Brussels, Paris, Berlin, Madrid: the skylines of the great EU capitals teem with glass and steel, but deep beneath these modern capitals lies a story older than civilisation itself — the slow accumulation of bone, silt and time that birthed the dinosaurs.
Across what is now the European Union, palaeontological discoveries reveal a continent once roamed by creatures as diverse and remarkable as the cities that occupy those landscapes today. What follows is an exploration of dinosaur bones and fossils in the EU, and a speculative look at which species might have hunted, grazed or thundered across the very soils where Europe’s capitals now stand.
Long before Brussels became a political hub, the region was home to giants. In the late 19th century, coal miners in the Sainte-Barbe clays near Bernissart, deep beneath Belgium’s soil, encountered something extraordinary. At 322 metres underground they unearthed dozens of Iguanodon skeletons — herbivores of the Early Cretaceous, characterised by their thumb spikes and formidable bulk. Around thirty of these Iguanodon bernissartensis individuals were eventually excavated, preserved, and later mounted in museums, offering a vivid glimpse into a prehistoric ecosystem that existed roughly 125 million years ago.
Yet Belgium is not alone in this ancient narrative. Further south, in the rolling landscapes of western France, the Angeac-Charente bonebed has yielded one of the most diverse assemblages of Early Cretaceous vertebrates known in Europe. Bones unearthed here include large femora that may belong to sauropods — long-necked behemoths that dwarfed even the mighty Iguanodon — alongside remains of other dinosaurs that once plied these floodplain environments.
France’s fossil record extends across the Mesozoic, from Late Triassic reptiles preserved in the Jura to dinosaur tracks and bone fragments in Provence and Languedoc, suggesting a rich tapestry of creatures over tens of millions of years.
As one’s gaze shifts east, the story deepens. Germany, though less prolific in large, articulated skeletons, is a cornerstone of early dinosaur research. It was in Bavaria and the surrounding regions where Plateosaurus, one of Europe’s earliest and most abundant dinosaurs, was first identified. More than 250 fossils of this Triassic herbivore have been collected across Germany, Switzerland, and France, making it emblematic of an era when primitive sauropodomorphs ranged widely across the European archipelago that then existed.
These finds are reminders that the continent’s geology was once dramatically different. During the Mesozoic, Europe was not one contiguous landmass but a mosaic of islands and shallow seas teeming with life. Over time, tectonic shifts and sea-level changes submerged and uplifted these landscapes, leaving behind fossil-rich formations that today lie beneath cities and countrysides alike.
It is tempting to speculate, with no small degree of romanticism, about what types of dinosaurs might have traversed the exact ground where Europe’s capitals now stand.
Brussels
Under present-day Brussels, the Bernissart Iguanodons suggest an environment once dominated by marshy plains and lush vegetation. It is not fanciful to imagine herds of Iguanodon bending to graze amidst conifer forests where the Royal Quarter now stands, their footsteps eventually fossilised in the clays that would one day conceal them.
Paris
Paris, perched on the Seine, is surrounded by sedimentary basins that have yielded dinosaur footprints and skeletal fragments in the wider Île-de-France region. While no major skeleton has yet been unearthed in the city’s heart, the nearby Angeac-Charente discoveries hint that sauropods and large ornithopods might once have ambled through riverine forests around where the Louvre now stands.
Berlin
Berlin and its environs — though largely post-glacial in their visible geology — are not far from sites in Saxony-Anhalt and Baden-Württemberg where Plateosaurus remains have been found. One might imagine these early dinosaurs grazing along floodplain corridors that prefigure the Spree river valley, their bones ultimately buried as river channels shifted and sediments accumulated.
Madrid
In Spain, rich Cretaceous deposits in regions like the Teruel Basin and the Tremp Formation have produced remains of European sauropods and hadrosaurids. Had Madrid’s Roman foundations been laid atop the ancient floodplains of the Ibero-Armorican island, it’s plausible that species akin to Abditosaurus and other late Cretaceous giants once roamed near where the Palacio Real now dominates.
Across the EU’s tapestry, the fossil record offers not only fragments of bone but threads of continuity between prehistoric life and modern society. Whether in the coal seams beneath Belgium or the clay beds of France, these remains testify to a world transformed — from land of dinosaurs to capitals of statecraft. And though the beasts themselves have long vanished, their echoes persist in the scientific discoveries that continue to reshape our understanding of Europe’s deep past.
