Nalacetus is known mostly from dental remains from the Lutetian of the Kala Chitta Hill, Punjab, Pakistan:[3]
H-GSP[Explain 1] 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.[3]
