Phiomicetus anubis is known from a partial skull and mandible with a large temporal fossa and large incisors, suggesting a greater bite force potential than other protocetids of the same size. It's also a surprisingly early diverging taxon to occur outside Indo-Pakistan:

@ASWolniewicz @Livvly @NHM_London @morethanadodo @AMNH @CarnegieMNH I concur with that - and @livvly, sperm whales are better than dinosaurs anyway. This tooth is from at least a 40 foot long predatory sperm whale, owing to how huge the tooth is. Livyatan (shown here) was about 60-70 feet long and adapted to eat other cetaceans:

in the SIXTH paper from my Ph.D. we reported a fragmentary specimen of Yamatocetus (right) - indicating antitropical distribution in both hemispheres - and a cf. Waharoa (left) from the earliest Miocene, indicating that eomysticetids survived into the Miocene epoch!

The deltoid is pretty far forwards, and so the placement of the AMNH whale's band-aid is possibly over the olecranon process and right over the elbow rather than deltoid. So, I would've shifted it slightly further forward [also from Schulte 1916]

Normally used to just move the humerus, in cetaceans, the shoulder muscles are MASSIVE and the scapula is enormous - all because they've been co-opted to move the entire, stiffened flipper skeleton. [fetal Sei whale flipper, Schulte, 1916]
