Name: Erlikosaurus ‭(‬Erlik's lizard‭)‬.
Phonetic: Er-lick-o-sore-us.
Named By: Altangerel Perle‭ ‬-‭ ‬1980.‭
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Saurischia,‭ ‬Theropoda,‭ ‬Therizinosauridae.
Species: E.‭ ‬andrewsi‭ (‬type‭)‬.
Diet: Herbivore.
Size: Skull about 25 centimetres long. Body size uncertain due to lack of remains, but roughly estimated to be about 3.4 meters long.
Known locations: Mongolia‭ ‬-‭ ‬Bayan Shireh Formation.
Time period: Cenomanian to Santonian of the Cretaceous.
Fossil representation: Almost complete skull with mandible‭ (‬lower jaw‭) ‬and partial post cranial remains.

       Named after Erlik,‭ ‬the demon king in Mongolian mythology,‭ ‬Erlikosaurus was a ground breaking discovery as it was the first therizinosaurid skull known to science.‭ ‬Despite the overall lack of other skeletal material,‭ ‬this skull made Erlikosaurus a model for other therizinosaurids,‭ ‬which at the time were only known from their post cranial remains,‭ ‬to be based on.‭ ‬That has worked both ways however,‭ ‬with post cranial material from other therizinosaurids filling in for Erlikosaurus's missing skeleton.‭ ‬Erlikosaurus has a particularly strong association with the related Segnosaurus from the same fossil formation.
