This pattern includes three extinct predators that once prowled the ancient oceans:
Mosasaurus - This marine reptile hunted in the Late Cretaceous seas, around 82 to 66 million years ago.
Cameroceras - A distant relative of modern octopus and squids, this cephalopod was one of the top predators in the Ordovician ocean, around 486 to 443 million years ago.
Liopleurodon - An ambush ocean predator, this plesiosaur lived in the Late Jurassic, around 166 to 155 million years ago.

The 35 page pattern includes detailed step-by-step photos and clear written instructions to make three amigurumi-style Marine Monsters. PLUS there is a 10 page PRINTER-FRIENDLY TEXT ONLY VERSION at the end of the pattern. This pattern has been fully tested by multiple testers.
