Rajmahal Hills

Rajmahal Hills are hills formed from rocks dating from the Jurassic Period and named after the town of Rajmahal which lies to the east in the state of Jharkhand in India. 

• The hills are oriented in a north-south axis with an average elevation of 200–300 m (600-1,000 ft). 
• The River Ganga meanders around the hills changing direction of flow from eastwards to southwards. Volcanic activity in the Jurassic caused the formation of these hills. 
• The upper regions of the Rajmahal Hills are inhabited by the Sauria Paharia tribe while the valleys are dominated by the Santhal tribe who cultivate the land. 
• The ancient plant fossil formations of Rajmahal and Mandro in Sahebganj district have been given the 'geological heritage site' status by the Geological Survey of India (GSI). This is to preserve the area from rampant excavation.
  
  
  
• The Rajmahal hill range is believed to be one of the oldest mountain range and finest Jurassic-era fossil beds in the world.
