Geology museums of mainland Europe: The Galerie de Paléontologie et d’Anatomie Comparée, Paris

Jon Trevelyan (UK)

The Galerie de Paléontologie et d’Anatomie Comparée, part of the Muséum national d’Histoire naturelle, is located in the Jardin des Plantes in Paris. Established in 1898, the gallery showcases an extensive collection of fossils and anatomical specimens, offering insights into the evolution of life on Earth.

The gallery is housed in a striking Art Nouveau building, featuring large glass windows and intricate ironwork. The interior is divided into three levels:

Ground floor: dedicated to comparative anatomy, displaying nearly a thousand skeletons and anatomical models.
First floor: focuses on fossil vertebrates, including dinosaurs and mammals.
Second floor: features fossil invertebrates and plants, illustrating the diversity of life forms through time.

The layout encourages a chronological journey through the history of life, with specimens arranged to highlight evolutionary relationships.

In fact, the Galerie de Paléontologie et d’Anatomie Comparée isn’t just a container for fossils – it’s a statement about nineteenth century science, display and museology in France. As such, it offers a comprehensive and immersive experience into the history of life on Earth. It’s impressive fossil collection and thoughtful displays make it a must-visit for enthusiasts of palaeontology and evolutionary biology, and it was certainly on my to-do list when I visited the French capital in 2025.

Architecture

The building was completed in 1898, designed by the architect Louis-Jules André with structural input by Albert-Félix-Théophile Thomas. It was part of a late nineteenth-century push to create ‘scientific palaces’, that is, large, open, well-lit halls to display specimens.

Fig. 4. The main hall on the ground floor.

As I said above, its style is Art Nouveau (with Beaux-Arts influences), with an iron framework visible in the interior (Fig. 5Q). It has tall, arched windows along the walls, allowing natural light to illuminate the specimens, with long, rectangular halls and high ceilings that give the sense of a ‘temple of science’.

Fig. 5. An example of the elaborate metal work at the museum.

Iron and glass are prominent, a hallmark of the era’s industrial construction applied to museums (think Grand Palais). The iron skeleton allows open floor space, so massive skeletons can be displayed upright, which is crucial for vertebrates like sauropods. Large glass display cases along the sides house smaller specimens, fossils, and anatomical models.

And, as explained above, there are three levels, with galleries arranged to take visitors through comparative anatomy (ground floor), fossil vertebrates (on the first floor), and invertebrates and plants (on the second floor). And there are ornamental touches everywhere – iron balustrades, wooden display cabinets, tiled floors – which make it both functional and aesthetically satisfying.

Historical context

So why was it built? By the late nineteenth century, natural history collections in Paris had grown enormous. Cabinet-style collections of the eighteenth century (think Buffon) were considered too cramped and ‘unsystematic.’ The Galerie was conceived to display skeletons in life-like poses, to show evolutionary relationships in a comparative way, and merge palaeontology with comparative anatomy.

At the time, palaeontology was booming. Fossil finds across Europe, Africa and South America were reshaping understanding of evolution, so the Galerie was intended not only for public education but also for research, with specimens accessible to scholars.

Notable contributors included Georges Cuvier, whose legacy looms large. Despite the fact that he died decades before the museum opened, it still carries his vision of comparative anatomy. And curators and palaeontologists of the late nineteenth century ensured that skeletons were mounted in lifelike, scientifically informed postures – a novelty at the time.

The museum opened in 1898, survived two World Wars, including occupation and bombardment threats, and continues to host research today, while also serving as a major public museum. That is, the building represents the ‘temple of science’ ethos of late nineteenth century France – visible iron, open halls, and specimens organised by scientific logic rather than aesthetic whim. It’s also a reflection of France’s ambition to be a world leader in natural sciences, especially palaeontology, comparative anatomy and taxonomy.

Specimens of historical and scientific importance

The museum holds type (specimen) material for hundreds of taxa described by nineteenth- and twentieth-century French palaeontologists, including dinosaurs, mammals and marine reptiles from Madagascar, North Africa and Europe. Many of Cuvier’s original specimens, including the fossil elephants and marine reptiles he used in his foundational work on extinction, are preserved here.

Fig. 8. *Diceratherium lemanensis* is an early rhinoceros belonging to a now-extinct group that flourished in North America and Eurasia after the Eocene. It was a stocky, short-limbed browser with two small horns side by side on its snout.

And in its palaeontological archives, there are drawings, field notes and plates by early researchers, such as Cuvier, Blainville and d’Orbigny, consisting only part of the historical collections.

Fig. 9. *Diplocynodon ratelli*. *Diplocynodon ratelli* is an extinct species of alligatoroid crocodilian that lived in Europe during the Early Miocene epoch.

So the Galerie is not just a display hall – it’s an architectural and scientific statement, blending iron-and-glass industrial design with Beaux-Arts style. Its long, high-ceilinged halls are intentionally designed for large skeletons and life-size reconstructions – a big leap from earlier cramped cabinet displays. Its historical mission was both educational and scientific, bridging the gap between research collections and public exhibitions. And visiting the Galerie, you’re seeing more than fossils – you’re seeing nineteenth-century scientific culture frozen in architecture, where the building itself teaches about scale, structure, and the logic of nature.

The exhibits

The palaeontology galleries hold roughly seven million fossil specimens, making it one of the world’s largest fossil collections. Of these, only a few hundred are displayed, but they’re carefully chosen to illustrate major evolutionary transitions.

And the exhibition areas are arranged by time and taxonomy, with the focus on vertebrate palaeontology, although the upper levels include invertebrates and plants.

Jurassic and Cretaceous dinosaurs

You can’t but notice the Diplodocus carnegii cast, much like ‘Dippy’ at the Natural History museum in London, as both which were gifts from Andrew Carnegie in the early twentieth century, and part of the famous series of Diplodocus casts sent to major museums worldwide. The Paris specimen dominates the central hall.

Fig. 11. *Compsognathus longipes* was as chicken-sized dinosaur and one of the smallest known when first discovered and one of the first complete dinosaur skeletons ever found. It was a swift, agile predator that hunted small reptiles and insects along the shores of a shallow tropical sea, and its delicate bones were preserved in the fine-grained limestones of Solnhofen.

The gallery houses a cast of the Tyrannosaurus rex skull, providing a close-up view of this formidable predator’s features. It’s an excellent specimen for studying theropod cranial anatomy. There is also an Allosaurus skeleton, mounted in a dynamic, life-like pose, one of the first reconstructions in France to show a predatory stance, tougher with Iguanodon bones (Figs. 12V and 13S), being French material that complements the classic Belgian discoveries.

Fig. 12. The cast of *T. rex* skull with the *Allosaurus* cast behind it.

Fig. 13. A cast of one of the *Iguanodon* skeletons from Belgium.

Displayed is a skeleton of Lapparentosaurus madagascariensis, a mid-Jurassic sauropod from Madagascar, described by Albert-Félix de Lapparent, the great French palaeontologist. Its preservation and articulation make it one of the best Jurassic dinosaurs outside the Americas.

Note also the Carnotaurus cast, which is an unusual South American abelisaurid.

Marine reptiles and early amphibians

Ichthyosaurs and plesiosaurs from the Jurassic are represented by elegant, fully articulated skeletons showing the adaptation to marine life. And there is a Mosasaurus skull, from the Cretaceous chalks of Maastricht, echoing the early discoveries that shaped palaeontology itself.

Fig. 15. *Thalassiodracon hawkinsii* is an extinct genus of plesiosaur that was alive during the Late Triassic-Early Jurassic, and is known exclusively from the Lower Lias of England. This is the type and only species.

Note also the temnospondyl amphibians, which were early Triassic giants showing the transition between amphibians and reptiles.

There are also copious display cabinets and trays of bivalves (Figs. 16 and 17), gastropods (Figs. 18 to 21) corals (Fig. 22) and stromatolites (Fig. 23).

Fig. 16. A couple of bivalves – *Isognomon maxillata* from the Pliocene of Italy (left) and *Pinna folium* from the Sinemurian of France (Jurassic).

Mammals

Miocene mammals: these include:

Deinotherium giganteum: the strange down-curved-tusked elephant relative. The Paris specimen is a centerpiece – immense and beautifully mounted.
Indricotherium (Paraceratherium) cast: the largest land mammal ever known, and an educational reconstruction shows its size.
Hipparion and Anchitherium: early horse skeletons from French Miocene deposits, tracing horse evolution. These were crucial in nineteenth-century evolutionary debates.

Other mammals: there a fossils of sabre-tooth cats (Smilodon, Machairodus and Homotherium, Fig. 24), Pleistocene lions, early whales (Basilosaurus and Cynthiacetus) and megacerine deer, all illustrating mammalian diversity after the dinosaurs.

Fig. 24. *Smilodon populator* (sabre-tooth cat) from the Upper Pleistocene of Argentina.

There are also other interest mammals including. Arsinoitherium zitteli (Fig. 25), Diaceratherium lemanense (Fig. 26), Megatherium americanum, the giant sloth (Fig. 27) and the ‘Palaeotherium de mormoiron’ (Fig. 28).

Fig. 25. *Arsinoitherium zitteli*, an extinct genus of paenungulate mammal, from the Lower Oligocene of Africa.

Fig. 26. *Diaceratherium lemanense*. This is an extinct genus of rhinocerotid from the Oligocene and Miocene of Eurasia.

Fig. 27. *Megatherium americanum* (giant sloth) was a slow-moving herbivore, feeding mainly on leaves and branches found in Argentina.

Fig. 28. The ‘*Palaeotherium* de mormoiron’, likely *Palaeotherium magnum*, found in the Mormoiron Basin in France. *Palaeotherium* was an extinct genus of horse-like, plant-eating mammals that lived in Europe from the Eocene to the Oligocene.

Ice age mammals: these include: a near-complete skeleton of Mammuthus primigenius (woolly mammoth) with tusks intact tougher with Mammuthus meridionalis, which is an earlier, larger species. There is also a woolly rhinoceros (Coelodonta antiquitatis), displayed alongside the mammoths to illustrate Pleistocene fauna.Note also the Irish elk (Megaloceras giganteus; Fig. 29).

Fig. 29. *Megaloceras giganteus* or Irish elk, but was neither confined to Ireland nor closely related to modern elk. This impressive species is best known for its enormous antlers – spanning up to 3. metres – which were shed and regrown annually.

These specimens are invaluable for understanding Pleistocene megafauna and their adaptations to Ice Age environments.

Other prehistoric elephants: On display is a skeleton of the massive and rarely displayed straight-tusked elephant, Palaeoloxodon antiquus.

Birds and flying reptiles

There are pterosaur remains, including large wingspans of Pteranodon and Rhamphorhynchus. And the early bird fossils include casts of Archaeopteryx and Confuciusornis, used for evolutionary comparison. There are also ostrich and moa skeletons showing gigantism in flightless birds (Figs. 30 and 31).

Fossil fish and marine life

There is also ?lagerstätten material from the Monte Bolca Eocene site in Italy (not far from Verona, interestingly). These include exquisite fish fossils with skin and fin detail, together with Devonian lobe-finned fish (relatives of the coelacanth) showing the evolution of limbs, and Cretaceous sharks and rays, often displayed in slabs to show skeletal outlines.

Invertebrate fossils

These are often overlooked, but they’re scientifically rich. There are classic trilobite specimens from Morocco, Bohemia and Brittany. And there are ammonites (Figs. 35 to 47), including enormous Jurassic and Cretaceous examples, often in polished cross-section and belemnites (Fig. 34), a gallery of which is set out below.

And there are crinoids and corals from French limestones, some mounted as full reef sections. Look out also for the brachiopods and molluscs illustrating marine biodiversity through time.

And on land, look out for the insect fossils from Oligocene and Miocene deposits (for example, the Aix-en-Provence shales) and arachnid fossils from the Carboniferous (Figs. 48 and 49).

Fig. 49. *Megarachne servinei* from the Upper Carboniferous of Argentina.Given its size, this is an arachnophobe’s worst nightmare.

There are also the arthropods, including a cast of the Silurian eurypterid, Mixopteris kiari (Fig. 50), an extinct genus of decapod crustacean (Fig. 51) and an extinct species of sea scorpions (Fig. 52).

Fig. 50. A cast of the Silurian eurypterid, *Mixopteris kiari*, from Norway.

Fig. 51. *Cycleryon propinquus*. *Cycleryon* is an extinct genus of decapod crustaceans and this is the type species. These epifaunal carnivores lived during the Late Jurassic (Kimmeridgian-Tithonian) of Germany and France.

Fig. 52. *Eurypterus lacustris*, an extinct species of eurypterid, commonly called ‘sea scorpions’.

Plant fossils

I was particularly impressed by the fossil ferns and cycads from the Carboniferous (Figs. 53 to 55) and Permian (Figs. 56 and 57), including material from the famous Autun and Commentry coal basins.

Fig. 53. *Annularia* sp, from the Upper Carboniferous. The name *Annularia* is applied to fossil foliage belonging to extinct plants of the genus *Calamites*, which is a relative of the horsetails (order Equisetales).

Fig. 54. *Neuropteris speciosa*, which is a seed fern from the Carboniferous.

Fig. 55. *Pectoperis* sp is a very common form genus of leaves. Most *Pecopteris* leaves and fronds are associated with the marattialean tree fern *Psaronius* (see Fig. 56).

Fig. 56. A cross section of *Psaronius brasiliensis* from the Permian of Brazil. *Psaronius* is an extinct genus marattialean tree fern which grew to 10m in height.

Fig. 57. *Walchia schlotheimii* from the Permian of Lodève in Southern France. Walchia is a primitive fossil conifer found in Upper Carboniferous and lower Permian rocks of Europe and North America.

And much later in time are the leaf impressions and petrified woods from the Tertiary of southern France (Figs. 58 to 60).

Fig. 58. *Flabellaria lamanonis* from the Miocene for France. It is an extinct fan palm, found in locations like the Isle of Wight and Paris.

Fig. 60. *Pinus resurgens*. This is a fossil species of pine tree that was first described in 1865 from specimens found in the Oligocene deposits of Armissan, France.

There are also plants from the Cretaceous (Fig. 61 and 62).

Fig. 61 *Araliopsoides cretacea* of the Cenomonian (Upper Cretaceous) of Kansas. *Araliopsoides* is an extinct genus of flowering plants in the family Araliaceae, known from the Cretaceous of North America, Siberia and Eastern Europe.

Fig. 62. *Glyptostrobus europaeus* is an extinct conifer species of the family Cupressaceae, which is found as fossils throughout the Northern Hemisphere, from the Early Cretaceous (Aptian).

There is even a fragment of the Rynie Chert from the Devonian Lagerstätten of Scotland (Fig. 63) and other Devonian specimens (Fig. 64).

Fig. 63. A fragment of Rhynie chert. The Rhynie chert is a Lower Devonian sedimentary deposit (and Lagerstätte) exhibiting extraordinary fossil detail. It is exposed near the village of Rhynie, in Scotland. It contains exceptionally preserved plant, fungus, lichen and animal material preserved in place by an overlying volcanic deposit.

Fig. 64. *Archaeopteris* sp is an extinct genus of progymnosperm tree with fern-like leaves. In the nineteenth and early twentieth centuries, palaeobotanists noticed that the same *Archaeopteris* species (and other Devonian and Carboniferous plants) appeared in regions now separated by oceans. Alfred Wegener (1912) used this as evidence for his theory of continental drift (later plate tectonics).

While not as extensive as the fossil vertebrates, these show the parallel evolution of terrestrial flora alongside vertebrate faunas.

Final thoughts

The Galerie’s fossil collection is a monument to French palaeontology’s golden age – Cuvier, Blainville, Lapparent, Gaudry and others. You’ll see the skeletons that defined the very idea of comparative anatomy, dinosaurs and mammals that shaped early evolutionary theory, and fossils from France’s own rich geological record and its nineteenth-century colonial expeditions.

Unlike some modern museums that hide fossils behind screens or multimedia, this one displays the bones directly – ranks of skeletons under daylight, like a secular cathedral to life’s history. That’s what I like.

Note that while many exhibits have labels in French, some may not have English translations. Using a translation app or guidebook can enhance your experience.

Lighting is natural, so the best viewing time is mid-morning or mid-afternoon when sunlight comes through the clerestory windows. Photography is generally allowed, but be mindful of lighting and reflections when capturing specimens. In fact, the lighting could be improved and is certainly not good for taking photos. To avoid crowds, consider visiting early in the day or on weekdays.

So, in conclusion, this is a museum you must visit if you like palaeontology and have a spare few hours in the French capital.
