本文描述了智利中部瓦尔帕莱索地区Horcon组上新世晚期地层中的12种软骨鱼类化石，并讨论了先前记录的古生物地理学和古环境意义。动物群包括Callorhinchus sp.，Heterodontus sp.，Carcharodon carpidas，尖吻Isurus oxyrinchus，Galeorhinus galeus，短尾Carcharhinus brachyurus，灰六钩鱼Hexanchus griseus，Squatina sp.，Pristiophozus sp.，鳐科、蚤蝇科和泥鳅科。这是智利晚第三纪和南美洲其他地区最多样化的软骨鱼类组合之一。
Twelve taxa of chondrichthyan fossils from strata assigned to the Upper Pliocene of the Horcon Formation, Valparaiso region, central Chile, are described and prior records paleobiogeography and paleoenvironmental implications are discussed. The fauna includes Callorhinchus sp., Heterodontus sp., Carcharodon carcharias, Isurus oxyrinchus, Galeorhinus galeus, Carcharhinus brachyurus, Hexanchus griseus, Squatina sp., Pristiophozus sp., Rajidae, Dasyatidae and Myliobatidae. This is one of the most diverse chondrichthyan associations of the Late Neogene of Chile and the rest of South America.
