An Amargasaurus is read from its neck first — that double row of tall, sail-like neural spines down the back of the neck is the whole silhouette, and a model that gets them wrong reads as a generic sauropod. This one carries the full spine row as a single sculpt on the same frame and movement system as the rest of the range, so the neck reads correctly from fifty metres and still holds detail up close.

The neck spines are where the budget goes, and it shows. Each spine is moulded and finished by hand, and the animal is built to the size and the site it is going into rather than pulled from a standard.
Two rows of tall neural spines rise off the neck and shoulders, forming the sail that makes an Amargasaurus unmistakable. They are not stuck-on fins — each spine is part of the sculpted back line, tapered and finished so the curve reads at a distance and the edges stay crisp in person. The spacing and height are set against reference, not guessed.
Below the spines the body is a short-necked sauropod: a heavy four-legged frame, a long counterbalancing tail and a small head on a neck that lifts rather than stretches. An Amargasaurus built with a too-long neck or a flat back reads as the wrong animal, so the proportions here follow the skeleton, not the display habit.
This is an outdoor animal. The frame is hot-dip galvanised steel, the skin is anti-UV composite silicone over an elastic fibre mesh, and the servo drive is rated to IP65, so it runs through a wet season without the paint going chalky or the joints seizing. Colour is laid down in multiple gradient layers under a UV topcoat, which keeps the spine sails reading as bone and sail rather than as grey plastic after a summer outside.
The unit arrives in bolted sections and assembles on site without welding. The spines are the fragile part, which is exactly why they ship as protected modules and bolt on last — the section that breaks in transit is the section that is easiest to replace.
Park entrances, museum grounds, themed streets and mall atriums. The neck sail is legible from a long way off, so it works as a landmark in a landscape and as a character in a themed area. It is supplied with the dinosaur information board as a separate element — the display works harder when the animal and its interpretation arrive together.
What sizes can be built? Anything from 1 m to 30 m long and up to 15 m tall. The size is set by the site, the sight lines and the transport route, not by a fixed catalogue.
How is it triggered? Four ways: infrared or radar sensing, a pre-programmed sequence set before dispatch, handheld remote, or voice interaction. Most sites run the sensor as the default and keep the remote for staff.
What does it need on site? A 110 V or 220 V supply and a solid fixing point. The unit arrives in modules and bolts together — no on-site welding.
Can it run outdoors? Yes. The standard specification is an outdoor one, with anti-UV silicone skin, a water-resistant servo drive rated to IP65, and a hot-dip galvanised frame that tolerates salt spray.
How is it fixed? Four options: concrete foundation with pre-embedded anchor bolts, a weighted base that can be moved as one piece, expansion bolts on a hard indoor floor, or a sealed and buoyancy-rated base for water features.
How long does production take? Custom builds run on a lead time confirmed against the drawing. Send the requirement and the site plan, and the proposal comes back with the timing and the drawings marked up.
Materials. National-standard steel frame, first-tier servo motors, high-density foam core, composite silicone skin over elastic fibre mesh, hand-sprayed colour finish.

The model ships in modules on a reinforced timber crate, with the frame sections, skin panels, spine modules and hardware packed and labelled for assembly. Nothing on site is welded; the sections bolt together and the base is fixed to a concrete foundation, a weighted base or expansion bolts depending on the surface.
Assembly is a two-day job for a crew, and our technician joins the first run so the movement settings are dialled against the actual ground and light. The spine modules are checked in place last, because a spine that has shifted in transit is a quick fix on day one and a return visit if it is not.
The information board, the lighting and the surrounding landscape are quoted separately and can be drawn at the same time, so the animal and its interpretation arrive as one project rather than two.
