Etymology

The genus was named after Argentinian naturalist Galileo Juan Scaglia,[2] and the type species after Argentinian palaeontologist Lucas Kraglievich.

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]
