This is my favourite mod by ElCeejo. It's not even for the dinosaurs themselves, but the gameplay. Scouring your world for fossils, never being quite sure what you'll find, the fossils are rare enough that you'll never be overloaded with them, providing that extra bit of motivation to delve into yet another cavern (which Minetest badly needs). Often enough your fossils end up being duds, but even then, the bones and other materials you get can still be put to use.
When you do find something cool though, another level of fun begins. Now you have to set up a labratory and play John Hammond in Jurassic Park. Like the fossil hunting gives you a reason to immerse yourself in the world, this mechanic gives you a reason to build more rooms. That's all before you get to managing your own menagerie of living dinosaurs, with feeders and various other tools.
This mod is an underdog compared to Draconis, so PaleoTest might not see as many updates or fast fixes when issues emerge. There were some texture issues for some dinosaurs and depending on the texture pack you’re playing with, sometimes the stone texture of the fossils doesn’t blend in making them easier to find than they should be.
But the potential...
As some players have requested, there could be an option for wild spawning dinosaurs - this could be done by having a special lost valley biome that generates very rarely and is isolated from the rest of the world by mountains (ala Arthur Conan Doyle's ‘Lost World’. You could also go full 90's action figure and embrace adding craftable cockpits, turrets, catapults and all kinds of gadgets onto dinosaurs.
Small tweaks I'd like to see
I'd love more lab gadgets and optionally depending on an electricity/power mod, to give you more reasons to build infrastructure. Also, electric fences that require generators opens up room for sabotage!
