You say bograda and we currently have bagrada rex in game. Is it a new dino that expands the breeding log or is it a typo lots of places and its actually just bagrada we already have?
I typo'd (and have now corrected) that. I habitually wrote 'bograda' due to working on this update a couple months (for reasons highlighted by Benbored94).
The 5 variants of bagrada rex (including a rename with the original model) are indeed experimental off-breeds of the bagrada rex, with the bograda rex as the ultimate dino-mighty poop-tastic outcome.
Also as Benbored94 speculated, they're exclusive to this skilling area and don't feed back into the Player Owned Farm breeding log. They're produced through Firemaking/Fletching rather than Farming (for reasons which'll hopefully make sense in context tomorrow).
