  • The story: A 66-million-year-old dinosaur embryo was discovered in Ganzhou in southern China. It is believed to be a toothless theropod dinosaur, or oviraptorosaur, and was named Baby Yingliang. The discovery provided researchers a greater understanding of the link between dinosaurs and modern birds. The fossil showed an embryo in a curled position called “tucking”. This is seen among birds, shortly before they hatch. It indicates that tucking behaviour in modern birds has been evolved and originated from their dinosaur ancestors. Interestingly, 66 m y.a. is the time when the giant asteroid strike obliterated dinosaurs from planet earth.
  • Oviraptorosaurs: It means “egg thief lizards”. They were feathered dinosaurs, that lived-in present-day Asia and North America during Late Cretaceous period, some 100 million to 66 million years ago. They are distinct for their short, beaked, parrot-like skulls.
  • Baby Yingliang: This measures 27cm long from head to tail. It is resting inside a 6.7-inch-long egg at Yingliang Stone Nature History Museum in China. This egg was first uncovered in 2000 and put into storage for 10 years.
  • About Theropoda Clade: Members of Theropoda clade are known as theropods. Teropoda is a dinosaur clade, characterized by hollow bones as well as three-toed limbs. Theropods are usually classed as a group of saurischian dinosaurs. They were ancestrally carnivorous. However, a number of theropod groups evolved to become omnivores, herbivores, piscivores, and insectivores. They first appeared during Carnian age in late Triassic period, around 231.4 million years ago. They included all the large terrestrial carnivores, from Early Jurassic to Cretaceous period.
  • EXAM QUESTIONS: (1) Explain the insights science gets when entire samples of fossilised dinosaur eggs are found. (2) What are the ways dinosaurs dominated planet Earth for 15 crore years, before one rock obliterated them?
