Velociraptor

Lore & Background

The first Velociraptor fossil known to science—a crushed but complete skull, associated with one manual claw and adjoining phalanges—was discovered by Peter Kaisen on 11 August 1923 during an American Museum of Natural History expedition to the Flaming Cliffs of the Djadochta Formation, Gobi Desert. In 1924, Henry Fairfield Osborn designated the skull and part of the manus as the type specimen of the new genus Velociraptor. Osborn named the type species V. mongoliensis after its country of origin. Earlier that year, Osborn had informally mentioned the animal in a popular press article under the name 'Ovoraptor djadochtari', eventually changed into V. mongoliensis during its formal description. The most famous specimen is part of the 'Fighting Dinosaurs' specimen (MPC-D 100/25), discovered by a Polish-Mongolian team in 1971, which preserves a Velociraptor in battle against a Protoceratops.

Reader's Guide

Velociraptor can be distinguished from other dromaeosaurids by its long and low skull, with an upturned snout. Prominent quill knobs have been reported from the ulna of a single Velociraptor specimen (IGM 100/981), indicating feathers, though the specimen number has been corrected to IGM 100/3503 and its referral to Velociraptor may require reevaluation. Velociraptor is one of the dinosaur genera most familiar to the general public due to its prominent role in the Jurassic Park films. In reality, Velociraptor was roughly the size of a turkey, considerably smaller than the approximately 2 m long and 90 kg reptiles seen in the novels and films (which were based on members of the related genus Deinonychus).

Did You Know?

• Velociraptor is derived from Latin words meaning 'swift robber' or 'swift plunderer', referring to its cursorial nature and carnivorous diet.
• One particularly famous specimen preserves a Velociraptor locked in combat with a Protoceratops, considered a national treasure of Mongolia.
• A possible record of Velociraptor is known from the Nemegt Formation.
• The species V. osmolskae might not actually belong to the genus Velociraptor and requires reassessment, according to a 2013 study.

Discovery in the Gobi

On August 3, at the Tugriken Shire locality within the Djadokhta Formation, researchers Tomasz Jerzykiewicz, Maciej Kuczyński, Teresa Maryańska, Edward Miranowski, Altangerel Perle, and Wojciech Skarżyński uncovered a sedimentary block containing two animals locked together in what appeared to be a fatal struggle. The specimen was first spotted because fragments of a Protoceratops skull lay overlapping the surface sediments, drawing the team's attention to the excavation site. Once freed from the rock, the pose was unmistakable: a Velociraptor mongoliensis and a Protoceratops andrewsi preserved mid-combat. The pair was immediately nicknamed the Fighting Dinosaurs.

Geological Setting and Age

Pinpointing the exact age of the Fighting Dinosaurs has proven more challenging than one might expect. The Djadokhta Formation, a sedimentary unit rich in fossils, lacks the ideal stratigraphic sections and plant fossils needed to correlate it cleanly with neighboring geological units. In 2005, Demberelyin Dashzeveg and colleagues addressed this by splitting the formation into two members: the older Bayn Dzak Member below and the younger Turgrugyin Member above, both sharing broadly similar depositional environments. The Tugriken Shire locality where the pair was found falls within the Turgrugyin Member. Using magnetostratigraphic techniques applied to sediments from both the Bayn Dzak and Tugriken Shire sites, the team established that the formation accumulated roughly between 75 and 71 million years ago, placing it squarely in the Campanian stage of the Late Cretaceous. This means the two dinosaurs locked in their final struggle lived during a period when the Gobi region was a vast, sediment-rich landscape, and their bones were ultimately entombed in the fine-grained deposits that would preserve them for millennia.

Competing Theories of Death and Burial

Since its excavation, paleontologists have proposed several competing explanations for how both animals ended up preserved together. They observed the Velociraptor's right hand caught in the prey's jaws, its left clawing at the skull, and its feet aimed at the throat. Unwin's team concluded a sandstorm buried the pair alive and that the raptor dispatched its prey with kicks. Kenneth Carpenter offered a different scenario in 1998: the sickle claw served as a piercing tool, inflicting throat wounds that bled the Protoceratops to death. In its last act, the prey clamped its jaws around the predator's right hand, holding it fast beneath its body until the Velociraptor desiccated. Both were then covered by sandy sediments, and the raptor's missing limbs were later removed by scavengers.

Legacy and Ongoing Research

The Fighting Dinosaurs occupies a singular place in paleontological history as one of the few specimens offering direct, unambiguous evidence that non-avian theropods were active predators rather than mere scavengers. Yet the specimen continues to yield new information. In 2016, Barsbold reported anomalies in the Protoceratops individual, including small bone fragments in both coracoids indicating a broken pectoral girdle, and the right forelimb and scapulocoracoid displaced sharply to the left and rearward relative to the torso. He interpreted this prominent displacement as the result of an external force attempting to tear those elements free. These findings keep the specimen at the center of debate, reminding researchers that even a fossil preserved for over seventy million years can still surprise us with new details about the events of its final moments.

Common Misconceptions (Editorial)

Many people believe Velociraptor was a large, man-sized predator, but it was actually roughly the size of a turkey. Another common misconception is that the name “Ovoraptor djadochtari” was an official early name for the genus; in reality, it was a nomen nudum and never formally published, so V. mongoliensis and V. osmolskae are the only valid species.

Why It Matters (Editorial)

Velociraptor endures in the public imagination not because of its actual size, but because it embodies the tension between scientific discovery and popular culture. Its famous “Fighting Dinosaurs” fossil—locked in combat with a Protoceratops—offers a rare, dramatic snapshot of prehistoric life, reminding us that even small predators played fierce roles in ancient ecosystems.
