Pachycephalosaurus sapiens is a species of bipedal social and sapient omnivorous pachycephalosaurid dinosaur that originally filled the ecological role and similar behavior to early human species. It first lived during the Late Cretaceous Period (Maastrichtian stage) of what is now North America, however, thanks to SciiFii, they have been brought back from extinction as several subspecies, ranging from completely scaly, to being partially feathered, to fully feathered. They are generally peaceful species and they have their own forms of cultures, religions, societies, languages, technologies, etc, but can learn human forms of cultures, religions, societies, languages, technologies, etc extremely well. They can make, manipulate, and use stone tools and other forms of weapons and technologies (including modern ones like computers, etc) with their front limbs or hind limbs, depending on a subspecies or an individual of that subspecies. The real life existence of genera Stygimoloch and Dracorex is doubtful due to some Pachycephalosaurus sapiens being born with some conditions and/or genetic diseases causing their heads to resemble that of the supposed Stygimoloch and Dracorex.
