Which animal is this skull from?

I was told it was found some decades ago in a river bed in Buenos Aires, Argentina.

I tried image searching it but couldn't quite find an equal one.

Also looks wrong for the location. Does anyone know which animal could it have been?

Looks a bit like a seal skull to me.

Edit: maybe a South American sea lion

Yes I think you might be right, it does look a lot like a sea lion. Especially because of the two sets of fangs. Thank you.

I'm just some guy, but I agree that it looks like a South American sea lion skull. Missing the lower jaw and some upper teeth, and possibly with a damaged sinus cavity

One of the tests they have for Palaeontology students is give them a Sea-lion skull, grey wolf skull, red fox skull and cast of a Thylacine skull.

Most of the time, they can differentiate the sea-lion or the Wolf, (both Canids), but cant differentiate the Fox from the Tassie Tiger.

Is this just a fun anecdote or are you telling me something about my guess? Because I just woke up and don't know how to take things yet

Just an anecdote. I agree with you that it is probably some sort of pinniped (seal or sea-lion)

I think it's a fish.

To check, we count the number of bones in the skull. One in the bottom, one in the top, lots of teeth, but not enough to be a fish.
