Also known as LHBL
Where: San Juan, Argentina (32.0° S, 69.8° W: paleocoordinates 32.6° S, 65.2° W)
• coordinate stated in text
• small collection-level geographic resolution
When: TC3 Member (Chinches Formation), Santacrucian (17.5 - 16.3 Ma)
• This is a level coming from the lowest third of the Chinches Formation
•(Manantiales basin).
•The Tertiary sequences in the Manantiales basin represented by the Chinches Formation, have been divided into seven members (TC0 to TC6), and their integration allowed a reconstruction of the development over the whole Manantiales basin (Pérez 2001a) (Fig. 2).
•The Las Hornillas bearing level corresponds to TC3.
• group of beds-level stratigraphic resolution
Environment/lithology: fluvial; massive, lenticular, coarse-grained, conglomeratic sandstone
Size classes: macrofossils, mesofossils
