- To tame an Amargasaurus, you must first sync your temperament with it. After syncing, you must hunt with it by attacking other creatures with it nearby. It will occasionally ask for
Exceptional Kibble. The Amargasaurus' taming meter increases with the amount of damage you inflict on nearby creatures.
Holding it still
Chain BolaFired from a Ballista or 
Harpoon Launcher. Grounds flyers and pins them where they land.
Large Bear TrapSame idea as the 
Bear Trap, sized for the big stuff. Bait it into walking over one.That's the full list — nothing else immobilizes a Amargasaurus, per the game's own immobilizer table (drag weight 375).

Abilities
what it does and how you trigger it 
- Melee Attack Primary attack
The Amargasaurus has 4 different melee attacks, with left/right variants, all dependent on movement and camera direction. Bite: Deals 40 base damage. Least damaging attack, but is only used when sprinting. Gore: the Amargasaurus gores opponents with its neck. Deals 46 base damage, and is used while walking or standing still with the camera faced forward. This is the only melee attack that afflicts status effects dependent on the current Spike Mode. Tail
Whip: The Amargasaurus whips its long tail to one side behind it, depending on the direction the camera is facing while backwards. Deals 50 base damage. Has a large area of effect, making it useful against groups of creatures. Stomp: The Amargasaurus stomps with its frontal left or right foot based on the direction the camera is facing while looking downwards. Deals 55 damage in a small area. Only used while standing still or walking.5 stamina - Cycle Spikes Special 1
Cycles the current Spike Mode of the Amargasaurus, with 3 different modes to choose from: Armor Spikes, Heat Spikes, and Cold Spikes. The status effects applied by Amargasaurus spikes do not affect Bosses or Titans. Armor Spikes: Afflicts a percentage-based debuff called Armor Reduction, which grows stronger depending on how many times the target is hit by the debuff per tick, and causes the target to take increased damage from all sources; up to 25% and reduces its armor value in relation with the percentage of the effect down to its default value (Just if the armor or saddle has quality). Heat Spikes: Afflicts a percentage-based debuff called Igniting, which deals moderate damage over time. If Igniting reaches 100%, the Enflamed debuff does 75 damage per second and will be continuously applied until hte target get out of the spike's aura, then it will last for 10 seconds. Cold Spikes: Afflicts a percentage-based variant of the Frozen debuff, which deals no damage, but progressively slows the target. If this debuff reaches 100%, the Frozen debuff is applied for a short duration, locking all movement and preventing attacks. This effect also gives 6 seconds of Freeze Immunity effect after the target releases from the frozen. This move IS technically an attack as well; hitting opponents in melee range and doing a hefty 70 base damage, technically making it the Amargasaurus's strongest attack, at the cost of being abysmally slow.
20 stamina · 3.5s cooldown - Take Aim Secondary attack
Holding this button enables the aiming mode for firing spikes. Firing the spikes themselves is done by using the primary attack buttons. Spikes that are fired will travel in an arc rather than a relatively straight line like an arrow or bullet, which can make precise aiming at long distances difficult. The spikes generally travel further the higher the cursor is aimed. When spikes land, they will begin to emit an AoE charged with whatever Spike Mode the Amargasaurus was in when it fired, and will apply the status effects of said Spike Mode. These spikes count as Structures when they land, and will slowly degrade, indicated by a sinking animation, until they break or are refreshed by another spike landing in the same location. When the spike breaks, the AoE it applies will also disappear. The spikes will not land on certain harvestable environmental structures like rocks, and will instead bounce off and around until they either hit solid ground or disappear.
- Fixed Movement Jump
Locks the Amargasaurus into walking in a straight line, designed to help fire spikes with accuracy while moving. Can be toggled on and off.
Passive
The Amargasaurus naturally regenerates 
Amargasaurus Spikes after it uses or lost one, the regeneration time seems to be around ~8 seconds per spike, using this numbers if the Amarga loses all its 20 spikes it will need to wait a total time of 160 seconds (or 2:40 minutes) to regenerate them all.
To retrieve an Amargasaurus Spike use the radial wheel, once retrieved it can be used to craft the 
Amargasaurus Saddle or to increase the production speed of 
Sap by placing it inside a 
Tree Sap Tap.
Similar to the 
Basilosaurus, riding the Amargasaurus provides the player with the Insulation buff, massively increasing the player's Hypothermic and Hyperthermic insulation.
