Bizarre’ bird-like dinosaur has scientists enthralled
Subject: Environment
Section: Species in news
Context:
- Scientists said on September 6 they unearthed in Fujian Province the fossil of a Jurassic Period dinosaur they named Fujianvenator prodigiosus – a creature that sheds light on a critical evolutionary stage in the origin of birds.
Details:
- A pheasant-sized and bird-like dinosaur with elongated legs and arms (like wings) inhabited southern China about 140-150 million years ago. The anatomy indicated that it either was a fast runner or a wader (shorebird) bird.
- Around 150 million years ago in Germany, the oldest known bird Archaeopteryx- a crow-sized bird with teeth, a long bony tail, and no beak- rose from a lineage in late Jurassic period, of small feathered two-legged dinosaurs known as Theropods.
- Birds survived the asteroid strike 66 million years ago that doomed their non-avian dinosaur comrades.
Fujianventor prodigiosus:
- Member of a grouping called avialans that includes all birds and their closest non-avian dinosaur relatives.
- The fossil is fairly complete but lacks the animal’s skull and parts of its feet, making it hard to interpret its diet and lifestyle.
- Fujianvenator’s lower leg bone – the tibia – was twice as long as its thigh bone – the femur. Such dimensions are unique among theropods; it also had a long bony tail.
- The forelimb is built like a bird’s wing, but with three claws on the fingers, which are absent from modern birds. So it can be called a wing but it is impossible to determine whether it could fly or not.
