Castorides are an really strong dinosaur type , i love them , today i found a 145 lvl (i play on medium) and i knocked it out, heres how:

I had 1 bola and an ascendant bow with 20 tranq arrows,

Step 1 : run and get free hits (just to make sure it doesnt run after the bola)

Step 2 : bola it

Step 3 : Shoot it until it goes down it took 8 arrows for my ascendant bow with 284 damage.

Ok so i made a mistake i should have made kibble and got a soothing balm but i dont have a raptor for a cave or i dont have a gallimimus soooo yeah i gotta wait 3 hours for this thing (1.2% with 100% taming effectiveness and carrots..) Basically when you want to tame an castorides

Dont forget,

Kibble ( if its an high level )

Soothing balm ( if its an high level )

Bio Toxin/Narcotic/Narco Berries (I got around 70 biotoxic 80 narcotic and 1200 narcoberries for my own castorides and i had to use all)

Oh and if you dont have a ascendant bow/rifle use a longneck with darts it takes around 20 darts for 150
