Extinct genus of amphibians
Kokartus is an extinct
genus of prehistoric
stem-group
salamander (
Caudata ) from the Middle Jurassic
Balabansai Formation of
Kyrgyzstan .
[1]
The absence of clear lines of arrested growth and annuli in long bones suggests that the animals lived in an environment with stable local conditions.
[2] Like other members of
Karauridae , it is thought to have been
neotenic .
[3] Kokartus is thought to have fed using
suction feeding via the enlargement of the
buccal cavity on small fish and invertebrates, with the well developed palatal dentition (teeth on the roof of the mouth) and marginal teeth helping to grasp prey.
