Seg\u00fan un art\u00edculo publicado por El Tribuno, muchas paredes y veredas de la ciudad de Salta tienen f\u00f3siles y marcas sedimentarias que casi nadie advierte. Algunos pisos de edificios c\u00e9ntricos, como bancos y hoteles, llevan calizas con amonites y belemnites, antiguos cefal\u00f3podos marinos. Esas rocas llegan de Cuyo o la Patagonia, porque en el norte argentino no hay de ese tipo.<\/p>\n

Las rocas locales tambi\u00e9n tienen lo suyo. Las lajas verdes de la Formaci\u00f3n Puncoviscana, extra\u00eddas de los alrededores de la ciudad, conservan huellas de gusanos y otros animales de cuerpo blando, y contienen el l\u00edmite entre el Prec\u00e1mbrico y el C\u00e1mbrico. Fueron estudiadas por el paleont\u00f3logo alem\u00e1n Alfred Seilacher y por Gilberto y Guillermo Ace\u00f1olaza. Esas lajas se ven adem\u00e1s en Cachi, Campo Quijano, San Antonio de los Cobres y Tolar Grande.<\/p>\n

Desde la sierra de Mojotoro y el cerro San Bernardo salieron areniscas del Ordov\u00edcico, de unos 470 millones de a\u00f1os, con marcas de trilobites llamadas cruzianas. Aparecen en el monumento a G\u00fcemes y en casas antiguas. El Hogar Escuela se levant\u00f3 con lajas de la cantera La Pedrera. El texto advierte que muchas de esas piedras, con dibujos de manganeso que no son f\u00f3siles, est\u00e1n vandalizadas con aerosoles.<\/p>\n
