150 ptera can easily become another friend from your dino family, just use a crossbow (or a bow,but you will need a bola.) in it's head, it will sleep with 1 shoot, feed with meat, recommended a soothing balm(bad at english,I'm actually from Ecua),Prime Meat or Dodo kibble

Once tamed, enjoy your ptera (mobile tip)
