Tip : Don't put wooden / metal spike walls near your base if you live in an area with a lot of sauropods.
this is why : since they like to wander around, There's a chance that they will get stabbed by the spikes when they wander near your base. And they will get mad at you, kill your tames, and wreck your base.
so please be careful and think twice before setting up spikes near your base.
Whoever it was who said one pushed them off a cliff for no reason. That was a diplodocus not a bronto diplodocus are small and have straight necks and pointy teeth for stripping leaves off of bushes and ferns while brontos are big with bendy necks and kind of beak like mouths for snapping leaves and twigs put of the canopy.
