At public hearing in the Mexican Chamber of Deputies, infamous TV ufologist Jamie Maussan presented two small mummified "alien bodies"
The hearing was orgianized by deputy Sergio Gutiérrez Luna.
In Mexico, the public hearing is organized by the Morenoist deputy Sergio Gutiérrez Luna and the communicator Jaime Maussan. According to the latter, the hearing seeks to establish a criterion to define unidentified aerial phenomena, and include it in the Airspace Protection Law.
Also speaking were Ryan Graves and Robert Sallas.
Here's the unboxing of the aliens.
Maussan has a poor reputation, even amongst UFO fans, he's been parading these and similar bodies around for year. They are generally considered to be fakes, made, in part, from human remains. It came up before on Metabunk in 2017:
Similarly one might create a long three-fingered hand by removing the outer two digits and then splitting the flesh down between the metacarpals which are normally inside the hand.
Once you've gone down that road, you could easily extend it by adding additional bone segments, like in this earlier example from the same people with a structurally implausible number of bones:
And there's some academic debunking
Recent on-line and television appearance of purportedly extraterrestrial remains excavated in unknown circumstances in the Southern Peruvian coast has revealed itself as the end product of a long process which joins grave looting, yellow press, and some disoriented professionals. Organizers and attendees to the IX World Congress on Mummy Studies held in Lima, Peru, faced a disinformation campaign by presenting a declaration preventing the public and the media of this hoax. Since then, the producers of this scam program have kept, unfortunately, trying to validate their claims by using fallacious strategies, fueled by the revenue of selling the show.

There's a lot more investigation/debunking, as I recall, and we should try to gather it here, as the hearings are getting a lot of unwarranted attention
