The Argentinosaurus can be found by large forest areas which include redwood biomes. To tame one as your own you will need to tranq it out until it’s down, however the argentinosaurus can take up alot of tranqs until it will go down so make sure you got enough with you if you trying to tame one of these enormous beasts.
Once tamed you will need to make a saddle inable to ride them. The saddle consists of two platforms on its sides and the main rider in the middle which is good for organising where to put cannons ballista or even storage and crafting structures
In order to make the saddle you will need
150 silica pearls
200 metal ingots
550 hide
600 fibre
30 wood
but once you made its saddle you can turn your Argentinosaurus into a Titan of war.
the Argentinosaurus has three different attacks
1. a regular stomp attack
2. Knock back tail whip
3. A charge up stomp (when for 20 seconds the Argentino can stand on its hind legs and when stomped it can be very messy it can destroy structure up to metal but not tek structures
its a very tanky Dino able to take 10% less damage against turrets and for harvesting it can only gather berries and stone.
If you have a male and female Argentinosaurus you can breed them but the raising will have the same time as a rhyniognatha and will require berries to keep it alive and they can be put into a meawing for raiding but not a procoptodon
the only downside is its speed since it only runs slightly faster than a bronto and it also has quite low stamina too since it is a large creature, but don’t worry the Argentinosaurus will surely have a great amount of weight and health and decent damage which can help you travel around and soon you will surely be able to rule the ark with these powerful giants.
