Evolution of the cochlea and the elongated cochlea allows for better sensitivity for higher frequencies. As in all lepidosaurs and archosaurs, the single-ossicle (columellar) middle ear transmits sound to the footplate of the columella, which sends a pressure wave through the inner ear. In snakes, the basilar papilla is roughly 1mm long and only responds to frequencies below about 1 kHz. In contrast, lizards tend to have two areas of hair cells, one responding below and the other above 1 kHz. The upper frequency limit in most lizards is roughly 5–8 kHz. The longest lizard papillae are about 2mm long and contain 2000 hair
Stirrup jar jar offers two basic zones for decoration, the body and the shoulder. These are defined by concentric bands of color around the bottom and the top of the vase. The bands are present on nearly every stirrup jar, whether the canvases are painted or not. Sometimes the bands cover the entire body, and are the only decoration. The colors, generally red or brown on a cream or buff slip, are produced by hematitic inclusions in the paint. Evidence of the Linear B documents indicates that Stirrup jars were used as containers for olive oil. Speculations as to other content have
