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 Argentine naturalist Galileo Juan Scaglia (1915–1989),[2] and the type species after Argentine 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]
