Pretty straightforward tame. Eats meat, so mutton's a great choice. Definitely want a trap with a ceiling. Only fits through behemoth gateways, or so is my experience. Mammal, so it has a gestation breeding timer and produces living offspring. Incredibly fast base speed, suggested to level Stamina for ultimate rocket power. Suggested stone trap.
I watched a video on this, thought I share. Watch nooblets for moré info. U can trap it with 2 small Dino gates. U place one, lead it into the doorway (so his head is stuck) then u can freeze it with an owl, get lose and place a second doorway a little bit past his head near his shoulders. Boom he can no longer move. (Hope this helps, if not watch his video😊 )
I recommend putting a regular dinosaur gate. to make the mangarm fit into one trap. then put another gate a little further than the wings. when you put the managarma to sleep, she will already be hungry. just give raw meat or lamb to tame. Personally, in 10 minutes I tamed the managa lvl 100 with meat, since she was already half hungry. I advise you to download stamina, health and punch.
