Ziapelta is an extinct genus of ankylosaurid, which roamed the earth during the Upper Cretaceous period, around 74.8 to 72.8 million years ago. Its fossils were discovered in the Hunter Wash and De-na-zin members of the Kirtland Formation in New Mexico. The genus is named after the Zia sun symbol, a stylized sun with four rays that has been used for centuries by the Zia Pueblo people of New Mexico.
The newly discovered ankylosaurid, Ziapelta sanjuanensis, was named in 2014 after an extensive research paper led by ankylosaur researcher Victoria Arbour. This dinosaur had a prickly appearance, with large outwardly-curved horns on the back of its skull and cervical half rings covering its neck. Its fossilized skull and bones were uncovered from the Kirtland Formation at Hunter Wash, San Juan Basin, in northwestern New Mexico in 2011.
Ziapelta sanjuanensis is a single species in the genus, and it is the newest dinosaur to be discovered in New Mexico. The discovery of this dinosaur has provided scientists with more information on the evolution of ankylosaurids and the biodiversity during the late Cretaceous period.
Discovery of Ziapelta
Historical Background
Ziapelta is an extinct genus of ankylosaurid that was named in 2014, in a research paper led by ankylosaur researcher Victoria Arbour. The genus is named after the Zia sun symbol, a stylized sun with four rays that is depicted on the flag of New Mexico. The discovery of Ziapelta is significant because it is one of the few ankylosaurid dinosaurs known from the Late Cretaceous of North America.
Location and Date
The fossils of Ziapelta were discovered in the Hunter Wash and De-na-zin members of the Kirtland Formation of Upper Cretaceous New Mexico in 2011. The discovery was made by a team from the New Mexico Museum of Natural History and Science and the University of Alberta. The location where the fossils were found is in the Bisti/De-na-zin Wilderness area of New Mexico. The fossils were found in rocks that are about 74.8 to 72.8 million years old, during the Kirtlandian land-vertebrate faunal age. The discovery of Ziapelta provides important information about the evolution of ankylosaurid dinosaurs in North America during the Late Cretaceous period.
Description of Ziapelta
Physical Characteristics
Ziapelta is an extinct genus of ankylosaurid dinosaurs that lived during the Late Cretaceous period. Based on the fossils discovered, it is estimated that Ziapelta was between 15 and 20 feet long, with a weight of around 2 tons. The herbivore had a bulky body supported by four stout legs, a short tail, and a broad skull. The back of its skull had large, outwardly-curved horns, which gave it a prickly appearance.
Armor and Defense
Ziapelta had a unique feature that distinguished it from other ankylosaurids: the cervical half rings that covered its neck were decorated with spines. These spines acted as a defense mechanism against predators. The dinosaur’s body was also covered in bony armor plates, which provided additional protection. The bony armor plates were fused to the underlying bones, making them an integral part of the skeleton. Overall, Ziapelta was a well-protected herbivore, making it difficult for predators to attack it successfully.
In summary, Ziapelta was a bulky, well-armored dinosaur that lived during the Late Cretaceous period. Its unique physical characteristics, such as the spines on its cervical half rings and the bony armor plates covering its body, made it a formidable opponent for predators.
Classification
Taxonomy
Ziapelta is an extinct genus of ankylosaurid, which belongs to the family Ankylosauridae, a group of herbivorous dinosaurs that lived during the Late Cretaceous period. The genus was named after the Zia sun symbol, a stylized sun with four rays emanating from a central circle, which is the symbol of the state of New Mexico. There is only one species in the genus, Ziapelta sanjuanensis.
The first fossils of Ziapelta were discovered in the Hunter Wash and De-na-zin members of the Kirtland Formation of Upper Cretaceous New Mexico. The fossils were described in 2014, in a research paper led by ankylosaur researcher Victoria Arbour.
Evolutionary Significance
Ziapelta is an important dinosaur for understanding the evolution of ankylosaurids. It is one of the most basal members of the family, which means that it is one of the earliest known ankylosaurids. Its fossils provide valuable information about the early evolution of the group, including the development of the characteristic armor and weaponized tail that are typical of ankylosaurids.
Ziapelta also shows some unique features that distinguish it from other ankylosaurids. For example, its skull has large, outwardly-curved horns on the back, which are not found in other ankylosaurids. Its cervical half rings, which cover the dinosaur’s neck, are also decorated with unique features. These unique features make Ziapelta an important dinosaur for understanding the diversity and evolution of ankylosaurids during the Late Cretaceous period.
Paleobiology
Diet and Feeding Habits
Ziapelta was an herbivorous dinosaur that relied on plants for its sustenance. Its teeth were shaped like broad, serrated blades, which were ideal for ripping and tearing through tough vegetation. It is believed that Ziapelta had a diet similar to other ankylosaurids, which consisted of low-lying ferns, cycads, and conifers. Its powerful jaws and muscular neck would have allowed it to chew through even the toughest plant material.
Habitat and Ecology
Ziapelta lived during the Late Cretaceous period, approximately 74.8 to 72.8 million years ago. It was found in the Hunter Wash and De-na-zin members of the Kirtland Formation of Upper Cretaceous (Campanian) New Mexico. Ziapelta was a heavily armored dinosaur with a bony club at the end of its tail, which it likely used as a defensive weapon against predators. It was a relatively small ankylosaurid, measuring around 4 meters in length and weighing approximately 1,000 kg.
Ziapelta was well-adapted to its environment, with its armor providing protection against predators and its broad, flat teeth allowing it to efficiently process tough plant material. It likely lived in herds, as is common with other ankylosaurids, and may have migrated seasonally to find suitable food sources. Overall, Ziapelta was a fascinating dinosaur that played an important role in the Late Cretaceous ecosystem of western North America.
Fossil Record
Fossil Finds
Ziapelta is a genus of ankylosaurid dinosaur that lived during the Late Cretaceous period, about 74 million years ago. The first fossil of Ziapelta was discovered in 2011 by a team led by Robert Sullivan in the De-na-zin Member of the Kirtland Formation in New Mexico. The fossils included a complete skull and partial osteoderms. Another specimen was found in the Hunter Wash Member of the Kirtland Formation.
Preservation and Research
The fossils of Ziapelta were well-preserved and provided valuable information about the anatomy and evolution of ankylosaurids. The skull of Ziapelta was unique in that it had a triangular shape and a prominent nasal horn. The osteoderms were also distinctive, with a combination of small, round, and triangular shapes.
The fossils of Ziapelta were studied extensively by paleontologists, who used various techniques to reconstruct the appearance and behavior of this dinosaur. They found that Ziapelta was a herbivorous dinosaur that had a heavily armored body and a club-like tail that it used for defense against predators.
In conclusion, the fossil record of Ziapelta provides important insights into the evolution and diversity of ankylosaurids during the Late Cretaceous period. The well-preserved fossils of Ziapelta have helped scientists to better understand the anatomy and behavior of this dinosaur, and to reconstruct its appearance and lifestyle.
