Scaglia is an extinct genus of South American astrapotherid land mammal that lived during the Eocene (Casamayoran to Divisaderan in the SALMA classification). ^[1] The genus is monotypic, with its only known species (and thus its type species) being Scaglia kraglievichorum.

Etymology

The genus was named after Argentinian naturalist Galileo Juan Scaglia (1915–1989), ^[2] and the type species after Argentinian palaeontologist Lucas Kraglievich (1886–1932).

Description

Its type specimen, recovered from the Sarmiento Formation of Argentina, is MMCNT-MdP 207. ^[3] Like Albertogaudrya , Scaglia was the size of a sheep or a small tapir, hence among the larger mammals in South America at that time. ^[4]
