When raising Magmasaurs, you can incubate their eggs with either standing torches, dimetrodons (level melee only, it increases the incubation effect), air conditioners or a combination of all of the above. It takes a LOT of heat.

They eat Ambergris which can easily be mined from the lunar biome with an Anky (for the best yield).

Higher level Magmasaurs are best to raise, they have better food value.

At the β€œJuvenile” stage when they can be on trough, you can put their food (Ambergris) into a trough which helps with raising multiple tames (or bring over a character that has Tek unlocked and use a Tek Trough to preserve the food). (I play Xbox official).

Low level Mags might not look like they are taking food from the trough if their food value is low. Watch them and see if they eat once the value reaches zero. Higher levels do better for some reason. This knowledge might save someone some sleep. :-)
