Nemegtosaurus skull



This is a reconstruction of the skull of Nemegtosaurus mongoliensis based primarily on the original description of Aleksander Nowinski, but supplemented by the re-description by Jeffrey A. Wilson as well as the description of the new nemegtosaurid Tapuiasaurus. My interpretation is a bit different than portrayed by these authors.

The grayed-out parts of the skull indicate material that was not preserved.

This is a question, not a critique: do you think sauropods had cheeks at all? Your reconstruction seems to show them. Since that would be an important thing to try and get correct in a painting, I'd like to know your thoughts.

And was the lower jaw so undershot as you've shown? Just asking; I've no way of knowing, since nemegtosaurs aren't sold in my grocery store...
