Whale skulls don't have them.

Are you talking about the tiny pits above the premolars? Or the. Large holes on the lower jaw, those are nerve openings.
I never said modern whales have them.

The tiny pits.

I know, someone asked if whales had pits.

Ok.
They said embryonic whales had whiskers.

I ment whale skulls.  :-[
I know.

Ok
I may not like feathered dinosaurs and stumpy legged Spinosaurs, but I will keep those opinions to myself, I will not start a debate over it, I promise. 😇

Pits are more indicative of functioning whiskers, whereas embryonic whiskers seem vestigial in cetacea

Yes. So if modern cetaceans have embryonic whiskers than their ancestors must have had them at some point, right?

Okay, so my guess is Pakicetus probably had them, but what about Maiacetus?

I'm not sure, because it seems Maiacetus is more closely related to Rodhocetus and other more advanced proto-whales than to Ambulocetus, Pakicetus and their relatives.

Perhaps, although they would have had quite different lifestyles.

If Maiacetus had whiskers, and the whiskers were like a manatee's, they would serve no further purpose.

True, I'm leaning towards not putting whiskers on Maiacetus, but putting them on Pakicetus, Ambulocetus, and Himalayacetus (if I can find a place to add it into the series).

Not new, it was named in 1998.

Also, what is the first prehistoric whale thought to have had a melon?
