PETROGLYPHS

Oct. 20, 2018

In October 2018, petroglyphs were discovered in the Ratnagiri and Rajapur areas in the Konkan region of Maharashtra. Those rock carvings which might date back to 10,000 BC, depict animals like hippopotamuses and rhinoceroses which aren't found in that region of India.

Petroglyphs:

Petroglyphs are images created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art.
Scholars often use terms such as "carving", "engraving" to refer such images.
Petroglyphs are found worldwide, and are often associated with prehistoric peoples.

Petroglyph vs Petrograph vs Petroforms:

The term petroglyph should not be confused with Petrograph and Petroforms.
Petrograph is an image drawn or painted on a rock face.
Petroforms are patterns and shapes made by many large rocks and boulders over the ground.
