Prime Rex and Kraken are the first Mythic-tier dinosaurs in My Dino Park. Both are sourced from the new Mythic Egg, which costs 500 Teeth and takes five minutes to incubate. Prime Rex rolls at 65% and Kraken at 35%.

The community trading market quickly priced Prime Rex at 10,000,000 trade points and Kraken at 15,000,000 trade points — the two most expensive assets in the game. YCE-adjusted, both clear the Kraken 1.5x Prime Rex baseline.

Players targeting the Mythic Egg should bank Teeth from the BESTDINOGAME and UPDATE2 codes before spending on the standard Teeth upgrade track, since the 500-Tooth price is the most significant Teeth sink in the current economy.
