          Abstract

          Resumen:En el presente estudio se describen e identifican dos dientes fósiles de tiburón provenientes de las Formaciones Santa Teresa al sur de la Península de Nicoya y San Miguel al sureste del Valle Central, en la parte central del país. Ambas formaciones geológicas corresponden a secuencias marino someras de edad Mioceno Inferior; estos hallazgos fósiles permiten correlacionar dichas secuencias con la Formación Río Banano, aflorante en la región Caribe, donde también se registra la especie Otodus (Megaselachus) chubutensis [Ameghino, 1901 a 1902].

          Translated abstract

          Abstract:In this study are identified and described two fossil shark teeth proceeding from the Lower Miocene of Santa Teresa Formation, at the southern Nicoya Peninsula and San Miguel Formation at the southeast area of the Central Valley, in the central part of the country. Both geological formations correspond to shallow marine sequences; and those founds permit to correlate them with the Rio Banano Formation, outcropping in the Caribbean region where, is also recorded the species Otodus (Megaselachus) chubutensis [Ameghino, 1901 a 1902].
