What is Bronto worth?

Bronto's money value is $1.5M/s at base weight with no mutation, and its rarity score is 64 (available). A mutation multiplies that value, up to $5.25M/s with Rainbow (x3.5); several mutations add up, and a heavier Bronto is worth more.

Pets worth about the same: Radcoon ($2.2M/s), 67 ($1.55M/s), Crawler ($1.5M/s), Abyss Overlord ($1.25M/s).
