Jurassic Mosasaurus guide
Jurassic Mosasaurus is a marine reptile from Jurassic Island that you can no longer fish up: it is flagged Unobtainable. What it leaves behind is a set of numbers that explain why it is still talked about.
Its size is the headline. A typical Jurassic Mosasaurus weighed 9,500 kg, with a minimum of 4,000 kg and a maximum of 31,500 kg. That maximum is 68th of 663 fish by weight, one of the heaviest on record. It sold for an average of C$9,500, 130th of the 742 documented fish by average value, and gave 30,000 base XP. The price per kg was only C$1, so the money came entirely from mass.
In the same zone, Edestus, Jurassic Helicoprion, Oreochima and Rhizodus shared its Limited rarity, and the Mission Specialist's Rod was sold there. Compared with its neighbors, the Mosasaurus was the biggest and the most rewarding in XP. For anyone who owns one or sees it in a trade, the value is mostly sentimental plus the reference price: about C$9,500 on the sale side, far above the typical documented fish. No live way exists to farm it, so its worth rests on scarcity.
