Palaeontologists have identified a new species of dinosaur in northern Mexico after its remnants were identified almost 10 years ago.
The specimen dates back 73 million years called Tlatolophusgalorum, was a crested dinosaur. It’s crest's shape is similar to a "symbol used by Mesoamerican people in ancient manuscripts to represent the action of communication and knowledge itself."
The investigation began in 2013, included specialists from the National Institute of Anthropology and History (INAH) and National Autonomous University of Mexico (UNAM). A tail of the dinosaur was first discovered in the state of Coahuila.
Research about the new dinosaur species was published in Cretaceous Research, a scientific journal. The INAH said this discovery was an "exceptional case" in Mexican palaeontology.
Scientists said that the dinosaur was an herbivorous animal, and the conditions in which it was found explained its preservation. It stated “About 72 or 73 million years ago, a huge herbivore dinosaur died in what must have been a body of water full of sediment, so that its body was quickly covered by the earth and could be preserved through the ages."
Tlatolophus is derived from a term in the Indigenous Mexican language of Nahuatl and the Greek term meaning "chest." Galorum is a reference to the scientists involved in the research.
Scientists said that the dinosaur had ears that could hear low-frequency sounds. Palaeontologists also believe that this dinosaur "emitted strong sounds to scare away predators or for reproductive purposes."
