssa Woods Of The Pacific-Northwest Tertiary, George F. Beck
All Faculty Scholarship for the College of the Sciences
The nyssa gums are one of the modern genera of trees most certainly present among the petrified woods and forests of the Pacific Northwest. Almost every collection from the mid-Tertiary of this region contains a few specimens of typical tupelo or sour gum. These are fine-grained woods which to the unaided eye may be mistaken for conifers.
Ancient Maples Of The Central Washington Region, George F. Beck
Ancient Maples Of The Central Washington Region, George F. Beck
All Faculty Scholarship for the College of the Sciences
When I began work on the petrified logs of the general Vantage area some 13 years ago, it became apparent at once that maple-like woods are commonplace in the main (Vantage) raft forest and slightly less abundant in two rooted units of the Yakima Canyon. So widely do these woods range throughout the structural variations found in modern maples that little success has attended the efforts to assign them to nominal species. The extremes can readily be established but few hints exist as to the boundaries between them.
Two Newly Discovered Conifers, George F. Beck
Two Newly Discovered Conifers, George F. Beck
All Faculty Scholarship for the College of the Sciences
Two genera of coniferous wood, apparently not listed among the Tertiary woods of the western states, have been recognized in the Percy Train collections from Rainbow Ridge, northwestern Nevada. These two, Tsuga (hemlock) and Chamaecyparis (cedar) bring up to 14 the genera of coniferous wood more or less certainly identified from the period and area in question.
Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck
Status Of Tertiary Woods Of The Western States Representing The Juglandaceae, George F. Beck
All Faculty Scholarship for the College of the Sciences
For many years there has been uncertainty concerning the generic status of some fossil leaves belonging without question to the walnut family as a whole. A review of the woods of Juglandaceae as they have appeared in Tertiary horizons of the western states has suggested which genera are present, and in what proportions their leaves (or other remains) might be expected to appear.
Spruce In The Western Miocene, George F. Beck
Spruce In The Western Miocene, George F. Beck
All Faculty Scholarship for the College of the Sciences
One of the real surprises in store for us as we began to section specimens of petrified wood from the Vantage and certain other horizons in Central Washington, was the prevalence of a spruce type hardly hinted at in the leaf lists as published for the various sediments of Yakima time (upper miocene?).
Exotic Ancient Forests Of Washington, George F. Beck
Exotic Ancient Forests Of Washington, George F. Beck
All Faculty Scholarship for the College of the Sciences
The greatest fossil forest in the world is located within easy driving distance of the University of Washington campus in the State of Washington, near the Columbia River, east of the city of Ellensburg. Mr. George F. Beck, a member of the faculty of the Ellensburg State Normal School, and a former graduate student of the College of Forestry of the University of Washington, discovered this forest, which is now known as the Ginkgo Forest State Park. Aside from its importance from a scientific point of view, this "petrified forest," which contains a greater variety of species than any other …
