Amargospinus toy
Behavior: InGen's effort to create a ferocious carnivore with the size of a Brachiosaurus resulted in the massive Amargospinus. Standing over 40 feet tall, its long neck and tail provided a wide attack radius for its razor-sharp jaws, while its spiny back and slashing neck spikes offer a near-impenetrable defense. The Amargospinus is a loner by nature and second only to the Ultimasaurus for individual ferocity.
Trivia
