The "dinosaur" relief

The "dinosaur of Ta Prohm" [1] is a bas-relief in the medieval Cambodian (Khmer Empire) temple-monastery of Ta Prohm. Numerous reliefs of various different animals are present in the temple; the "dinosaur" is one of its more ambiguous artworks. The relief first gained modern notoriety in the late 1990s when the lobe-like features running down the animal's back were compared to the back plates of stegosaurian dinosaurs. The relief has since become a popular piece of "evidence" for the fringe belief that non-avian dinosaurs once coexisted with humans.

Contents

There is no academic consensus on what animal is depicted. The supposed back plates are likely stylized background foliage, present in many of the other reliefs at the temple. Other than this feature the animal bears little resemblance to stegosaurs and instead possesses marked anatomical differences, such as in the proportions and features of its head and in its lack of a thagomizer (tail spikes). Some of its anatomical features have been compared to chameleons and rhinoceroses. It is not certain that the relief was intended to depict a real animal at all since some reliefs in the temple depict mythical creatures. Since Ta Prohm is a popular site for film crews it has also been suggested that the relief could be a modern hoax.

History

The bas-relief [1] [2] is located in the temple-monastery [3] of Ta Prohm in Cambodia. [4] Within the temple, it is found in Gopura III, east of the main sanctuary. It is one of several roundels in a vertical strip of reliefs between the east wall of the main body of the gopura and the south wall of the porch. [3]

Ta Prohm was constructed in the late 12th century under Jayavarman VII of the Khmer Empire and was dedicated in honor of his mother, Sri Jayarajacudamani, in 1186. [2] Ta Prohm is decorated with numerous bas-reliefs, depicting various animals and mythical figures. Many of the animals can be identified but some are more ambiguous, such as the "dinosaur". [2] When exactly the relief was carved is unknown; [5] the temple in later times saw phases of being damaged, expanded, and modified. After the fall of the Khmer Empire in the 15th century, Ta Prohm and other temples were mostly left abandoned and neglected. Unlike some other temples, Ta Prohm has seen only little modern restoration work. [2]

The "dinosaur" relief first gained widespread recognition in modern times when its strange appearance was pointed out in a 1997 guidebook, [1] [2] Angkor Cities and Temples by Michael Freeman and Claude Jacques. [2] In their later 1999 book Ancient Angkor, Freeman and Jacques again highlighted the relief and referred to it as "a very convincing representation of a stegosaur". [3]

Description

The animal depicted in the relief has a convex-shaped back, lined with a series of ornaments superficially reminiscent of the plates of stegosaurian dinosaurs. [4] It is likely that these supposed plates are meant to be stylized lotus leaves or petals, which are also featured in nearby reliefs and throughout the temple's artwork, sometimes in a nearly identical manner. [4] The ornamentations of reliefs depicting a water buffalo and a bird have for instance been identified as nearly identical; in these cases the ornamentation is clearly not meant to represent back plates. [2]

Identification

Conventional identifications

The relief has garnered relatively little scientific interest. [6] Conventional identifications of the animal depicted, taking into account the likelihood that the "plates" are stylized background foliage, [1] [5] include a chameleon, [1] [2] a mountain horned lizard, [2] a rhinoceros, [1] [2] [5] a water buffalo, [2] or a boar. [5] Although the head anatomy corresponds to that of a rhinoceros, the animal lacks a nose horn. It is possible that it originally had a horn that later weathered away or that the species depicted is one with a much less pronounced horn, such as the Bornean rhinoceros, historically present in Cambodia. [2] The arched back and large tail has been interpreted by some as more suggestive of a chameleon. [2] It is also possible that the animal is a mythical one since other mythical creatures are depicted elsewhere in the temple, including very close to the "dinosaur"; the relief at the bottom of the same strip is a mythical dog-like creature with the head of a human or monkey. [2]

Another possibility is that the relief was either made [2] [5] or altered [2] by a modern hoaxer. Ta Prohm is often used by film crews and this particular image could have been carved as a joke. [5] The relief is relatively lighter than surrounding carvings, which could suggest that it was made or altered relatively recently. Alternatively, this could have resulted from it being cleaned or from visitors making molds of it. [2]

Fringe theories

Reconstruction of Stegosaurus; the animal in the relief differs in several notable aspects, including the head, neck, limb and tail anatomy, the number and arrangement of "plates", and the lack of a thagomizer (tail spikes) Stegosaurus stenops sophie wiki martyniuk flipped.png

Some adherents of fringe theories, such as Young Earth creationists and cryptozoologists, have put forth the "dinosaur" of Ta Prohm as evidence that humans and non-avian dinosaurs once coexisted. [1] [2] [5] The relief has been widely publicized online, particularly on websites and blogs by creationists, including by the major creationist organization Answers in Genesis. [2] A replica of the relief is exhibited at the Creation Evidence Museum of Texas, [1] [2] where the conclusion that it represents a stegosaur is strongly encouraged. [2]

There is no evidence that the animal depicted is a stegosaurian dinosaur. [5] The Khmer Empire was an advanced, highly populous, and literate society. It is unlikely that the presence of stegosaurs in Cambodia only a few centuries ago would not have been documented in any other way than through a single relief in a temple. [2] Beyond the superficial resemblance of the plates, the animal also shares few similarities with stegosaurs. [2] Even if interpreted as plates, the structures along the animal's back do not resemble stegosaurian plates, which were greater in number and placed in two rows. [2] The animal is depicted with two large structures on the back of its head, either horns (not known from any stegosaur) or large ear flaps (which would suggest that it is a mammal). [2] [4] [5] It is also depicted with a short neck, wide snout and large head. These features correspond to rhinoceros anatomy and are very different from the long neck, pointed and narrow snout, and small heads of stegosaurs. [2] The animal has front and back legs of around the same size, whereas stegosaurs had back legs significantly larger than their front legs. [2] The tail appears to be very low to the ground whereas dinosaurs are now known to have held their tails well above the ground. [2] The animal does not have a thagomizer (tail spikes), one of the most striking and unique features of stegosaurs. [2]

Scientific understanding of the fossil record suggests that all dinosaur lineages other than birds went extinct during the Cretaceous–Paleogene extinction event, 66 million years ago. [5] [7] The complete absence of non-avian dinosaur fossils in Cenozoic layers contrasts sharply with the good record of the group in Mesozoic layers and their survival would require ghost lineages on an unprecedented scale. [7] Stegosaurs appear to have been declining already in the Early Cretaceous. They may have gone extinct prior to the extinction event since no certain stegosaurian fossils are known from the Late Cretaceous. [8] If the relief were to represent a stegosaur, it could conceivably have been based on fossils rather than a live specimen. Although no stegosaur fossils are known from Cambodia, several genera are known from relatively nearby in China, such as Huayangosaurus , Tuojiangosaurus and Wuerhosaurus . [2]

Stegosaurus is a genus of herbivorous, four-legged, armored dinosaur from the Late Jurassic, characterized by the distinctive kite-shaped upright plates along their backs and spikes on their tails. Fossils of the genus have been found in the western United States and in Portugal, where they are found in Kimmeridgian- to Tithonian-aged strata, dating to between 155 and 145 million years ago. Of the species that have been classified in the upper Morrison Formation of the western US, only three are universally recognized: S. stenops, S. ungulatus and S. sulcatus. The remains of over 80 individual animals of this genus have been found. Stegosaurus would have lived alongside dinosaurs such as Apatosaurus, Diplodocus, Camarasaurus and Allosaurus, the latter of which may have preyed on it.

The King dedicated the temple to his father Dharanindravarman II (Paramanishkalapada) who was King of the Khmer Empire from 1150 to 1160. The temple consists of a single shrine located on one level and surrounded by enclosure laterite walls. Like the nearby Preah Khan and Ta Prohm the temple was left largely unrestored, with numerous trees and other vegetation growing among the ruins. In 1998, the World Monuments Fund (WMF) added the temple to their restoration program and began work to stabilise the structure to make it safer for visitors.

<i>Kentrosaurus</i> Extinct genus of dinosaurs from late Jurassic in Lindi Region, Tanzania

Kentrosaurus is a genus of stegosaurid dinosaur from the Late Jurassic in Lindi Region of Tanzania. The type species is K. aethiopicus, named and described by German palaeontologist Edwin Hennig in 1915. Often thought to be a "primitive" member of the Stegosauria, several recent cladistic analyses find it as more derived than many other stegosaurs, and a close relative of Stegosaurus from the North American Morrison Formation within the Stegosauridae.

<i>Dacentrurus</i> Extinct species of reptile

Dacentrurus, originally known as Omosaurus, is a genus of stegosaurian dinosaur from the Late Jurassic to Early Cretaceous of Europe. Its type species, Omosaurus armatus, was named in 1875, based on a skeleton found in a clay pit in the Kimmeridge Clay in Swindon, England. In 1902 the genus was renamed Dacentrurus because the name Omosaurus had already been used for a crocodylian. After 1875, half a dozen other species would be named but perhaps only Dacentrurus armatus is valid. Finds of this animal have been limited and much of its appearance is uncertain. It was a heavily built quadrupedal herbivore, adorned with plates and spikes, reaching 8–9 metres (26–30 ft) in length and 5 metric tons in body mass.

<i>Huayangosaurus</i> Extinct genus of dinosaurs

Huayangosaurus is a genus of stegosaurian dinosaur from the Middle Jurassic of China. The name derives from "Huayang" (華陽), an alternate name for Sichuan, and "saurus", meaning "lizard". It lived during the Bathonian to Callovian stages, around 165 million years ago, some 20 million years before its famous relative, Stegosaurus appeared in North America. At only approximately 4 metres (13 ft) long, it was also much smaller than its famous cousin. Found in the Lower Shaximiao Formation, Huayangosaurus shared the local Middle Jurassic landscape with the sauropods Shunosaurus, Datousaurus, Omeisaurus and Protognathosaurus, the ornithopod Xiaosaurus and the carnivorous Gasosaurus.
