Scientists have discovered the fossil of a Jurassic Period dinosaur, known as Fujianvenator prodigiosus, in Fujian Province. This find is crucial in understanding the evolutionary stage that led to the origin of birds. Fujianvenator belongs to the avialans group, which includes all birds and their closest non-avian dinosaur relatives. Although the fossil is mostly intact, it lacks the skull and parts of the feet, making it challenging to deduce its diet and lifestyle. Notable features include a disproportionately long lower leg bone (tibia), a bird-like forelimb with three claws on its fingers, and a long bony tail. While it cannot be confirmed if Fujianvenator could fly, it’s likely that it had feathers, given its close relatives. This discovery contributes to our understanding of the bird’s origins and the transition from non-avian dinosaurs to birds.
Facts/Terms for UPSC Prelims
- Avialans: A group of dinosaurs that includes all birds and their closest non-avian dinosaur relatives, such as Fujianvenator prodigiosus.
- Theropods: A group of bipedal, carnivorous dinosaurs to which Fujianvenator belongs. They are known for their two-legged stance and are thought to be the ancestors of modern birds.
- Archaeopteryx: The oldest-known bird, dating back approximately 150 million years ago in Germany. It played a significant role in understanding the evolutionary link between dinosaurs and birds.
- Fossils Shortage: Refers to the limited availability of fossils from the earliest stages of bird evolution, making it challenging for scientists to fully comprehend the history of birds and their transition from non-avian dinosaurs.
- Bird-Like Traits: Features and characteristics in non-avian dinosaurs that are similar to those of modern birds, providing valuable insights into the evolutionary process that led to the development of avian species.
