Taxonomy
Ihlengesi changoensis was named by Bianucci et al. (2023). Its type specimen is MUAP(MM)-068, a partial skull (partial cranium including the complete rostrum, the medial facial area (premaxillary sac fossae and vertex) and part of both supraorbital regions.), and it is a 3D body fossil. Its type locality is Pisagua, off the port of, which is in a Pliocene/Pleistocene offshore horizon in Chile.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. Bianucci et al. 2023 | Ihlengesi changoensis sp. nov. differs from Ihlengesi saldanhae in the following characters: more elon- gated premaxillary sac fossa and consequently premaxillary foramen more anteriorly located (ratio between the longi- tudinal distance between the right premaxillary foramen and the rostrum base and the width of rostrum base equals 0.10 contra 0.32 in I. saldanhae); dorsal margin of each premaxillary crest sloping markedly ventrolaterally and generating an acute dorsal profile of the vertex in anterior view (rounded profile in I. saldanhae); less anterolateral extension of the right nasal forming part of the premaxillary crest; lateral margins of the nasals not anteriorly diverging but weakly convex; nasofrontal suture not convex posteri- orly but anteriorly pointed. |
