Katarina

This utterly baffling skull was unveiled in 2026. There are reasonable doubts about its authenticity.

Katarina: the mouth, the nostrils, the metal implant

Katarina was discovered by Dr. Edson Salazar Vivenco.

Features

Length: 39 cm
Width: 15 cm
Height: 18 cm
Species: unknown
A metal implant on the head
and possibly an implant beneath the top layer
4 “spine”-shaped protrusions on the top of the rear section

Katarina's dentition: 8 teeth on the upper jaw, 4 on the lower jaw. There is also what appears to be a *Jacobson's organ in the roof of her mouth.

*In snakes and lizards, this organ—also known as the “vomero-nasal organ”—is used to detect chemicals, for example, by collecting particles with their tongues and then depositing them in the organ.

Katarina's right eye: you can see her eyelashes.

The “spines” on the top of the back of Katarina's skull. These are bony structures that contain soft tissue. They measure between 4 and 8 cm.

Observations

Christophe Serres, who developed the 3D Viewer, identified some interesting aspects based on Katarina's DICOM images.

Katarina's skull has a unique structure: it lacks the typical bony plates, but instead consists of “tubes” radiating from the eye sockets, with plates between these tubular structures.

Tubular bone structures
Plates between the tubular structures
Four “spines.” Hollow bone structures that contain soft tissue
Orbital structure, which is a key component of the skeletal structure

It is clear that the bone structure has left its mark on the muscles and soft tissues.

There appear to be two implants.

The first is visible through the diatom layer.
The second is deeply embedded in the epithelial layers, on the bony layer of the skull beneath the upper nostril.

Its shape and density suggest that it is an implant.
