The bones in the Midnight Terror Cave were carefully examined and found inexplicable footprints.

More than 15 years after scientists discovered the Midnight Terror Cave in Belize, it is still

continue to explore. Namely, the remains of 100 people who were sacrificed to the Mayan rain god almost 1000 years ago.

The cave was used for burialduring the Classic Maya period (250-925 CE) and was named so by the locals. Professors and students have concluded that the more than 10,000 bones found in the cave belong to at least 118 people. Many showed signs of injuries inflicted on them shortly before their death.

Now to better explore the final points.the lives of the victims, scientists did not look at the bones, but studied the oral cavity, examining the calcified plaque on their teeth - tartar. Archaeologists and paleontologists have found curious blue fibers stuck to the teeth of at least two victims.

Tartar can retain microscopicpieces of food that someone has eaten, such as pollen grains, starches, and phytoliths, the mineralized parts of plants. Cotton fibers have been found on victims of Maya rituals. Some of them are bright blue. Scientists noted that this was a surprise. It is worth noting that the color blue is important in Maya rituals.

Some scientists have suggested that fibersleft over from the gags given to the victims. However, other researchers were skeptical about the idea. Perhaps in the future, experts will conduct a more detailed analysis. Prior to this study, blue fibers had been found in agave-based alcoholic beverages from burials in Teotihuacan.
