Christie’s London auctions Spike, a Caenagnathid dinosaur, on December 11th, estimated at £3-£5 million, one of the most complete specimens ever discovered.
Christie’s London is preparing to make paleontological history. On 11 December 2025, the auction house will present Spike, an extraordinarily preserved Caenagnathid dinosaur, as the star of its inaugural Groundbreakers: Icons of Our Time sale. The estimate sits between £3,000,000 and £5,000,000. And for good reason.
This is a sub-adult dinosaur from the Late Cretaceous period, roughly 68 million years old. The measurements are substantial: 199.5 x 198.5 x 67 centimetres. What makes Spike genuinely extraordinary is completeness. Approximately 100 beautifully preserved fossil bones tell the story of a creature that’s only barely understood by modern science. It’s one of the most complete Caenagnathid specimens ever discovered.
The specimen emerged during the 2022 field season. Recent scientific work has determined something fascinating about this family of dinosaurs: they were heavily feathered. There’s a rare marking on Spike’s wrist that might provide further evidence of this. The morphological features appear distinct from previously known Caenagnathids, suggesting there’s still much to learn.
A Question of Rarity
Since the first Caenagnathid was published in scientific literature in 1940, only a handful of comparable specimens have been discovered. None have ever come to auction until now.
That’s the context. Spike isn’t just rare within the fossil market. It’s rare full stop.
James Hyslop, Head of Department, Science & Natural History at Christie’s, puts it plainly: “Spike is a truly exceptional specimen, and it is a great honour to present him here at Christie’s. We’re looking forward to welcoming visitors to King Street to meet Spike in person. Through Christie’s Select, collectors and enthusiasts will also have the opportunity to explore Spike in immersive VR, experiencing this epic dinosaur in their own environment – from anywhere in the world.”
The VR component is significant. Christie’s Select on Apple Vision Pro allows prospective collectors to view Spike at true-to-life scale in their own spaces. The spatial computing capabilities of visionOS enable detailed exploration from every angle. It’s a fully immersive experience ahead of the auction, and it addresses a practical reality: not everyone can get to King Street.
The Caenagnathid Enigma
Caenagnathids occupied a peculiar ecological niche. These bird-like dinosaurs belonged to the oviraptorosaur group, inhabiting what’s now North America during the Late Cretaceous. The name derives from Greek, meaning “recent jaw,” a reference to their distinctive jaw structures.
They were likely omnivores. Beak-like jaws, powerful claws, distinctive skeletal features. The confirmation of extensive feathering adds another layer to our understanding of the evolutionary connection between dinosaurs and modern birds. But honestly, much about their behaviour and ecology remains unknown.
That’s what makes each new specimen crucial. Whilst Tyrannosaurus and Triceratops have yielded numerous specimens over decades of fieldwork, Caenagnathids remain elusive. Each discovery provides essential data points for researchers attempting to reconstruct the biology and evolutionary relationships of these animals.
Spike offers something more: morphological features that appear distinct from other known Caenagnathids. The wrist marking is particularly intriguing. It might be further evidence of feathering. Or it might indicate something else entirely.
Public Access and Scientific Value
Christie’s will present Spike in a curated exhibition at King Street from 6 to 11 December 2025, immediately before the auction. This isn’t just a pre-sale viewing. It’s a rare opportunity for researchers, collectors, and the general public to encounter one of the most complete Caenagnathid specimens in existence.
The exhibition recognises something important: objects of this scientific and cultural significance transcend commercial value. Making Spike available for public viewing acknowledges a responsibility to facilitate broader engagement with paleontological research. Visitors will stand in the presence of a creature that walked the earth 68 million years ago. That’s not a small thing.
For those who can’t attend in person, comprehensive information about viewing through Christie’s Select is available via the auction house’s digital platforms. Global audiences can participate.
The Groundbreakers Context
Spike headlines Christie’s inaugural Groundbreakers: Icons of Our Time auction, but it doesn’t stand alone. The sale presents a curated selection of 30 lots spanning natural history, cinema, music, literature, fashion, and technology. Cultural innovation from the 20th and 21st centuries.
This curatorial approach positions Spike not merely as a fossil specimen but as an icon of humanity’s fascination with deep time and vanished worlds. The auction’s thematic breadth creates a context where Spike emerges as a symbol of nature’s creative power across geological epochs.
Additional treasures will be revealed in the coming weeks. The auction forms part of Christie’s London Classic Week, running from 2 to 11 December 2025.
Science Meets Commerce
The appearance of scientifically significant specimens at public auction raises familiar questions about the balance between private collecting and institutional research access. Spike’s sale may place it in a private collection, potentially limiting research access. But private collectors have historically played crucial roles in supporting paleontological research, funding expeditions, and ultimately donating or lending specimens to institutions.
Christie’s has established protocols that facilitate ongoing scientific study of significant natural history specimens, regardless of eventual ownership. The auction house understands its position as a bridge between private collectors and the scientific community. Specimens of Spike’s calibre carry responsibilities beyond commercial transaction.
The estimate of £3,000,000 to £5,000,000 reflects exceptional preservation and completeness. It also reflects broader market dynamics. Major dinosaur fossils have achieved increasingly substantial prices at auction in recent years. This market evolution has enabled more extensive fieldwork and preparation of specimens that might otherwise have remained undiscovered.
Preparation and Presentation
What you see in the striking photograph accompanying Christie’s announcement represents months or potentially years of painstaking work. Each bone must be carefully extracted from its matrix, stabilised, and prepared to reveal surface features without compromising structural integrity. The mounting requires careful engineering to support the specimen’s weight whilst presenting it in an anatomically accurate and visually compelling pose.
The result showcases Spike in a dynamic posture that suggests the creature’s movement and behaviour whilst alive. This preparatory work represents a substantial investment. The quality of preparation directly impacts both scientific utility and aesthetic presentation. Sophisticated collectors and institutions evaluate this carefully.
Technology and Tradition
Christie’s deployment of immersive VR viewing exemplifies how auction houses are adapting to serve globally distributed clientele whilst maintaining high standards of presentation. The Groundbreakers auction concept positions exceptional specimens within broader cultural narratives rather than isolating them as scientific curiosities.
Presenting Spike alongside objects from cinema, music, literature, fashion, and technology makes an implicit argument: this fossil is a cultural icon, an object that speaks to fundamental human impulses toward exploration, discovery, and connection with deep time.
This contextualisation may broaden the potential collector base, attracting individuals whose primary collecting interests lie elsewhere but who recognise the cultural and historical significance of exceptional natural history objects. The cross-pollination of collecting categories is increasingly prominent at the upper echelons of the auction market.
Legacy and Future Access
Regardless of the auction outcome, Spike has already secured a place within paleontological history. The extensive documentation and study conducted prior to auction will contribute to scientific understanding of Caenagnathids. The specimen’s public presentation through exhibition and immersive technology will inspire with the wonder of paleontological discovery.
The eventual home will determine the nature of future access and study. Christie’s track record suggests careful consideration of these factors in working with both consignors and prospective purchasers. Significant specimens should remain accessible to researchers when appropriate.
For the broader collecting community, Spike’s appearance validates natural history as a collecting category capable of producing objects of extraordinary significance and value. The specimen demonstrates that systematic field collection, careful preparation, and strategic marketing can bring exceptional natural history objects to global attention, potentially funding further exploration and discovery.
December Approaches
As Christie’s King Street galleries prepare to welcome visitors, Spike is ready to make history once more. From its origins 68 million years ago in the Late Cretaceous ecosystems of North America, through millennia-long preservation within ancient sediments, to its discovery in 2022 and forthcoming auction debut, this Caenagnathid specimen embodies the enduring human fascination with vanished worlds.
The Groundbreakers: Icons of Our Time auction on 11 December 2025 promises to be a landmark event. Spike serves as an incomparable ambassador for the wonder of paleontological discovery. Whether examined in person at Christie’s London exhibition, explored through immersive VR, or appreciated through photographic documentation, Spike offers a tangible connection to an ancient world.
For collectors, institutions, and enthusiasts, this is an opportunity unlikely to recur: the chance to acquire one of the finest examples of a rare dinosaur family. A specimen that bridges scientific research, natural history, and cultural iconography.
As the hammer falls on 11 December, a new chapter begins in Spike’s journey through time. A journey that connects the Late Cretaceous past with an uncertain but fascinating future.
The specimen can be viewed in person from 6 to 11 December 2025 at Christie’s London, King Street. Further details about viewing via Christie’s Select are available at Christie’s website.
