Two species – do we know?
"It contains two species, A. mongoliensis and A. crassum. It was formerly placed in the families Mesonychidae or Arctocyonidae,"

Do we really know there were only two species, or do the authors mean that two species are known? Usually, only a tiny fraction of the animals are fossilised (though relatively more large mammals than e.g. insects, of course), and far from all fossils are discovered.

Second species name
The second species may originally have been named as A. “crassum,” but ICZN rules prescribe that the correct name is A. crassus, matching the masculine gender of the genus name Andrewsarchus. N. Pharris (talk) 00:52, 7 January 2024 (UTC)
