Answer 1

DECANTRAP

The Deccan Traps are a large igneous province located on the Deccan Plateau of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth. They consist of multiple layers of solidified flood basalt that together are more than 2,000 m (6,600 ft) thick, cover an area of c. 500,000 km2 (200,000 sq mi),[1] and have a volume of c. 1,000,000 km3 (200,000 cu mi).[2] Originally, the Deccan Traps may have covered c. 1,500,000 km2 (600,000 sq mi),[3] with a correspondingly larger original volume.

Answer 2

Answer:Fossils

The Deccan Traps are famous for the beds of fossils that have been found between layers of lava. Particularly well known species include the frog Oxyglossus pusillus (Owen) of the Eocene of India and the toothed frog Indobatrachus, an early lineage of modern frogs, which is now placed in the Australian family Myobatrachidae.[17][18] The Infratrappean Beds and Intertrappean Beds also contain fossil freshwater molluscs.[19]
