If you encounter one of these guys, trust me anything can kill them. Even just a dodo! The reason for this is because Diplocodus has only one attack, that’s a knock back. It won’t even hurt you unless it throws you off a cliff. Would not recommend taming, it is useless unless you plan to use it as bait for big carnivores. Kill Diplocodus for raw prime. Best source for prime because it is defenseless.
