Antarctopelta is a genus of extinct herbivorous ankylosaurid dinosaur from the Early Cretaceous period of Antarctica. It is the oldest known ankylosaurid found in Antarctica and the only known ankylosaurid from the Southern Hemisphere. Antarctopelta was about 3 meters (10 feet) long and weighed about 500 kg (1100 lbs). Its body was heavily armored with spikes, plates, and scutes. Its main defense was its club-like tail, which it could swing to ward off predators. Its head was small, with a short snout and large, bony eye sockets. It had a small crest running down the back of its head. Its diet consisted mainly of low-growing plants, such as ferns, cycads, and conifers.

Antarctopelta dinosaurs are a type of armored dinosaur that lived in Antarctica during the Late Cretaceous period, approximately 70 million years ago.
These dinosaurs were first discovered in 1986 by paleontologists from the Antarctic Peninsula. They were identified from a single fossil specimen found in the La Meseta Formation of Seymour Island.
Antarctopelta were quadrupeds with a short, wide body and short limbs. They had an armor-like covering of scutes made of bone and keratin.
These scutes provided protection and insulation against the harsh Antarctic climate. The head was large and had a blunt snout, with large eyes and a wide mouth.
The Antarctopelta was an herbivore that lived in warm, shallow waters. It is believed that it fed on aquatic plants, algae, and small invertebrates.
It was a slow-moving animal and may have used its armor-like scutes to deter predators.
Antarctopelta is classified as a nodosaurid, which is a group of ankylosaurian dinosaurs that lived during the Cretaceous period.
They are closely related to the Ankylosaurus and Edmontonia, which lived in North America during the same period.
The Antarctopelta remains the only known dinosaur species known to have lived in Antarctica. It is believed to have gone extinct due to the changing climate and the onset of the ice age.
Its fossils provide valuable insight into the evolution of ankylosaurians and the ecology of Antarctic ecosystems during the Cretaceous period.
Antarctopelta dinosaurs were large, herbivorous, quadrupedal dinosaurs that lived during the Late Cretaceous period. They were most likely relatively social animals, living and traveling in groups.
Antarctopelta dinosaurs had a variety of behaviors and social interactions. For example, they likely engaged in mutual grooming, helping to keep each other clean and free from parasites. They may have also engaged in courtship displays and mating rituals. They may have also competed for resources, such as food and water, and defended territories.
Antarctopelta dinosaurs also had an array of social communication behaviors. They likely communicated with one another through visual and vocal signals, such as facial expressions, body language, and vocalizations. These behaviors could have been used to express emotions and convey information.
Antarctopelta dinosaurs likely had complex social structures. They likely formed social hierarchies, with some individuals having higher social status than others. This could have been based on age, size, or possibly even dominance behaviors.
Antarctopelta dinosaurs likely had complex social behaviors and interactions. These behaviors could have helped them to survive, reproduce, and thrive in their environment.
In 2017, a study by paleontologists published in the journal PLOS One described the discovery of a new species of ankylosaurian dinosaur – Antarctopelta oliveroi – from the Late Cretaceous period in Antarctica. The fossil was recovered from the Marambio Group in the Central Transantarctic Mountains and dates to between 77.5 and 69.9 million years ago.
The fossil is well-preserved, including fragments of the skull, neck, and body armor. It is among the most complete ankylosaur specimens ever found in Antarctica. The fossil suggests that Antarctopelta was a medium-sized ankylosaur, measuring approximately 5.5 meters (18 feet) in length.
Analysis of the fossil indicates that Antarctopelta had several unique features that distinguish it from other ankylosaurids, including a unique pattern of ossification in its body armor, a unique arrangement of its armor plates, and several other unique skull features.
The research team suggests that Antarctopelta was most likely well-adapted to the cold Antarctic climate and was likely an herbivore that fed on plants growing in the region. The discovery of this new species provides an important insight into the diversity of Antarctic dinosaurs during the Late Cretaceous period.
