Kryptobaatar,[1] also known as Gobibaatar[1] or Tugrigbaatar,[2] is an extinct mammalian genus dating from the Upper Cretaceous Period and identified in Central Asia.

The generic name Kryptobaatar is derived from Greek κρυπτός: kruptós, "hidden," (alludes to the ventral position of infraorbital foramen) and Mongolian баатар: baatar, "hero" (alludes to the name of the capital of Mongolia, Ulan Baatar).

The derivation of its synonym Gobibaatar parvus is Gobi (occurring in the Gobi Desert, Mongolia) and baatar ("a hero", the same as Kryptobaatar).

[1] Another synonym Tugrigbaatar saichanensis is a generic name derived from the Toogreeg and Ulan Baatar, and a specific name derived from a Gurvan Saykhan mountain range.

[3] Kryptobaatar was a hopping species, similar to a modern Jerboa.
