A good tank to use while taming is a carbonyem, now before you start asking why they are pretty tanky just pump health and stamina and maybe a bit of oxygen since you might need to be underwater awhile.
The wyvern is a lizard of the air,
To tame it's fury,
You must enter their burning lair,
It has three kinds: one's stormy one's toxic and one's fiery,
To enrage them is a deadly thought,
But if successful will not amount to nought,
If you find the glowing stone,
From Inside will come flesh and bone,
And lightning, venom, or fire,
But do not sink into the burning mire,
To get this treasure,
It does not bring pleasure,
It enjoys a nest of burning flame,
And milk of the beast from which it came,
But if you manage the impossible feat,
The wyverns's fury is now yours to tame,
If you hatch wings of thunder,
Your aim may often blunder,
But with its power,
It could topple the highest tower,
If you hatch wings of acid,
Your shot may miss,
But after that the air is no longer placid,
If you hatch wings of fire,
Your range is weak,
But your power is dire,
It happened just today, I just got level 55 and I immediately crafted a Tapejara Saddle, my Tapejara was patiently waiting for me to ride it since level 30+. My starter base was located near the red obelisk. My first flight with the Tapejara we encountered a High Level Quetz just above my base, hours passed and I tamed it with the Tapejara method, now the Quetz is patiently waiting for me to level up, so that I can ride him. I named him "Skull" cause of black body and white face.
6 pillars on top of each other. 6 ladders to get on top. Rex will aggro but won’t break pillars so just shoot tranqs from safety of the pillars. Should be easy tame for low level rex if you got the prime meat.
Attention fellow ark players, the tropeognathus is not only available on crystalisles it’s in on all maps! On the Island it’s in south east part of the map. Like so people can see this useful piece of information!
If you find this thing RUN it took me out in two hits and completely demolished my home and murdered my raptor and my little otter cuddles please like to pay respects to my little cuddles kept me warm on the cold nights
