Temporal range: Late Cretaceous, 75Ma
Description and history
Cherminotus is small for a monitor lizard and has a longer snout than its closest relative, the living Earless monitor lizard. Cherminotus is also very similar in appearance to Aiolosaurus, another monitor from the Cretaceous of Mongolia. Both monitors have a single hole in the lacrimal bone called the lacrimal foramen. Other monitors and monitor ancestors have two holes in the lacrimal, making the presence of only one hole in Cherminotus a case of evolutionary reversal.
