Gaia.com continues to release videos and insist a genuine investigation is underway, despite scientists rounding on the online paranormal website amid claims it is pushing a massive elaborate hoax.
The team claims to have found three eggs inside an alleged alien mummy.
However, the outlandish claims continue to be made by the Gaia.com team.
In the latest video Dr Edson Salazar Vivanco, who has been involved in previous examinations of body parts that have been suggested could be alien in origin, said of one of the creatures: “The physical examination revealed that in the pelvic cavity there was a bump. This may have been its last meal, it may be something else, or it maybe gestation.”
The team said a frontal and lateral X-ray has been carried out on it.
José de la Cruz Rios, is described as a biologist in the film.
He previously worked with Mr Maussan on claims that an old slide found near Roswell, New Mexico, USA, showed the body of an alien recovered from the infamous alleged flying saucer crash of 1947.
This was later found to be the remains of a mummified human child.
Mr de la Cruz Rios says in the video: “In the pelvic cavity we see the presence of eggs.
“They are translucent meaning they consist of an organic substance.”
The team concluded the “creatures” reproduced by laying eggs in a similar manner to reptiles on Earth, but were humanoid in appearance.
In the footage, a video narrator said: “Coming up. The team examines a new body recovered from the tomb.
“It appears to be a baby, and they have named this one Wawita, which means baby in the Cashua language.”
Many ufologists believe the Gaia.com films are promoting a massive hoax.
Nigel Watson, author of the UFO Investigations Manual said they were “plaster of Paris fakes”.
Express.co.uk has asked Gaia.com and Mr Maussan for details about where the so-called alien mummies were discovered.
Both Gaia.com and Mr Maussan failed to answer.
However, footage in the new video shows what appears to be the entrance to the tomb and mummified remains buried in there, at an undisclosed location.
Mr Maussan said at an earlier press conference about the discovery that the mummified burial of the bodies suggests they once coexisted with humans.
He said: “These mummies were buried in human tombs, in sacred places.
Gaia.com claim tests show the bones to be 1,700 years old, and the beings had three fingers and elongated skulls.
For years there have been claims by alien conspiracy theorists that aliens visited our ancestors and helped them build great structures like the Pyramids of Giza and Stonehenge.
UK-based UFO investigators Steve Mera and Barry Fitzgerald have set out to get to to the truth.
In a press release, the pair said: “Recently, the internet exploded with images of newly discovered mummies, discovered in the region of Nazca, Peru.
“This is not the first time such earth shaking discoveries have been found, only to turn out to have a more mundane explanation.
“Could these recent findings be what we have been waiting for?
“We have recently returned from Peru after conducting a painstaking and thorough investigation that encompasses physical examinations of the bodies, scrutinising X-rays and scans, reviewing medical conclusions and being cast into the murky depths of the illegal black market.”
Mr Mera told Express.co.uk: “We are at this time in discussions with doctors at universities around the UK.”
