...University of California, Professor Charles Bernard Lipman, plant physiologist, took a chunk of pre-Cambrian rock. The piece came from Canada. Geologists considered it 100 to 200 million years old. Professor Lipman split the chunk and from the fractured surfaces scraped what he hoped were primeval microbes...
...Princeton University, Geologist B. F. Howell announced that a tiny fossil fishplate (scale) which he had picked the previous summer out of Cambrian strata in Franklin County, Vt., had been identified as belonging to a primitive fish, the earliest known creature to possess a notochord (rudimentary spine), which swam in the days of trilobites and brachiopods as the then (over 50 million years ago) highest form of animal life.

...indication of what might be accomplished is given by the recent report on the terranean strata of Harvard Hall.

Upon this base are laid numerous formations which at recurring intervals indicate an accumulation of debris from the most distant regions of the continent. Traces of Colorado gumbo, New Jersey sand, and Ohio clay were identified. The dominant type, however, was a dust...
...Arbuckle Mountain area of Oklahoma contains perhaps the most complete series of sedimentary rocks from before pre-Cambrian times in America, says Prof. C. E. Decker, of the University of Oklahoma. Folding and erosion have exposed the beds, with great fossil deposits, for study...
