Ferrucutus

Ferrucutus is a fictional species of dinosaur that appears in the 2005 Universal Pictures film, King Kong. Ferructus were tank-like ceratopsians with highly ornate bony crests and broad shoulders. These aspects, coupled with their aggressive behavior made them difficult prey for most predators. The size of their frill indicated the individual Ferrucutus' seniority. They grew over time, but males sported the most impressive arrays, with horns growing up to lengths of six feet. In sexually mature males, the coloration of the frills changed color to indicate readiness to mate. As crests developed, secondary horns atop the crests could grow to cross over one another, although this was rarely seen in females. Because of this, the level of horn crossover could be used to indicate an individual's age.
