FASA 365 Day 338, Plectrum Duplex Maxilla,
(Quilled Double Jaw Raptor) 150ft Carnivore
Double Jawed for breaking down and grinding up “armored” prey.
The more boney matter it eats the more plentiful the quills; processed by its body and manifested onto its head and spine.
This is a young specimen. As he ages and eats the quills will run down its back and tail.
