Fujianvenator Prodigiosus UPSC NOTE

 

Fujianvenator prodigiosus

  • About 148 to 150 million years ago, a strange pheasant-sized and bird-like dinosaur with elongated legs and arms built much like wings inhabited southeastern China, with a puzzling anatomy suggesting it either was a fast runner or lived a lifestyle like a modern wading bird.

Recently in news

  • Scientists said on 6th September 2023, they have 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.

  • A remarkable event in dinosaur evolution came when small feathered two-legged dinosaurs from a lineage known as theropods gave rise to birds late in the Jurassic, with the oldest-known bird - Archaeopteryx - dating to roughly 150 million years ago in Germany.

  • Fujianvenator is a member of a grouping called avialans that includes all birds and their closest non-avian dinosaur relatives. 

  • Despite their modest beginnings, birds survived the asteroid strike 66 million years ago that doomed their non-avian dinosaur comrades.

  • The Fujianvenator fossil, discovered last October, 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 generally built like a bird’s wing, but with three claws on the fingers, which are absent from modern birds. So you can call it wing. It cannot be determined whether it could fly or not.

  • The fossil itself does not preserve feathers. However, its closest relatives and nearly all the known avialan theropods have feathers.
