On Stuff You Should Know, Josh Clark and Chuck Bryant explore trovants, unusual rock formations found in Romania's Carpathian region that appear to grow and multiply. These geological formations, which range from tiny pebbles to massive 15-foot structures, secrete cement-like substances and expand when exposed to rainwater, creating what looks like "offspring" through chemical reactions and internal pressure.
The hosts explain how these formations differ from typical mineral concretions and discuss their likely marine origins, supported by the presence of ancient marine fossils and calcium carbonate. The episode covers the scientific investigation of trovants, their protection under UNESCO at the Trovants Museum Natural Reserve, and the various theories about their formation during the middle Miocene epoch.

In the Carpathian region of Romania, a fascinating geological phenomenon known as trovants has captured attention. These unique rock formations exhibit extraordinary characteristics, most notably their ability to appear to grow and multiply. According to Chuck Bryant, trovants secrete cement-like substances that solidify after exposure to water, creating what looks like offspring. Josh Clark adds that these formations tend to take on spherical shapes as they develop. These remarkable stones range dramatically in size, from tiny pebbles less than an inch across to massive structures reaching over 15 feet high and weighing several tons.
While initially hypothesized to be mineral concretions, scientists discovered that trovants lack the characteristic nucleus found in concretions. The International Geological Congress in Oslo proposed that these formations resulted from minerals, primarily calcium carbonate, delivered by a prehistoric river and compressed during the middle Miocene epoch. Clark explains that trovants grow through chemical reactions creating internal pressure, causing them to expand over time. Their porous calcium carbonate sandstone structure allows them to absorb and secrete minerals when exposed to rainwater, leading to their unique growth patterns.
The scientific community has long been intrigued by trovants, with some researchers even claiming to have observed them moving. These formations often contain marine fossils, such as bivalves and gastropods, suggesting they originated in an ancient marine environment. The presence of calcium carbonate, a primary component of marine shells, further supports this theory.
Trovants are predominantly found in Romania's Valcea County, particularly in the villages of Otasani and Costesti. The Trovants Museum Natural Reserve serves as a protective sanctuary for these formations. Due to their scientific and educational significance, trovants are protected under UNESCO, which prohibits any actions that might damage or remove them from their natural environment.
1-Page Summary
In Carpathian Romania, a mysterious and unique geological phenomenon catches the eye of locals and visitors alike. These are the trovants, rock formations that are far from ordinary.
The trovants possess a distinctive appearance that compels onlookers to take a second look. Notably, these rocks seem to be capable of growth, as smaller rocks emerge from the larger formations. This peculiar characteristic imparts a bizarre, almost alien-like quality to these geological formations.
Chuck Bryant highlights the unique nature of trovants, noting their ability to secrete cement-like substances that solidify to form what appears to be offspring after being exposed to water, such as during a rain. This curious behavior often leads people to anthropomorphize the trovants, imagining them to be living entities of some sort.
Additionally, Josh Clark clarifies their tendency to take on spherical shapes as they "grow," further adding to their mystical allure.
The trovants come in various sizes, ranging from the minuscule to the monumental. On the smaller end of the spectrum, they can measure less than an inch acro ...
Description of Trovants
Scientists have proposed different theories to explain the intriguing phenomena of trovants, unusual rock formations that seem to grow and multiply over time.
Initially, when scientists delved into the study of trovants, there was a hypothesis that these rocks were a form of concretion. This theory suggested that trovants start out small and accumulate layers of sandstone and other minerals which allow them to grow larger.
It was long thought that trovants were concretions, but upon closer inspection, it was found that trovants did not have a nucleus, which is a typical characteristic of concretions. Unlike concretions, which are usually composed of various sediments, trovants are made exclusively of sandstone, specifically calcium carbonate sandstone.
The International Geological Congress in Oslo put forth a hypothesis that trovants were formed through the actions of minerals delivered by a prehistoric river in a slurry solution, predominantly made of calcium carbonate. They agreed that compression—as from an earthquake during the middle Miocene epoch—played a role in compacting the sandstone.
Further understanding of trovants emerged with the realization that their growth was facilitated by their peculiar nature. Th ...
Theories on the Formation and Growth of Trovants
Clark and Bryant delve into the enigmatic world of trovants—rock-like forms that have sparked scientific curiosity and public fascination, with attention given to their growth and seemingly unconventional behaviors.
There is an intrinsic fascination with trovants, often compared to living entities or even alien pods, owing to their unique ability to grow and secrete, behaviors that seem almost extraterrestrial. Some researchers have gone as far as claiming to have observed trovants moving—an assertion that adds to the mystery of these geological formations. The International Geological Congress, held in Oslo in 2008, attempted to demystify trovants, moving beyond the notion that they were merely concretions and working towards providing a new scientific explanation for their existence.
It's notable that these trovants often contain ...
Historical Perspectives and Scientific Investigation of Trovants
Trovants, the unique geological formations found predominantly in Romania, draw attention due to their intriguing nature and are safeguarded by international efforts.
In Romania, trovants are most notably found in areas with significant concentrations such as the Trovants Museum Natural Reserve in Valcea County. Additionally, the villages of Otasani and Costesti are recognized for their presence of these geological formations.
The Trovants Museum Natural Reserve offers protection to these distinctive stones, ensuring they remain undisturbed in their natural environment. This safeguarding preserves their structure and scientific value.
Trovants are not just a local curiosity but are ...
