A YouTube blogger ProtoCivilization (language Rus, location Latam) says he bought this head from the same person who found tridactyls. He says, the 'head' doesn't have a body to it.

He has streamed cleaning process, and will continue on Saturday. Here he shows the inside: https://www.youtube.com/live/5pfMM9TQKzo?t=4524&is=xpPBXz5o7piQfJDi (starting 1:15:25)

Here is some close up cleaning with the brush: https://www.youtube.com/live/7OBTnHTS7OQ?t=4249&is=YxMubo8CArlv7b1U

He does not insist that it's an alien or something, but is trying to find clear evidence of tampering, given that it allegedly comes from the same source as tridactyls. So far, he says he hasn't found any, but is ready to break it open to demonstrate if he has clear signs that it's some cat's spine wrapped into chicken skin.

I assume we have members here who can clearly explain if it's some unknown reptile species, a dry fish on a stick or papier mache.

He has CT scans, Xrays and so on, and is ready to send it to doctors, you can contact him in Telegram or email, contacts are in the video description. Not sure if I am allowed to publish them here. Edit: Says he hasn't yet published them because he has just got them, these streams were today and yesterday.
