Views in the 1930s
As background for later developments, this chapter will describe some of the reigning views from the latter 1930s concerning cells, membranes, proteins, and metabolic systems. A brief account of some of the methods then available is also included.
Some Pliocene Fishes from Kansas, Oklahoma, and Nebraska
served in dead specimens are the series of bright blue streaks on the scaleless portions of the dorsal and dorsolateral surfaces, the white anterior edge of the first dorsal fin, the silvery tongue, and the dark vertical bands on the dorsolateral surfaces, the latter seen only in feeding skipjack. The two size groups schooled together. School disruption occurred only during feeding. The fish swam with their mouths constantly agape. They were never observed to stop swimming. No rheotaxis was demonstrated.
Second Contribution to the Rexroad Fauna
A student of stratigraphy or paleontology who is unfamiliar with the Pliocene and Pleistocene deposits in southwestern Kansas, and with the exposures and fossil localities in this region is lost in trying to follow the recent literature pertaining to these deposits and their faunas. Many recent published papers have introduced new stratigraphic and faunal terms with no attempt to correlate these terms with previous work (see Fig. 1).
