Tamed a 145 on official 1x rates. The Ceratosaurus sobers up at around 54% taming progress. So you have to get it drunk again.

Used 8 cocktail and 19 kibble.

Fly to Carno Island and kill every cerato you see. Imprint the Babys and thats it. No taming and preparing. Kill everything on Carno and new Dinos will spawn. I now have 5 juvenile Cerato including male and female. Took me 30 mlnites

Just tamed a lv 145 without issue on 4.5x small tribes

1) Get a Rock Elemental and decent saddle

2) 3 hemoglobin mixtures

3) 7 extraordinary kibble.

4) Find your target and get Rock Golem there

5) Kill everything else in area first then feed hemoglobin mixture to Golem and punch Cera once.

6) Feed Golem again when mixture runs out

7) Feed Kibble passively

Congratulations you have a Ceratosaurus

Spread the word

150 F cerato took 8 hemoglobins and 20 extraordinary kibble on 1X to tame. Took 4 to get it drunk.

Was able to claim some baby ones on Carno island just had to eliminate the parents

Tamed a 150 with 2x rates took about 29 prime meat used a rockgolem with a good saddle and drunker it out three times

You need 4-5 hemoglobin to get it drunk once.(2 times at least to fully tame it)

Use a stego with hard plates and decent saddle.

Prime meat is 6% on 3x rates. Exceptional kibble 16%

Used one kibble and prime meat to get it to 57% until it became sober again.

For prime meat the interval is 1 min.

They spawn all over scorched earth, super easy to farm venom there

Haven't seen anyone recommend this. Bring Cakes or Meat. You can mitigate about 1/3 or more if damage by constantly feeding.

My thyla with 8k hp and a primitive saddle was about to get a 150 drunk.

If you are playing ASA then all you have to do is go looking for ceratos, find one with babies, slaughter the parents, and imprint on the ceratos (I recommend killing with thylacoleo.
