Velociraptor

life science Maturity 5-7 Next article →

The *Velociraptor* is a genus of small dromaeosaurid dinosaurs. These animals lived in Asia during the Late Cretaceous epoch. This period occurred approximately 75 million to 71 million years ago.

While many people know them from movies, the real animals were quite different. In films, they appear as large, tall reptiles. In reality, a *Velociraptor* was roughly the size of a turkey. They were bipedal carnivores, meaning they walked on two legs and ate meat.

They were covered in feathers and possessed long tails.

Anatomy defines how the *Velociraptor* functioned in its environment. They were smaller than other dromaeosaurids like *Deinonychus* or *Achillobator*. However, they shared many anatomical features with those larger relatives. One key feature was an enlarged, sickle-shaped claw on each hindfoot.

Scientists believe this claw helped them tackle and restrain prey. Their bodies were built for movement, and their long tails helped with balance. They also possessed quill knobs on their ulna, which are attachment sites for feathers. These knobs suggest they had large "wing" feathers stemming from the forearm.

The skull of a *Velociraptor* is very distinct from other dinosaurs. It was long and low with a uniquely up-curved snout. This snout occupied about 60% of the entire skull length.

The snout was narrow and formed by the nasal, premaxilla, and maxilla bones. The maxilla, or the main tooth-bearing bone of the upper jaw, had a central depression. This depression contained a small hole called a maxillary fenestra. The skull also featured a large, nearly circular eye socket, or orbit. These specialized structures helped paleontologists identify the genus.

History shows how scientists slowly pieced this animal together. On August 11, 1923, Peter Kaisen discovered the first known fossil. He found a crushed but complete skull in the Gobi Desert. This discovery happened during an American Museum of Natural History expedition.

In 1924, Henry Fairfield Osborn named the genus *Velociraptor*. The name comes from Latin words meaning "swift robber." He named the type species *V. mongoliensis* after its home in Mongolia. This species was first described using fossils from the Djadochta Formation.

Many different species and specimens have been identified over time. The most famous is the "Fighting Dinosaurs" specimen. A Polish-Mongolian team discovered this in 1971.

It shows a *Velociraptor* locked in combat with a *Protoceratops*. This fossil is considered a national treasure of Mongolia. Other species include *V. osmolskae*, found in China's Bayan Mandahu Formation. More recently, in 2021, a specimen named *Shri devi* was identified.

Some scientists even suggest a third species exists based on skull shape.

Finding these fossils requires looking at many specific parts of the bone. For example, the maxilla can tell scientists if a specimen is a new species. In 2020, researcher Mark J. Powers used morphometric analyses to study these bones. He argued that certain specimens had a shallow maxilla morphology. This suggested they were ecologically separated from *V. mongoliensis*.

Such detailed studies help us understand how different species lived in the same area. Even small differences in the hindlimbs or skull can indicate a unique animal.

Studying the *Velociraptor* connects us to the broader history of life on Earth. It helps paleontologists understand the evolution of dromaeosaurids. By comparing them to larger relatives, we see the diversity of this group.

Their feathers link them to the study of bird evolution. The way they hunted and moved provides clues about ancient ecosystems. Every fossil, from a single tooth to a complete skeleton, adds to the puzzle. These discoveries allow us to reconstruct a world that existed millions of years ago.
