How did Sauropods protect themselves against lightning

[Count Iblis]

These huge animals must have been very vulnerable to being hit by lightning. Also, I think that in the Jurassic the climate was warmer and there were more thunderstorms.

This gives you an idea of the number of lightning hits per hectare per year

Note that large parts of the land receive very little lightning. Note Central Africa has the highest frequency of lightning hits.

Sauropod dinosaurs made a living eating leaves from higher branches of trees, analagous to giraffes today. Tress that were/are taller than the animals themselves. Giraffes occur in the area of the map that has extreme lightning frequency.

I would suggest that whatever behavior giraffes exhibit during a lightning event is adaptive. Consider using that as a model for guessing the behavior of sauropods.
