Abstract
The paleontological site “Picos II”, located at Picos farm, municipality of Piranhas, is a fossiliferous deposit with lagoon geomorphological features. The material found was in excellent condition, two Pleistocene mammalian taxa were identified: Eremotherium laurillardi and Notiomastodon platensis. The taphonomic analysis indicates that the deposited material suffered short transportation, in high-energy environment, taking form as a single depositional event covering the crystalline basement level, with disarticulation in situ, which explains the high degree of conservation of the material. The sedimentological analysis corroborates the information obtained in taphonomic analysis. The well preserved material found in SP Picos II demonstrates the great potencial of the lagoon type deposits, with less steep lateral than tanks, and promotes a smoother transport and accommodation of skeletal elements.
