When: Panandhro Formation, Lutetian (47.8 - 41.3 Ma)
• "..snake bearing silty shales form part of the Panandhro Formation of Saraswati & Banerjee (1984) or its broadly correlatable unit designated as Naredi Formation by Biswas (1992) (pg. 696)."
•Our previous age inference for these beds (Bajpai and Thewissen, 2002) was based on the traditional inclusion of them in the Naredi Formation, which followed Biswas (1992). Biswas (1992) considered the Naredi Formation to range from late Paleocene to early Eocene in age. While this age estimate may be reasonable at the type section of the formation (where there is neither lignite nor fossil cetaceans), it appears that this is not the case at Panandhro and Akri Lignite Mines. Here, the stratigraphy is more complex and the beds yielding the whales are best included in the Panandhro Formation of Saraswati and Banerjee (1984, preferred here) or the Lakhpat Formation of Mukhopadhyay and Shome (1996). These beds are equivalent in age to the Harudi Formation: middle/late Lutetian. The Domanda Formation of central Pakistan is also Lutetian in age (Gingerich et al., 2001a).
