A Triassic common ancestor of the T-Rex and Triceratops. This two-fingered variant transitions from a scaly juvenile to a smooth-skinned adult. Its mid-life smooth phase is the 'Triceratops' stage (German: Dreihörnglatthaut). They died out after evolving into their famous descendants. Their oversized arms and frilled heads provided the genetic blueprint for later species. In their prime, their skin was as smooth as silk, a stark contrast to their rugged youth.An ancestral meat-eater with three fingers. Following the Saura-Vatra life cycle, it matures from a scaly youth into a smooth-skinned 'Rex' stage (Colombian: Rey-Liso). These species vanished in the late Triassic as their biology evolved toward the Cretaceous giants. They were more agile than their ancestors, using their three fingers to climb and hunt. The smooth-skin phase marked the pinnacle of their predatory efficiency.The tiny peaceful ancestor. Even this hand-sized species shared the Triassic timeline: starting with scales and shedding them for smooth skin in its prime. It represents the shared evolutionary root before the group evolved into the Rex and Triceratops lineages. Micros-Eirene scavenged the undergrowth, its smooth-skinned phase allowing it to glide through vegetation with ease, avoiding the 'Evil Lizards' that stalked the Triassic marshes.
