Stratigraphy
Formation:Santa Cruz
Stratigraphic resolution:formation
Stratigraphy comments: Fernández et al. 2019: Ameghino (1900–1902) highlighted Pa. palmidens as one of the exclusive species of his ‘Notohippidian stage,’ which is currently regarded as representing a chronologically early local fauna of the Santacrucian SALMA (Marshall and Pascual, 1977; Marshall et al., 1983; Cuitiño et al., 2016). There are no precise stratigraphic data for the holotype of Pa. palmidens. Therefore, it is not possible to know confidently whether it was collected from above or below the tuff dated to 17.36 Ma by Cuitiño et al. (2016) in Río Bote.

Kay & Perry 2019: Collected from SCF at Río Bote above tuff RSC-27, dated at 17.36 Ma (Cuitiño et al., 2016).

Collection methods and comments
Reason for describing collection:paleoecologic analysis
Collectors:C. Ameghino
Collection method comments: Hernández del Pino 2019: Specimen MPM-PV 18806 was collected in situ in the lower 25 m of the Santa Cruz Formation at the Río Bote section. The specimen MPM-PV 18807 was collected from float at the base of the same section. The final repository for the studied material is the vertebrate paleontology collection of the MPM, in Río Gallegos City, Santa Cruz Province, Argentina. The specimens analyzed are detailed in Systematic Paleontology.
