In the small town of Costesti, in Romania, the Trovanti Museum is located: a nature reserve that houses some mysterious rocks called Trovants. Their name means stones that grow because that is precisely what they do.

The phenomenon has caught the attention of scientists because they are apparently normal rocks. In fact, according to studies, Trovants have existed for over six million years. Initially they were pebbles, that is, small stones like those found in rivers.

But over the years their size has increased substantially and now they measure up to 10 meters and weigh around 320 kilos. Its growth, however, is extremely slow. They can take a thousand years to grow to just four or five centimeters.

According to experts, they are formed by a core of hard stone and sand, which works as a kind of shell. To analyze its interior, the scientists cut some stones and found that in addition to the sedimented sand they have mineral salts such as carbonates. Also, They could see that the Trovants have rings, like those that form the trunk of a tree, that is, in layers. This allowed them to even calculate the age of some of the rocks.
The researchers attributed its growth to rain. As they explain, when it rains the water presses the layers of sand and carbonates that make up the rockThis presses the lower layers of the sediments and thus, over the years, new reliefs begin to emerge.

Some are round, others oval, and even cylindrical, with a smooth surface. Many even claim that the rocks move up to 2.5 millimeters per week, but experts claim that this is due to the increase in mass on a specific side of the rock which produces a certain inclination.
The researchers concluded that they are inorganic life forms.
