This is probably the most simple way to tame these guys (on mobile ofc)

1. Spawn with a new character with a new name (that meets with a Griffin’s name)

2. Tame a BUNCH of lystrosaurus (preferably female for the eggs)

2.5. Name them Bob and Bobette (not necessary)

3. Once you know how to make a cooking pot, make some lystro kibble (cooked prime meat isn’t that hard to get just kill something slow and/or dumb like a sarco or diplo but be really quick and cool the meet ASAP before it spoils)

4. Use the lystro kibble to tame a male and female low-leveled diplodocus.

5. Now make some Diplo kibble (breed them for optimized production)

6. Use the diplo kibble for allosaurus. (Very hard and hope you have a crossbow, plenty of tranqs, soothing balms, spike walls to defend it when knocked, and a plan)

7. Mass produce allo kibble until Dododex fixes their kibble numbers.

8. Get x15 soothing balm from the amber shop. Find amber nodes or loot crates (allos are fast and strong so you can travel either by foot or on a saddle level 61 btw)

9. Find 2 low level griffins that respects you 1 male 1 female. Then trap and tame with allo kibble.

10. If too troublesome, just buy a chef station

11. Breed and level them up as you go if you want.
