Nalacetus

Nalacetus is an extinct pakicetid early whale, fossils of which have been found in Lutetian red beds in Punjab, Pakistan. Nalacetus lived in a fresh water environment, was amphibious, and carnivorous. It was considered monophyletic by.
It was said to be wolf-sized and one of the earliest forms of the order Cetacea.
Nalacetus is known mostly from dental remains from the Lutetian of the Kala [Chitta Range|Kala Chitta Hill], Punjab, Pakistan:

H-GSP 96055, right palatal fragment with P⁴ and M¹⁻².
H-GSP 30306, right maxillary fragment with P² and partial P³⁻⁴; a fragmentary mandible with fragmented teeth together with some isolated lower teeth.

In the cheek teeth of Pakicetus, the protocone lobe increases from the first molar to the third. In Nalacetus, in contrast, the protocone lobe is larger in the first molar than in the second.
