New Velociraptor-Like Dinosaur with Four Wings Discovered Preying on Birds

Text
A newly identified dinosaur species, Jianchangmensis, has been discovered in China, according to multiple Indonesian news outlets including VOI.id and Kompas.com. The fossil, dated to approximately 120 million years ago, exhibits features resembling both Velociraptors and birds, suggesting it may have been a tree-dwelling predator that hunted avian species. The findings, reported by Sains – Terbaru – Google Berita on June 11, 2026, add to ongoing debates about the evolutionary link between non-avian dinosaurs and modern birds.

What is Jianchangmensis?
The fossil, described as a four-winged predator, was unearthed in the Xinjiang region of China. Researchers note its elongated forelimbs and hind limbs, which show adaptations for gliding or climbing trees. Media Indonesia reported that the creature’s skeletal structure resembles that of Velociraptor, a small theropod dinosaur known for its agility. However, Jianchangmensis differs in having feathered limbs on both its arms and legs, a trait observed in other theropods like Microraptor.

According to VOI.id, the discovery challenges previous assumptions about the ecological roles of small theropods. The fossil’s teeth and jaw structure indicate it likely targeted small vertebrates, including early birds. Kompas.com cited paleontologists suggesting the dinosaur may have launched itself from trees to ambush prey, a behavior previously associated with arboreal mammals. This hypothesis aligns with findings from other four-winged dinosaurs, such as Yixianosaurus, which also show tree-dwelling adaptations.

How Does This Discovery Impact Paleontology?
The study of Jianchangmensis provides new insights into the transition from non-avian dinosaurs to birds. Researchers at the Chinese Academy of Sciences, quoted by Validnews, emphasized that the fossil’s feathered limbs and gliding capabilities support the theory that flight evolved through a "tree-down" model, where dinosaurs developed aerial abilities before transitioning to ground-based movement. This contrasts with the "ground-up" hypothesis, which posits that flight emerged from running bipedal ancestors.

The discovery also highlights the diversity of theropod adaptations during the Early Cretaceous period. Harapan Rakyat noted that Jianchangmensis shares similarities with Anchiornis, another feathered dinosaur, but differs in its larger size and predatory morphology. Scientists are now analyzing the fossil’s microstructure to determine the function of its feathers, which could reveal whether they served for insulation, display, or aerodynamics.

What Are the Broader Implications?
The findings contribute to ongoing research on dinosaur-bird evolution, a field where new fossils frequently reshape scientific understanding. A 2023 study published in Nature analyzed 120 million-year-old feathered dinosaurs and found evidence of complex flight mechanics in several species. Jianchangmensis may represent a transitional form between gliding and powered flight, according to Dr. Li Wen, a paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology.

The discovery also raises questions about the ecological interactions of the Early Cretaceous. Kompas.com reported that Jianchangmensis lived alongside early birds like Eoenantiornis, which lacked the ability to fly long distances. This suggests a predator-prey dynamic where tree-dwelling dinosaurs like Jianchangmensis could have influenced the evolution of avian escape strategies.

What Comes Next for the Research?
Paleontologists plan to conduct further excavations in the Xinjiang region, where similar fossils have been found. The team, led by Dr. Zhang Wei, aims to uncover more specimens to better understand the species’ behavior and habitat. Additionally, 3D modeling of the fossil’s skeleton will help simulate its movement, providing data on how it might have navigated forest canopies.

The study of Jianchangmensis underscores the importance of continued fossil exploration in China, which has become a hotspot for dinosaur research. Over the past decade, the country has yielded thousands of well-preserved specimens, including the first known feathered theropods. As new technologies like synchrotron imaging and DNA analysis advance, scientists hope to extract more details about the lives of these ancient creatures.

Quoted text
"Every new fossil adds a piece to the puzzle of how dinosaurs evolved into birds," said Dr. Zhang Wei, according to Harapan Rakyat. "This discovery highlights the complexity of their ecosystems and the adaptability of these species."

The findings are expected to be published in a peer-reviewed journal later this year, pending further analysis. Until then, the fossil remains on display at the Xinjiang Geological Museum, where researchers and the public can examine its unique features.

Why This Matters to Science and Society
The discovery of Jianchangmensis reinforces the idea that dinosaurs were not just large, land-based predators but also capable of complex behaviors like arboreal navigation. For educators and science communicators, the fossil serves as a tangible example of evolutionary transitions, making abstract concepts like natural selection more accessible.

For the broader public, the find captures the imagination by blending elements of myth and science. The four-winged predator evokes comparisons to mythical creatures like dragons, yet its existence is grounded in rigorous paleontological research. As Dr. Li Wen noted, "This is a reminder that the line between fiction and reality in paleontology is often blurred, but the evidence speaks for itself."
