Sauce town (Pliocene to of Uruguay)

Where: Canelones, Uruguay (34.6° S, 56.1° W: paleocoordinates 34.7° S, 55.2° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Raigón Formation, Pliocene to Pliocene (5.3 - 0.1 Ma)

• Raigón? Formation (Pliocene to early Pleistocene). Assignation to this unit is doubtful

•because it comes from a drill core.

•This collection had a Pliocene-E. Pleistocene age assigned. However, According to the most recent stratigraphic proposal (Bossi et al., 2009), the Raigón Formation comprises two members: the lower, and certainly the most fossiliferous, San José Member, and the upper, San Bautista Member, which has very few fossils. The lithology and facies analysis of the Formation enable us to propose a deposition in transitional and fluvial environments, with aeolian episodes, which are sometimes predominant (Perea and Martínez, 2004; Bossi et al., 2009).

•This Formation has been traditionally considered a Pliocene unit, but the mammalian content suggests a Pliocene-middle Pleistocene age (Perea et al. 2013). Optically Stimulated Luminescence ages of 373 and 218 ka for the top of the sequence indicate a middle Pleistocene age (Ubilla and Martínez 2016). The sedimentary beds of this unit could have developed under a seasonally humid climate (Tófalo et al. 2009) or arid to semi/arid condition (Bossi et al. 2009; Panario et al. 2014).

• formation-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; green claystone and sandstone

• the remains were collected from a green clay facies interleaved with sandy facies that are characteristic of the Raigón Formation, caution is taken to assign it to this unit because the remains were found in a drill core.

Size class: macrofossils

Collection methods: the remains were found in a drill core.
