The House
A real Triceratops skull sold at Sotheby’s for $661,500. In July 2026, “Gus” — a Tyrannosaurus — sold for $50.1 million.
Those bones now sit behind glass in a freeport or a foundation, seen by almost no one. OSSA exists for the other possibility: the same museum specimens, cast to the millimetre in the atelier, hand-finished, and installed in your own space — the apex predator as the object a room is built around.
Every OSSA work is a cast — an anatomically exact reproduction of a documented specimen, never a real fossil, never removed from science. It is the honest, unrepentant way to own a dinosaur: no looting, no export dispute, no vault. Only the form, at the scale of the animal, under a single light.
Each is issued as a numbered edition and entered, by name, into the OSSA Register. What you commission is not décor. It is a work with a lineage — and a place that remembers your name.
— Daniel, OSSA
Why a cast
The bone belongs to science. The form can belong to you. A cast carries the exact anatomy of the real animal — the same skull, the same scale — without the vault, the guilt, or the eight-figure price.

The Folio
One specimen · seen in the rooms it is made for
Each work is presented on a designed pedestal, vitrine, or plinth — chosen for the specimen and the room, lit to a single dramatic source. The display is part of the commission, not an afterthought: it is what separates an installed OSSA work from a crated cast.
Founding Edition · No. 001
Tyrannosaurus rex
Skull · Edition of 25Every specimen carries its story in four acts — the animal, its death and finding, its raising in the atelier, and its keeper. This is the shape of the dossier that ships with the work.
I
The Animal
The most complete predator the fossil record has surrendered — a Late Cretaceous tyrant, dead some 66 million years, the skull alone the length of a man.
II
The Death & the Finding
The provenance of the source specimen: its formation, its locality, the institution that holds the original. Cited by catalogue number — never implied as your own.
III
The Raising
Cast to the millimetre, hand-finished in the OSSA bone patina over documented hours, mounted, and set on its chosen pedestal under a single light.
IV
The Keeper
A blank page, signed in ink at installation. Your name, your number in the Register — the moment the work passes into your custody.

How it is done
The Commission
It begins with a render, not a price1
See it in your room, first
Send one photograph of the wall or corner you would consider. We render the specimen, life-size, in your actual space — at no cost and no obligation. You see it in the room before anything is made.
2
Choose the specimen & its display
The species, the form, and the pedestal, vitrine, or plinth it is presented on — walnut or blackened steel, floor or wall. We hold your number in the edition while you decide.
3
The Raising
The work is cast, hand-finished, and mounted over the commission period, documented as it goes. A commission begins on deposit; the balance is due before installation.
4
Installed, and entered in the Register
Delivered and placed white-glove in your space, its dossier signed into your keeping and its number recorded — permanently — in the OSSA Register.
The assurance
Commissions above threshold are held in third-party escrow — funds released only after you have inspected the installed work.
The truth
A cast, never a fossil. Renders are visualizations, never photographs of an install. Anatomy verified against published osteology.
The edition
Caps are permanent and public. When an edition closes, it is closed — the Register is never reopened.
Begin
Send one photograph of the room. We will show you the predator in it.
The first render is a courtesy — no cost, no commitment. It is simply the fastest way to know whether a room was waiting for one unforgettable object.
