Authentic Dinosaur Skeletons

Triceratops Skull

Triceratops Skull, T. Horridus (MARSH 1889), Lance Creek formation, Weston County, Wyoming, U.S.A

Period : End of the Cretaceous period (67-65 million years).

It was a beautiful discovery, made by the excavation laboratory when this skull was extracted from its gangue. Finding dinosaur bones remains a magical moment, on which the breath of adventure passes.

The Triceratops comes from the Ornithischian order, more specifically the marginocephale group, which includes all dinosaurs with bony ruffled collars or a developed cranial skullcap. This triceratops comes from the family of Ceratopsides, which have short bony collars.

The triceratops was a large dinosaur, noticeable for its imposing head, which stemmed from this massive animal. Its name literally means "head of three horns."

As we can see on the image below, it had two long horns stemming from its forehead and one short one stemming from its nose. It also had a large bony collar behind its skull which likely, according to paleontologists, protected both his neck and shoulders. The fact that it had four legs probably make it look like a giant rhinoceros. It could grow up to 7.5 meters long and weigh up to 5 or 6 tons.

This species of dinosaur was discovered by John Bell Hatcher in 1886. At the end of the 19th century in North America, the American Barnum Brown collected several archaeological remains. We hypothesize that this type of dinosaur probably lived in groups on the plains, but also in the forests in order to benefit from the mild climate. With its low head, it picked herbaceous plants and could snap branches with its horns in order to catch leaves that it could chew with its teeth. What is rare about its beak which was situated on its head, is that it never had teeth.

Paleontologists have several theories regarding the usage of its horns and cranial shield, one of which is that they served as defense protection against large predators, such as the Tyrannosaurus rex, which lived during the same period in the same region. It is one of the most recognizable dinosaurs, probably because it is often represented engaging in mythic battles with the very same Tyrannosaurus rex. Despite the formidable power and ferocity of the Tyrannosaurus rex, it seems like the Triceratops could have come out on top in many a battle.

The osteological study of the head shows that the joint between the head and neck is spherical and situated at a point of balance on the head. Thus, the Triceratops could turn to face its enemies in all directions, both quickly and with precision.

The second hypothesis advanced by paleontologists is that its horns and imposing cranial shield could also serve as an affirmation of the dominant male role in the pack and aid in the seduction of females.

The skull at hand gives us an opportunity to consider the exceptional size of the dominant males in question.

This skull is a beautiful specimen provided with its osteological restoration maps and has perfect traceability. The nose horn and the undeformed nasal bone have a protruding and original shape. It is probable that fighting took place between the males who were then fighting each other with horns. The collar could also have been used for thermal regulation. Vascularised, it was capable of storing or releasing energy depending on the exposure. Finally, the skull shows the three famous horns.

The large cervical collar consists of a solid bone blade, in good condition for conventional restoration and corresponding to the plan which is available for consultation with our staff. The fact that this collar is not perforated indicates that its main role was to defend rather than anchor the jaw muscles.

Faced with this massive skull which completely filled the space and which the animal was able to support thanks to the first three cervical vertebrae which were fused together, thus forming a very load-bearing monobloc bone structure, it is easier to understand that the massive skull structure of the Triceratops could be fossilized more easily than that of other, less robust skulls and thus achieve such perfection in the quality of the fossilization.

The skulls of large dinosaurs remain rare, are the main element of the skeleton, and therefore remain absolutely essential. Among all the dinosaurs, we cannot find skulls more important than that of the Triceratops. The skull and its lower jaw have been professionally fitted by our Laboratory, in order to easily find its place in your home.

(former name Brontosaurus)

A very large quadruped saurischian herbivorous dinosaur of the genus Apatosaurus (formerly called Brontosaurus, Greek: "thunder lizard", until it was discovered the two animals were the same)

Period : Late Jurassic, Early Cretaceous

Length : About 21-27m (70-90ft) 

Weight : Roughly the weight of four elephants, about 30 tons

Apatosaurus had a long, whiplike tail, stout legs, and a long neck. It was herbivorous and dwelled on land, possibly in forests, using its long neck to feed on leaves from trees. The eyes and nostrils were located toward the top of the skull.

It flourished in the late Jurassic Period. Apatosaurus' bones and those of other sauropods have long been excavated in the Morrison Formation, of the late Jurassic and early Cretaceous strata in Colorado, Wyoming, and other western states.

No satisfactory skull specimen has been discovered attached to an Apatosaurus, and for many years an incorrect Camarasaurus-like head was mounted on the famous skeleton display at the American Museum of Natural History in New York City.

On the contrary, this Apatosaurus was found with its head, making it a Treasure of Paleontology.

Other Authentic Skeletons

Mammuthus primigenius

Very important and impressive skeleton of a Mammoth

Mammuthus primigenius 
Age : about 40,000 - 50,000 years
Size : 6m x 3.5m Unique size, and huge tusks. (54 - 56 kg.)
Due to the huge size of the tusks, special additional supports were required under each tusk (see photo). One of the largest specimens we ever found!

"The mammoth is an iconic animal of prehistory. It is brought closer to us by the fact that it lived with Man, and that we are still finding carcasses with their flesh and hairy skin preserved in the frozen wastes of Siberia.
But its disappearance around 10,000 years ago, even if some managed to survive until 3,700 years ago in Siberia's Wrangel Island, went hand in hand with the extinction of many other species in the Old and New World.

Other periods, when species disappeared, some to a far greater extent, have marked the history of life on Earth, and it is fascinating to measure the importance of these facts, and see what the disappearances of mammoths and other large vertebrates can teach us about extinctions and their connection with climate change."

This species was contemporary with Neanderthals in the Middle Palaeolithic and Homo Sapiens in the Upper Palaeolithic and died out around 12,000 years BC.

The mammoth was the biggest land mammal of all time, It is the representative of a marvelous species that has clearly marked our imaginations and film culture.
It is also the animal that symbolizes prehistory par excellence, as witness the fact that it represented over 100 times in the famous prehistoric cave at Rouffignac in France. Artistically it has remained just as contemporary in the 20th and 21st centuries in films such as the Ice Age series.

This specimen is presented in a walking position. Its exceptionally well-preserved condition means that it has only a few standard minor restorations. This magnificent mammoth skeleton could be baptized in a private ceremony: it longs to find a new place to settle down!

This remarkable mammoth specimen is also one of very few in the world possessing all the commercial authorizations. It can thus be promoted, exported, resold, and used publicly for commercial purposes.

The mammoth conveys an image of strength, as well as an eco-environmental message, and arouses visitors' empathy in a touristic venue. It is a distant cousin of elephants and the illustrious representative Babar, the hero of the children's stories created by Jean de Brunhoff.

As a result, it has been an incredible vector in terms of commercial impact and advertising for industries. For example, the Cave de Montfrin (France) boasts a specimen that has considerably increased its turnover and doubled its visitor flows, while the Faena Hotel in Miami (United States) has a mammoth entirely covered in gold leaf on show.

The mammoth, an extinct prehistoric animal, also looks set to become the animal of the future and a burningly topical subject. This is because numerous scientific projects are aiming to recreate it. Since this possibility is gradually emerging at a time when genetic research and cloning are making huge progress, it is worth considering that the acquisition of such a remarkable skeleton would decidedly position its owner or its owner's activities as a subject very much in the public eye, which will continue to draw attention in the century opening out to the younger generations.

Your future mammoth fossil can be presented on a base in blond oak, dark oak, with moldings, or on a modern base with pure lines (possibility of lacquering the base, or gilding it entirely, please consult us on these points), reconstructed according to the standards of modern paleontology with the bones found in a mammoth fossil bed.

Placed in a scientifically correct position and thus giving a strong and spectacular visual impression, this mammoth skeleton, a true work of natural art in the spirit of the Surrealists, is indisputably still a rare and exceptional subject that Eric Mickeler has had the good fortune to appraise, for some twenty years now, as he was historically the expert on all the mammoth specimens that have made the headlines.

Woolly Rhinocerous

Important Woolly Rhinoceros skeleton.

Period : Superior Pleistocene, Quaternary Era

Dimensions : 4.5m x 1.1m x 1.6m

This woolly rhinoceros, whose bones were found in a fossil bed, in possible company with bones from other subjects, is a rhinoceros with septum nostrils, named so due to the strong bony nasal septum that supports the powerful horn.

It is also more commonly known as the Woolly Rhinoceros because of the coat it had. It lived during the last two ice ages and disappeared with the last ice retreat, about 10,000 years ago.

It can be found on the walls of many prehistoric caves painted by the first humans. This beautiful specimen is presented on a base made of blond oak woodwork.

Horns restored. Rare.

Mural of Pectens


Limestone with Pectinidae, a witness of the Miocene Sea in the South-East of France.

The size of the Pectens (fossilized scallops) varies between 10 and 15 cm. They pile up naturally and give a natural response to the works of the French artist César.

This natural work of art can be presented in a stone frame, in a wall recess, or used as a facade for a chimney hood. It also produces an extraordinary effect in a bathroom or on the walls of an indoor swimming pool.

Approximate dimensions of a plaque: height 205 cm; width 110 cm; depth. 23 cm; other dimensions are available on request.

(Sea Lily)

Sea Lily Fossils (SEIROCRINUS SUBANGULARIS, CRINOIDEA FAMILY), Lower Jurassic, Lias Epsilon II 3 Formation in Holzmaden, South of Germany.

Different sizes are available.
The Seirocrinus subangularis is scientifically part of the Echinoderm class, which in Greek means "spikey skin." It belongs to a very ancient marine animal group; its first fossils appeared around the Cambian period.

There are about 7,000 species living today, the most famous being the sea urchin, and 13,000 other species which have disappeared.

With a supernatural, almost surreal look, they bear certain unique characteristics in the animal world, such as a pentaradiant symmetry and an aquifer system.

Despite its name and flowery shape, it is far from being a plant. Rather, it is a "tentacular" sea animal. It expands into a crown shape in order to feed through a filtering organ which captures plankton.

Sea lilies lived attached to a drifting piece of wood amidst colonies or, following the example of this magnificent specimen, as an isolated animal drifting freely in the ocean. We notice, at the bottom of the lily, the chunk of wood to which it attached itself, fossilized at the same time.

The fossil's black tint, and its elegant and sober presentation, against the stone panel, heighten the prehistoric evocation, as an important natural modern work of art. This specimen, aside from its remarkable size and its incomparable beauty, is absolutely exceptionally preserved.

Palm Frond fossil

Out of stock

We thank you for consulting us on the replenishment date and your orders.

Remarkable Palm Frond Fossil, with fossilized fish 

50 million years ago, in a climate much like that of Florida today, this palm frond reigned in south-west Wyoming. The whole region was then a genuine vegetal and aquatic paradise for tortoises, fish, crocodiles, and other aquatic species.

Meanwhile, luxuriant vegetation reigned on land, the evocation of which is brilliantly illustrated by this spectacular fossilized palm tree leaf, which is very representative of the primitive and magnificent flora of the Eocene Epoch.

The palm tree leaf was possibly surrounded by several fish which, lying on the sea bed, were fossilized together with it, in such perfect circumstances that no fish has been modified or added by man. The tips of the leaf are entirely natural, with no corrective touches, notwithstanding the fact that the delicacy of the points is utterly unique.

Finding intact fossilized palm trees is very rare because of their fragility. Thus, few specimens of good size and of remarkable quality, like those of THÉTIS, have been excavated.
