**Tlatolophus: A Unique Dinosaur**
Tlatolophus is a type of dinosaur known as a hadrosaurid, which lived during the Late Cretaceous period, around 73 to 72.5 million years ago. This dinosaur was discovered in Mexico, specifically in the Cerro del Pueblo Formation.
**Discovery**
The first Tlatolophus fossil was found in 2005. It was a part of a tail. In 2013, scientists worked together to collect more of the dinosaur’s remains. This led to the finding of a nearly complete skeleton, which is one of the most complete known for this group in Mexico.
Tlatolophus was officially named in 2021. The name comes from the Náhuatl word “tlatolli,” meaning “word,” and the Greek word “lophos,” meaning “crest.” This is because the dinosaur’s crest looks like a glyph, or symbol, that resembles a word in ancient Aztec writing. The species name, Tlatolophus galorum, honors two families who helped with the discovery.
**Description**
Tlatolophus was a large dinosaur that measured about 8 meters long, or around 26 feet. It likely weighed nearly 3 metric tons, which is quite heavy! Its skull is tall and features a long crest that is shaped like a comma. It also has very distinct nasal areas, and many other parts of its skeleton, including a tail, have been preserved.
**Classification**
Tlatolophus is part of the Parasaurolophini tribe, which includes other dinosaurs with similar features. This classification was determined by researchers who studied its physical characteristics.
In summary, Tlatolophus is a fascinating dinosaur with a unique crest and an interesting background. Its discovery helps scientists understand more about dinosaur life during its time in ancient Mexico.
