Vouivria is a genus of brachiosaurid sauropod dinosaur that lived during the Late Jurassic period, approximately 150 million years ago, in what is now eastern France. The type species, Vouivria damparisensis, was described in 2017 based on fossil material recovered from the middle Oxfordian (Upper Jurassic) strata near the town of Damparis in the Franche-Comté region.
Etymology
The generic name Vouivria derives from the French exclamation “vouivre” (a mythical dragon or serpent in regional folklore) combined with the suffix “-ria,” forming a name that evokes the creature’s presumed large, serpentine form. The specific epithet damparisensis references the locality of Damparis where the holotype specimen was discovered.
Discovery and Holotype
Fossils attributed to Vouivria were first uncovered in the late 19th century during quarrying activities at the Damparis site. The material remained largely undescribed until a reassessment in the 2010s, which identified a partial skeleton including vertebrae, limb elements, and fragments of the pelvis. The holotype, designated as MNHN.F.33243, is housed in the Muséum national d’Histoire naturelle (MNHN) in Paris. Additional referred material includes isolated teeth and caudal vertebrae from the same stratigraphic layer.
Geological Context
The fossils originate from the “Molasse du Jura” formation, specifically the middle Oxfordian stage of the Late Jurassic. This interval is characterized by floodplain deposits and overbank sediments, indicating a humid, subtropical environment with abundant vegetation.

Phylogenetic analyses place Vouivria within Brachiosauridae, closely related to Brachiosaurus and Giraffatitan, but retaining several primitive traits that illuminate early brachiosaurid evolution.
Morphology
Vouivria is estimated to have reached lengths of 15–20 meters and weighed roughly 15–20 tonnes. Diagnostic features include:
- Elongated cervical vertebrae with pronounced neural arches.
- Robust humeri with a distinctive deltopectoral crest.
- Dorsal vertebrae exhibiting opisthocoelous centra (convex anterior, concave posterior surfaces).
- Limb bone proportions indicative of a high browsing posture, typical of brachiosaurids.
The overall skeletal reconstruction suggests a quadrupedal herbivore with a columnar forelimb stance, allowing it to access vegetation at heights exceeding 10 meters.
Paleoecology
The Damparis locality likely supported a diverse assemblage of Jurassic fauna, including other sauropods, theropods, and early ornithischians. Plant fossils from the same strata indicate the presence of conifers, cycads, and fern-like flora, providing ample forage for large herbivores such as Vouivria.
Significance
The description of Vouivria has contributed to a refined understanding of brachiosaurid diversity in Europe during the Late Jurassic, a period previously dominated by North American and African taxa. Its mixture of derived and basal characteristics offers insight into the biogeographic dispersal and evolutionary pathways of Titanosauriform sauropods.
