AN EXCEPTIONAL FOSSIL The Dubreuillosaurus Valesdunensis is one of the most significant paleontological discoveries made in France over the past thirty years. It is the only currently known specimen of its species and serves as its holotype. Discovered in 1994 in Conteville, in the Calvados region, this theropod—a bipedal carnivorous dinosaur belonging to the same major group as Allosaurus and Tyrannosaurus rex—lived approximately 167 million years ago. At that time, the site was a shallow coastal environment bordering a warm sea and close to the exposed land of the Armorican Massif, with vegetation interpreted as similar to a mangrove. Although a terrestrial animal, this dinosaur was preserved in marine sediments or in environments connected to the sea, such as lagoons, estuaries, or bays. In 2002, scientific research initially led Ronan Allain to describe a new species under the name Poekilopleuron valesdunensis. In 2005, after studying the postcranial skeleton, he transferred this species to a new genus, Dubreuillosaurus, created in honor of its discoverer, André Dubreuil (1941–2024). Today, this fossil—whose provenance is thoroughly documented—is poised to write a new chapter in its history. The specimen on display is the only one known to date; it is a holotype, the sole reference used to officially describe the species. Its provenance has been continuous and thoroughly documented from its discovery through to its display in the museum. The Dubreuillosaurus valesdunensis specimen is both a spectacular fossil and a subject of study that has profoundly enriched our understanding of European carnivorous dinosaurs of the Middle Jurassic. A DISCOVERY BORN OF CHANCE The story begins in late summer 1994, toward the end of September. In Conteville, in the Calvados department, André Dubreuil—a member of the Paleontological Association
