Megachelon Eggs are randomly dropped by Megachelons. They can be eaten or used to make Exceptional Kibble for taming Basilosaurus, Brontosaurus, Giganotosaurus, Karkinos, Managarmr, Mosasaurus, Quetzal, Rex, Spino, Therizinosaur, and Tropeognathus.
The Megachelon Egg takes 4h 59m 58.56s to hatch. It must be in the temperature range of -75 to 75 °C / -103 to 167 °F to successfully hatch, otherwise it will start to lose Health. The female Megachelon needs between 18h and 2d before having the capacity to lay eggs again. The incubation time can be reduced by up to 20% if the egg is placed in an Egg Incubator at the ideal temperature.
