Captures the features of the early Jurassic theropod—slender, agile body covered in textured, pebbled skin (earthy tan base with vivid red-pink frill gradients, as seen in the image), long, muscular hindlimbs built for quick, nimble sprints, and a thin, balancing tail for rapid directional shifts. Its iconic, twin bony crests on the skull (elongated and blade-like, a key species trait) are meticulously replicated, along with small, three-clawed forelimbs, narrow snout lined with sharp, conical teeth (adapted for hunting small prey), and alert, forward-facing eyes. The expandable neck frill (a defining feature) is recreated to flare open dramatically, exuding a fierce, defensive "early Jurassic predator" vibe that reflects its carnivorous nature in prehistoric North American woodlands and river basins.

Equipped with a drive system for dynamic head swings (left and right, up and down), jaw opening/closing synchronized with high-pitched hisses and shrill roars (mimicking territorial warnings and predatory calls), and flexible tail flicks (side to side). The signature neck frill can expand and contract smoothly (a defensive display behavior), while the slender forelimbs twitch and grasp (simulating prey-catching motions). The torso shifts subtly to suggest the lightweight, quick gait of a small theropod patrolling its habitat. Movements are fluid with no abrupt transitions. Can be fixed on a simulated Jurassic forest floor or rocky riverbank base (or ground bracket) to enhance the "ancient North American predator" scene.

Adjustable size (fitting park/museum spaces), skin texture (rough pebbled scales or smooth leathery finish), color (matching theme areas—e.g., moss green with orange frill for forest settings, desert beige with purple frill for arid landscapes), and movement modes ("static display with frill closed" or "high-dynamic motions like frill flaring and hissing"). Supports adding interactive sensors (frill expanding and aggressive hissing when visitors approach) or installing a safe viewing barrier nearby (for guests to "encounter the Jurassic crested predator" through observation and snapshots).

Frame made of lightweight alloy (easy to install and stable), body skin of weather-resistant silicone (scratch-proof, UV-resistant). All moving joints are buffered with no sharp edges. Electronic components are dustproof (and moisture-resistant for outdoor use), adapting to varied park environments. Daily maintenance involves surface cleaning and line checks, suitable for high-traffic parks, museums, and theme parks.
