Kind: research · Impact: low

## In brief

- A fossil pygmy sperm whale skull from southern Peru's Pisco Formation is highly asymmetric.
- The skull was found in the mid-1990s and was examined in 2015 by Aldo Benites-Palomino during his bachelor's thesis at the Museo de Historia Natural in Lima.
- The find might hold the record for the most lopsided face of any mammal recorded.

## Why it matters

It documents an unusually lopsided skull in a fossil toothed whale, which is relevant to research on cetacean skull anatomy and evolution.
