THE CAMBODIAN 'STEGOSAUR' - AN ANACHRONISM FROM ANGKOR WAT?

Mystery creatures, and evidence in support of their existence, can turn up in the most unlikely places, but few can be as unexpected, surely, as Cambodia's centuries-old carving of an alleged stegosaurian dinosaur!

Stegosaurs constituted a taxonomic suborder of ornithischian ('bird-hipped') dinosaurs that existed from the mid-Jurassic Period to the early Cretaceous Period, i.e. approximately 170-120 million years ago. They lived predominantly in North America, Europe, and China, but at least one species is known from Africa, and possibly one from India too. Herbivorous and quadrupedal, the most famous morphological attributes of the stegosaurs were the double (occasionally single) row of very large, flat, upright plates running down the centre of their back, and the arrangement of long spikes (the so-called thagomizer) borne upon their tail. Proportionately, their head was very small relative to the rest of their body. Indeed, in the most famous genus, North America's Stegosaurus, their brain was only the size of a walnut whereas their body was the size of a van!

Whereas the last confirmed stegosaurs died out over 100 million years ago, one of Cambodia's most beautiful edifices, the jungle temple of Ta Prohm, was created a mere 900 years or so ago, and forms part of the Angkor Wat temple complex, which collectively is internationally famous for being the largest religious monument in the world. Dedicated to the Hindu deity Vishnu by the Khmer King Suryavarman who built it during the early 12th Century, Angkor Wat did indeed begin as a Hindu temple, for the Khmer Empire and in what was then its capital, Yasodharapura, now Angkor, but by the end of that century it had been transformed into a Buddhist temple.

Like other temples from this time period and Angkor Wat complex, Ta Prohm is intricately adorned with images from Hindu and Buddhist mythology as well as many depictions of animals. These latter include numerous circular glyphs each containing the carving of some local creature - but Ta Prohm also has one truly exceptional glyph unique to itself. Near to one of this temple's entrances is a circular glyph containing the carving of a burly quadrupedal beast ostensibly bearing a row of upright plates along its back - an image irresistibly reminiscent of a stegosaurian dinosaur!

This anomalous carving is very popular with local guides, who delight in baffling Western tourists by asking them if they believe that dinosaurs still existed as recently as 900 years ago and then showing this glyph to them. Could it therefore be a modern fake, skilfully carved amid the genuine glyphs by a trickster hoping to fool unsuspecting tourists? Or is it a bona fide 900-year-old sculpture? Having spoken to a number of people who have visited Angkor Wat and have viewed this glyph close-up at Ta Prohm, I am assured by all of them that it looks of comparable age to the other glyphs surrounding it, with no visible indications that it has been carved any more recently than any of the others there.

So how can this very intriguing, seemingly anachronistic depiction be explained? Some cryptozoologists cite it as proof that a stegosaurian lineage must have survived into modern times somewhere in this vicinity but has remained undiscovered by science (the notion that this carving may portray a living stegosaur appears to have been first promoted during the late 1990s, in a couple of books on Angkor Wat written by Michael Freeman and Claude Jacques). Others have suggested that perhaps it was inspired by the temple's architects having seen some fossilised stegosaur remains. And there also is the option that it is a stegosaur only by accidental design, i.e. that its plates are not a physical component of the creature, but merely background decoration inside the circle containing it, and that to associate them with the animal is therefore a mistake. Let's consider each of these possibilities.

If we ignore its plates, the rest of the creature does not actually look much like a stegosaur as depicted in palaeontological restorations, certainly not as depicted in modern restorations (i.e. in contrast to those dating from several decades ago, but which are still the ones commonly brought to mind by laymen who may not be familiar with up-to-date versions in palaeontological publications). In particular, its apparent lateral cranial horns are decidedly non-stegosaurian, and the stegosaurs' distinctive, characteristic thagomizer is conspicuous only by its absence in this glyph. Also contrasting with fossil stegosaurs are its relatively large head and short tail – the reverse condition to that more commonly exhibited by the former dinosaurs.

Then again, if a stegosaurian lineage has indeed somehow persisted into modern times, such differences from fossilised stegosaurs as those noted above are certainly not so radical that they could not have arisen during the 100 million years or so of continuing evolution that will have occurred from the early Cretaceous to the present day. One only has to compare, for instance, the relatively unspecialised range of mammals or birds existing during the early Cretaceous to the vast morphological diversity of mammalian or avian forms alive today to see just how extensively evolution can modify outward morphology during that particular period of time.

However, if anything as dramatic as a living stegosaur does indeed exist (or has done until very recently) anywhere within the area of Cambodia, one might reasonably expect rather more pictorial evidence of such existence than a single small carving tucked away amidst a myriad of other animal carvings. Yet I am not aware of any comparable design anywhere else in Asian art. To my knowledge, there is no suggestion of stegosaurian creatures in Cambodian mythology or folklore either, nor, indeed, in that of any other corpus of Asian traditions (thus contrasting very markedly, for example, with the extensive native beliefs associated with the mokele-mbembe in the Congo). And there is certainly no documented physical evidence for such a creature's reality – no preserved plates, skeletal remains, etc, described in any publication that I have ever encountered or seen any mention of during my researches.

Moreover, even fossil stegosaur remains so far disinterred in Asia are restricted to China (predominantly) and India (very controversially – much of these proved upon closer inspection to be derived from plesiosaurs instead!). This in turn reduces the likelihood that the 'stegosaur' glyph was carved 900 years ago by a local sculptor who had previously seen fossil remains of such a creature, unless (and which is certainly not impossible but unlikely) the sculptor had visited China and had seen such remains there?

Yet even if it does not represent a living contemporary (or a prehistoric fossil) stegosaur, might it conceivably depict some still-undiscovered modern-day animal that superficially resembles a stegosaur? If so, however, there do not appear to be any local sightings or lore on record concerning it

Another option is that it may be some local mythological creature (though I am unaware of any from this region of the world that match its appearance). Certainly, there is a varied mixture of the factual and the fictitious among the fauna depicted at Angkor Wat.

Directly below the stegosaur glyph, for instance, is one portraying a mystifying unidentified quadruped with cross-hatching on its body that may be meant to represent scales, plus a distinct series of dorsal ridges that in this instance are definitely part of the animal. Its somewhat pointed head is reminiscent of that of a pangolin or scaly anteater, which could also explain the cross-hatching.

Yet unless the depiction as a whole is very stylised (particularly its dorsal ridges), it does not closely resemble a pangolin (or indeed any other real, whole creature) in other morphological respects. However, as suggested elsewhere by German cryptozoologist Markus Bühler, might it represent the head of a wild pig? There is certainly a degree of resemblance. Alternatively, it may be some type of mythological entity.

Directly below that glyph, moreover, is one that portrays a typical Oriental demon, grinning maniacally at anybody spotting it there.

To my mind, however, by far the simplest and most plausible explanation for the enigmatic stegosaur glyph is that its resemblance to one of those plate-backed dinosaurs is an artefact – i.e. it is simply some form of local present-day known creature that has been carved with a plate-like decorative motif in the background, but which in turn has been wrongly associated directly with the creature. The reason that I favour this explanation is that such a motif can also be seen surrounding other carved animals of several different types enclosed within their respective glyph circles at Angkor Wat. These include birds, a water buffalo, deer, monkeys, and even mythological demons, as noted above (and in certain of these glyphs, moreover, the motif bears a resemblance to lotus leaves).

Although the plates surrounding the alleged stegosaur do seem somewhat more well-defined (but might this indicate some very selective modern-day enhancement by a hoaxer seeking to enhance its superficial stegosaur appearance?), their general shape and size are much the same as those surrounding other carved animals. In addition, this same plate motif is also present encircling the outer perimeter of the glyph circles enclosing the carved animals, including that of the 'stegosaur', as readily seen in the photograph opening this present ShukerNature blog article.

Looking closely at the latter creature, its head in particular is shaped very like that of a rhinoceros, as has also been commented upon elsewhere by Markus Bühler and various others. Even its 'cranial horns' resemble the long pointed ears of such mammals. Conversely, its back seems more arched than is true of rhinos, but this discrepancy could merely be due to stylising, or once again may simply be a design artefact, the creature having been depicted in this unnatural, hardly life-like pose (for a rhino) simply in order for it to fit more readily inside its circular setting.

Incidentally, adapting the shape of an animal during its depiction in order to fit it more snugly within a designated space for it is an option that I have already explored elsewhere on ShukerNature (click here) in relation to a second anomalous Angkor Wat carving - the so-called Cambodian moa.

Returning to rhinos and the suspect stegosaur: on the latter creature's body are indications of the skin pleats exhibited by Asian rhinos of the genus Rhinoceros (i.e. the great Indian R. unicornis and the Javan or scaled R. sondaicus, the latter of which definitely still existed in Cambodia 900 years ago, with the former possibly doing so too). Even the creature's lack of a nasal horn is not an obstacle to identifying it as a rhino of this genus, because female Javan rhinos are sometimes hornless.

Another line of speculation that has been proposed by some investigators is that the creature actually represents a very stylised portrayal of some form of lizard, suggestions having included a chameleon (though there is none in southeast Asia) or one of the several species of southeast Asian agamid known as mountain horned dragons Acanthosaura sp. However, any similarities between the carving and such reptiles seem far less apparent (if indeed present at all) to me than those readily visible between the carving and a stylised and/or modified-to-fit rhinoceros. Equally, whereas an even better fit for the creature's 'cranial horns' than the pointed ears of a rhino would be the horns of a wild ox, the rest of the creature's depiction is a better fit for a rhino than for an ox.

Of course, we shall never know for sure the intended taxonomic identity of the supposed stegosaur in this perplexing carving. However, it does seem much more likely to be a stylised depiction of some local known species rather than anything more radical. After all, it surely couldn't have been based upon a sighting of a real-life stegosaur...could it?

  1. It is quite clearly a moomintroll, though much further south than the known examples.

    Or a rhino.

  2. It does seem like you have it correct, a rhino with leaf-like decoration.

    I do not know a lot about dinosaurs, but I continue to regard stegosaurs as fictional creations of the wars between Cope and Marsh. I am strongly inclined to see them with the plates lying flat on their back.

    I wonder what animals today would be most analogous and if any have similar spikes on their tails?

  3. The tail of the animal carving in question looks reptilian to me (but no spikes).

  4. I always thought it was a dead ringer for a tapir.

  5. The weird thing is that I seem to remember with absolute certainty that someone claimed it to have been a 19th century addition made by some sculptor during temple renovations, but I can't seem to find the source of that memory.
    Huh.
    Maybe the debunking itself was a hoax if there's so little of it on the internet.

    1. Hi Cliodna, I've seen a number of people ALLEGING this to be the explanation, both online and in print (e.g. a reader's letter claiming something along these lines appeared in Fortean Times some years ago), but I've never seen any actual confirmation of it anywhere, and when two friends of mine visiting Angkor Wat sought out this Ta Prohm petroglyph specifically in order to photograph it for me (their photos appear in this article of mine), they informed me that it seemed to be no fresher than any of the others in close proximity to it. So my own opinion is that such claims are fallacious, and that it is genuine (i.e. of the same age as the other petroglyphs at Ta Prohm), not a modern-day creation added there as a hoax. All the best, Karl
