In a remarkable discovery, a team of archaeologists has unearthed the fossilized remains of a 72 million-year-old dinosaur tail in a desert in northern Mexico. This find is an unprecedented and significant breakthrough in the field of paleontology, shedding new light on the ancient history of this region.

The exceptionally well-preserved tail is the first of its kind to be found in Mexico and is a testament to the dedication and expertise of the researchers involved. Francisco Aguilar, the director of the country’s National Institute for Anthropology and History (INAH), described the find as a unique and invaluable discovery.
The team of archaeologists and students from INAH and the National Autonomous University of Mexico identified the fossil as belonging to a hadrosaur, a duck-billed dinosaur species.
What makes this discovery even more exciting is that the tail, measuring approximately 50 centimeters in length, is remarkably well-preserved, retaining its structure after spending over 20 days in the desert’s scorching heat.
Preservation of this degree is rare and offers a wealth of information to scientists eager to study the ancient past. The team found the tail in a region known as General Cepeda, located in the northern state of Coahuila, which was once part of the ancient desert landscape.
The tail’s excellent preservation means that it can potentially provide insights into the dinosaur’s behavior, environment, and the conditions it faced. The researchers are particularly excited about studying the tail for signs of trauma or injury, which may offer clues about the life of this remarkable creature.
Mexico, with its rich paleontological heritage, has been home to various dinosaur discoveries, but this find stands out as the first dinosaur tail of its kind. It’s believed to be approximately 72 million years old, dating back to the late Cretaceous period, when much of what is now central Mexico was underwater.
The ancient landscape of the region has preserved numerous fossils, allowing scientists to piece together the history of life on Earth during the Cretaceous period. It’s worth noting that most dinosaur remains, with the exception of hadrosaurs and ceratopsians, have been found in marine deposits.
The story of this tail’s discovery began in June 2012 when it was first spotted by local residents. After initial inspections, a team from INAH embarked on the delicate excavation of the tail this month. The fossilized tail will be carefully transported to General Cepeda for cleaning and further investigation.
The find is an exciting development in the field of paleontology, as it has the potential to answer many questions about the dinosaurs that once roamed the ancient Mexican landscape.
It serves as a reminder that our planet holds many secrets in its geological layers, and dedicated researchers continue to unearth and study the remnants of these incredible creatures, piece by piece.
