Kala Chitta Range

Kala Chitta Range (in Punjabi and Urdu: کالا چٹا Kālā Chiṭṭā) is a mountain range in the Attock District of Punjab, Pakistan. "Kala" and "Chitta" are Punjabi words, meaning "black" and "white", respectively. The range thrusts eastward across the Potohar plateau towards Rawalpindi.

Pakistan's Kuldana Formation is best known for its fossil Eocene mammals, including primitive cetaceans such as Pakicetus, Ambulocetus and Attockicetus. Kuldana mammals have been considered in different studies as coming from the early Lutetian (early Middle Eocene), late Ypresian (late early Eocene) or, more recently, encompassing much of Ypresian up to early Lutetian time (early part of the early Eocene to early Eocene medium).
