Q. “Arackar licanantay” is recently seen in news is related to which of the following?
Scientists studying Chile’s parched Atacama desert, the world’s driest, have discovered the remains of a previously unknown species of dinosaur that millions of years ago lived among lush greenery in what is now a moonscape of rock and sand.
- A team led by Chilean geologist Carlos Arévalo unearthed the remains of Arackar licanantay, which means “Atacama bones” in the Kunza language, 75 kilometers south of the desert city of Copiapó.
- The so-called titanosaur had a small head and long neck and tail, as well as an unusually flat back compared with others like it.
- Recent paleontological studies suggest Arackar lived amid flowering plants, ferns and palm trees during the Cretaceous period 66-80 million years ago.
- Parts of the Atacama today, by contrast, have gone without rain for one hundred years and support little plant or animal life.
- The discovery of a titanosaur on the west side of South America’s Andes Mountains is rare, though several species have been found in Argentina and Brazil, further east.
- Arackar also appears smaller in size compared with some other titanosaurs.
- The Argentinosaurus, discovered on the east side of the Andes in neighbouring Argentina, was more than four times as long, scientists say.
