    Layers of the Grand Canyon During the earliest periods of the Grand Canyon formation where we have Tapeats sand stone‚ bright angel shale and muav limestone it would appear that there was a relatively shallow‚ warm sea. This is indicated by the presence of Trilobite fossils found in this layer which thrived in that environment. Trilobites were early animals that had exoskeletons that are usually the only part of them that is preserved in the fossil record. They were marine bottom feeders who thrived

    the slurry to be placed on the glass plates. A guide allows the applicator (with an adjustable layer thickness gauge) to be pulled along the glass plates as the slurry is dispensed. Some practice is needed to get a continuous body motion pulling the applicator across the plates to get an even layer. The glass plates must be the same thickness and extremely clean. Any oil or grease will result in a poor layer. Handle the plates with rubber gloves when washing or rinsing. Care is also needed if the edges

    unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol
