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]
