Mosasaurus?

[Rii]

I see the Mosasaurus DNA and Egg in the item list, but regardless of how many fossils I put through an analyzer, I cannot get a Mosasaurus DNA. I tried in creative mode by setting up a dozen or so analyzers and filled them with biofossils and sat there for far too long trying to see whether or not it was a rare find. So far the results are zilch on the Mosasaurus count. I tried taking a different approach to the problem by going to the tropicraft dimension - since all the dinosaurs seem to spawn there - to see if there was one there I could use an entity move on..

 

No such luck.

 

Tried to find villagers that might offer the trade. Nothing.

 

So, what am I doing wrong here?
