Dinosauria has issues of its own. I tried running it by itself and had errors. I would recommend not using it in general and sticking to Jurassic dinos.

When making the initial version of my mod I used the same defnames as the one from dinosauria. I was new and didn't realise later on this hassle this would cause. I haven't changed the conflicting defnames though since these names are baked into the saves, so changing them would probably break a lot of saves.

You can try loading dinosauria below by mod, that may be able to fix it. Rimworld may load my mod defs before dinosauria and override them, so eggs should hatch with the intended pawn.
