The largest collective pit of the planet
Scientists have just excavated it
Scientists have unearthed the world's oldest "public toilet" about 240 million years old in Argentina.
Scientists say they have found thousands of fossil samples that Dinodontosaur dinosaurs - modern rhino herbivores - leave. This will be a clue to learning about diet, disease of prehistoric organisms and vegetation here.
Fossil dinosaur feces found in ancient latrines
In the excavation area, there are about 94 round pits, each area is about 10m². This fertilizer comes from the middle of Ky Tri Tri (Tam Diep), about 240 million years ago. The size and shape of the stool is quite diverse, with a diameter of 1- 35cm. The fossil is gray-brown, does not contain animal bones, only components from woody plants, seeds and pollen.
Dinodontosaur dinosaur
The discovery this time broke the record of "the oldest toilet" - 220 million years known earlier.
Elephants, antelopes and horses are modern animals that have a habit of toileting the whole herd into the same place to mark the territory and avoid parasites. However, this is the first time scientists have discovered the "collective toilet" of a large herbivore, dating back hundreds of millions of years ago.
According to the researchers, this hygiene method allows dinosaurs, which normally live in herds, to avoid parasites and keep animals from coming near them.
Dr. Fiorelli said: "The first thing is to avoid parasites but this is also a warning for predators of the time: Look, we are a big herd so beware!" .
