Frequently Asked Questions:
1. Are the 1.18.2 and 1.19 versions the same? Yes! It doesn't matter which version you play on since they both have all the same features!
2. Why are there no spawn eggs? In order to spawn in a dinosaur, you must use the hatched eggs.
3. Why do the dinosaurs always spawn as babies? In order to forcefully grow a dinosaur into an adult, you must use a miracle berry, which as of now, is a creative mode only item! If your playing in survival, you will have to wait until they grow on their own.
4. Will the mod get a 1.16.5 port? No, the oldest version we'll be supporting as of right now is 1.18.2, sorry for the inconvenience.
