Bicentenaria is an extinct genus of herbivorous neornithischian dinosaur from the Late Jurassic Period, about 155 million years ago. It is one of the few dinosaurs to have been discovered in modern-day Venezuela. The only known species of Bicentenaria is Bicentenaria argentina, named for the country in which it was discovered. Bicentenaria was a relatively small dinosaur, estimated to have been between 3 and 5 meters in length. It was bipedal, with an elongated neck and tail. The skull was elongated and rectangular, with tall, rounded cheekbones. Its teeth were adapted for herbivory, and were heavily worn down from use. Its hind legs were longer than its forelimbs, which gave it a slightly hunched posture.
Bicentenaria is believed to have been an omnivore, meaning it likely ate both plants and animals. It is thought to have been a fast runner, and its long neck and tail may have been used to help it move quickly through dense vegetation. It is also possible that it was a scavenger, using its sharp teeth to tear apart carcasses.

The extinction of the Bicentenaria dinosaurs is a relatively recent event in Earth's history. It occurred about 66 million years ago, in the same time period as the Cretaceous-Paleogene (K-Pg) mass extinction event.
This event is believed to have been caused by an asteroid collision with Earth, which released a massive amount of energy and debris into the atmosphere. This caused a global catastrophe, resulting in the extinction of many species, including the Bicentenaria dinosaurs.
The Bicentenaria dinosaurs were large, two-legged, herbivorous sauropods that lived in the late Cretaceous period. They were among the last of the sauropod dinosaurs to exist before their extinction. They were believed to be closely related to the titanosaurs, a group of sauropod dinosaurs that survived the K-Pg mass extinction.
The exact cause of the Bicentenaria extinction is uncertain, but researchers believe it was likely due to the environmental changes caused by the asteroid collision.
The impact would have released a significant amount of dust and debris into the atmosphere, blocking out the sun and causing global cooling. This would have resulted in a decrease in food availability for the Bicentenaria dinosaurs, leading to their extinction.
The asteroid impact may have caused oceanic acidification, resulting in the death of many marine species and the disruption of the food web. This could have been a major factor in the extinction of the Bicentenaria dinosaurs.
The Bicentenaria extinction is considered to be one of the most significant mass extinctions in Earth's history, and its effects can still be seen today.
The extinction of the Bicentenaria dinosaurs paved the way for the emergence of new species, such as mammals, that would eventually dominate the planet.
Bicentenaria dinosaurs are a rare group of extinct dinosaurs that lived during the Middle Jurassic period, approximately 180 million years ago. They are characterized by their large size and wide range of body shapes. The most notable feature of these dinosaurs is that they have two sets of teeth, which is why they are called "bicentenaria." This feature allowed them to feed on a variety of food types, ranging from plant material to other animals. Bicentenaria dinosaurs are known from fossils found in the Lagerstätten deposits in Argentina. These fossils are often exceptionally well-preserved, which is why they are so important for understanding the diversity and evolution of these animals.
The most well-known species of bicentenaria dinosaurs were the camarasaurids, which include the massive Camarasaurus and Diplodocus. Other bicentenaria species include Apatosaurus, Barosaurus, and Brachiosaurus. These animals had a variety of adaptations that allowed them to survive in their environment. For example, some had wide, robust bodies that allowed them to move through dense vegetation and other obstacles, while others had long necks that helped them reach foliage at the tops of tall trees.
Bicentenaria dinosaurs were also highly social animals and lived in large herds. This may have helped them to protect themselves from predators, as well as to find food. In conclusion, bicentenaria dinosaurs are an important group of extinct animals that provide us with insights into the diversity and evolution of dinosaurs. Their unique anatomy and adaptations allowed them to thrive in their environment and their social nature gave them a better chance of survival.
The behaviors of bicentenaria dinosaurs are difficult to study in detail due to the limited evidence available from the fossil record.
However, some inferences can be made about their behavior based on the physical characteristics of their bones, their environment, and their interactions with other species.
Bicentenaria dinosaurs, like all other dinosaurs, were social creatures that lived in large herds.
They roamed the land in search of food, often coming into contact with other species in the process. They were highly territorial, with members of the same species often competing for resources and space.
Bicentenaria dinosaurs were likely to be active both during the day and at night, as evidenced by the large eyes of some species.
They had a wide range of diets, including plants, fish, insects, and small animals. They were likely to hunt in packs, with the larger species being the most aggressive hunters.
The bicentenaria dinosaurs were also likely to migrate over long distances, which would have helped them to find new sources of food and to avoid predators.
They were also likely to engage in courtship behaviors, such as displaying their feathers and flapping their wings to attract mates.
The bicentenaria dinosaurs were highly social and active creatures, with each species exhibiting its own unique behaviors.
Their behaviors would have been greatly impacted by their environment and interactions with other species.
