When you think of predators, you probably imagine big animals with sharp paws or teeth like tigers or sharks. For more than 100 million years, a small terrible predator is a predator with jaws like Skythe.
While investigating a large fossil insect in the Zoology Museum in São Paulo, Brazil researchers, 113 million-year-old fossils represented a new ant and the oldest antimenth sample, which could be an oldest ant. The transitional ant, vulner-made cratensis, is an extinct ant subfamili member Haidomirmecinae. Were available in haidomyrmecinae ants, called “Hell Ants”, respectively A period of concern (145 million to 66 million years ago) and are known for pale and highly specialized jaws.
“Our team, São Paulo University at the University of Ants, researcher Anderson Lepeco in the University of São Paulo, in a cell press statement. “This discovery is especially interesting, ‘hell ant’, known as the strange predator adaptations, refers to the not exposed.”
The author of Lepeco A learn The discovery was published in the current biology on Thursday. Colleagues and colleagues and colleagues, hell stored in lime, have learned through a 3D image technique called micro-calculated tomography that reveals the tasks of objects. According to the analysis, the ant, in front of the eyes in front of the head in front of the head in front of the head in parallel with the shape of the head. In contrast, the mandibles in modern ants are moving side by side.
“113 million years ago, finding such an anatomically special ant, it complicates our assumptions that these insects develop complex adaptations,” Lepeco said. “Ink morphology shows that even the earliest ants are developing significantly different ink predatory strategies from their modern counterparts.”
In addition, researchers have realized that the samples are closely related to other previously detected hell of other previously detected hell in Myanmar in Myanmar. Came since volcaniardris cratensis Crato formation– This is the hot point in the northeastern Brazil – this shows that 113 million years ago, haidomyrmecinae ants spread to each world.
“When confronting this extraordinary sample, we were not like a new kind of potentially, potentially the formation of Crato,” said Lepeco. “This finding emphasizes the importance of the comprehensive examination of the existing collections – in personal or museums – and the Paleontology of Brazil and the country has not been formed in the fossil insect fauna.”
The study shows that the ants show that the ants are already diversified and expanded in the world, which shines in the world 113 million years ago one of the most successful insects on the planet.
