Stratigraphy
Formation:Santa Lucía
Stratigraphic resolution:group of beds
Stratigraphy comments: said to be 125 m above base of El Molino Formation at Tiupampa and Maastrichtian (Marshall et al. 1983) but actually from "between 110 and 140 m above the base of the Santa Lucia Formation" (Muizon and Marshall 1992)
"The Tiupampa mammals occur in the middle section of the Santa Lucia Formation (Marshall et al. 1997). This section has been referred to the early Palaeocene by Gayet et al. (1992), Bonaparte et al. (1993), and Muizon (1998). However, an early late Palaeocene age has been suggested by Marshall et al. (1997) and Pascual & Ortiz-Jaureguizar (2007). Recently, Gelfo et al. (2009) have reassessed the age of the Tiupampa mammal fauna and concluded that it is of early Palaeocene age. The Tiupampa mammal-bearing beds are regarded by these authors as a probable equivalent of the late Puercan (Pu3) of North America and would therefore be as old as 64 to 64.5 Ma. This hypothesis is based on the fact that the Tiupampa mammal-bearing beds are included in a single reversed stratigraphic series, which is likely to correspond to Chron 28r (see Gelfo et al. 2009 for discussion). However, when Gelfo et al. (2009) wrote their paper, the reference for calibration of Chron 28r was Lofgren et al. (2004), and the correlation was with the late Puercan (Pu3). New dates and calibration of the NALMAs have slightly modified the age and position of Chron 28r. According to Wilson (2013, 2014) and Sprain et al. (2014) Chron 28r is totally included in the base of the early Torrejonian (To1) and its absolute age is bracketed between c. 65 Ma and 64.866. This represents the very base of the early Torrejonian (To1), which spans from 65.118 Ma to c. 63.5 Ma. In other words, the absolute age for the Tiupampa fauna is c. 65 Ma." (Muizon et al. 2015)
