Why in News?

  • Barsu sites in the Konkan region were added to a tentative list of UNESCO’s world heritage sites and protected by the state archaeology department and the Archaeological Survey of India (ASI).

What are geoglyphs?

  • Geoglyphs are a form of prehistoric rock art, created on the surface of laterite plateaus.
  • They are made by removing a part of the rock surface through an incision, picking, carving or abrading.
  • They can be in the form of rock paintings, etchings, cup marks and ring marks.

What is the significance of this prehistoric rock art?

  • Clusters of geoglyphs are spread across the Konkan coastline in Maharashtra and Goa, spanning around 900 km. Porous laterite rock, which lends itself to such carving, is found on a large scale across the entire region.
  • It has more than 1,500 pieces of such art, also called “Katal Shilpa,” spread across 70 sites.
  • This is evidence of the continued existence of human settlements from the Mesolithic (middle Stone Age) to the early historic era.
  • UNESCO’s tentative world heritage list mentions seven sites with petroglyphs in Ratnagiri district — Ukshi, Jambharun, Kasheli, Runde Tali, Devihsol, Barsu and Devache Gothane, one in Sindhudurg district –Kudopi village, and nine sites at Phansamal in Goa.
  • The figures depicted in the geoglyphs include humans and animals such as deer, elephant, tiger, monkey, wild boar, rhinoceros, hippopotamus, cattle, pig, rabbit, and monkey.
  • They also include a high number of reptilian and amphibian creatures such as tortoises and alligators, aquatic animals such as sharks and sting rays, and birds like peacocks.
