Mosasaurus

Where to catch the Mosasaurus

The Mosasaurus lives in Deep Waters (zone 10 of 17), around the middle of the zone. It is number 5 of 7 in the Deep Waters index. A full-strength throw needs roughly 1,850 – 2,150 Throw Power to land in Deep Waters.

Foods that land here: Golden Apple ($120Qa), Crystal Melon, Ember Lemon. A higher-tier food pushes the roll toward the rarer end of the Deep Waters list, so the newest food you own is always the best bait.

Any throw that lands around the middle of the zone can produce it. If you are hunting it for the index, lower your throw strength with the gear icon until the food lands on that spot – distance inside a zone decides which animals can come.

Is it worth keeping?

• A plain Mosasaurus earns 21x a plain Velociraptor, the best animal from Prehistoric Forest.
• The first animal in Hell, the Gargoyle, makes 9.7x as much – once your throws reach Hell, replace it.
• Keep it longer only if it rolled a strong mutation or size (see the table below) or you need it for the index.

Mosasaurus income by mutation and size

A plain Mosasaurus makes $3.1Qa/s. Mutations and sizes multiply that number, and the two stack. The table below multiplies the plain income by the multipliers I have measured (Gold ×1.5, Diamond ×3, Emerald ×5, Ruby ×10, Rainbow ×20; Big ×2, Large ≈×4.3, Huge ≈×9, Colossal ≈×18.5, Gigantic ≈×37). Treat the size columns as estimates – real catches land a little above or below. With the 2x Cash gamepass every number doubles.
