Tamed one in a trap *they don't fit through regular dinosaur gateways* it was level 1 so it was not the best spino tame but if you guys want the recipe it'd be:

16 stone foundation (spinos cannot damage stone)

8 tall stone walls *or 32 regular stone walls*

Place wall every other space, to gat a slotted trap with a foundation length space between each

Make 1 stone wall as short as a regular one

Lead through trap and enjoy tame!

*Lvl.1 spino requires about 10-15 tranq darts
