About Alcidedorbignya
Alcidedorbignya is an extinct pantodont mammal known from the Early Paleocene (Tiupampan SALMA, 65.5 to 61.7 million years ago) Santa Lucia Formation (18.0°S 65.6°W / -18.0; -65.6, paleocoordinates 20.7°S 52.5°W / -20.7; -52.5) at Tiupampa near Mizque, Cochabamba, Bolivia.
Following a naming convention established by pioneering Argentine palaeontologist Florentino Ameghino (i.e. combining the first name and surname of a prominent scientist), the genus name honours French naturalist Alcide d'Orbigny.
