Content
Kryptobaatar were small jumping animals similar to modern jerboas [4] . Representatives of the genus were omnivores, in addition to plant foods, they also ate small reptiles .
The genus includes 4 extinct species:
- Kryptobaatar dashzevegi Kielan-Jaworowska, 1969 typus
- ? Kryptobaatar gobiensis [ syn. Gobibaatar parvus Kielan-Jaworowska, 1969 ]
- Kryptobaatar mandahuensis Smith et al. , 2001
- Kryptobaatar saichanensis (Kielan-Jaworowska & Dashzeveg, 1978) [syn. Tugrigbaatar saichaenensis (Kielan-Jaworowska & Dashzeveg, 1978) ]
In 2004, three other species were declared synonyms of the type species [5] .
