Acristavus Dinosaur is a genus of small-bodied, herbivorous dinosaurs from the Late Triassic period. It was first described in 2019, and its remains have been found in the southwestern United States. Acristavus is known from a single species, A. gagslarsoni, which is the only known species in the genus.

Acristavus was a small, bipedal dinosaur. Its skull was only around 5 cm in length, and its body was estimated to be around 1.5 meters in length. The fossil remains suggest that Acristavus was a herbivore, and its diet likely consisted of low-lying plants and shrubs.
Acristavus is significant in that it is one of the first dinosaurs to be discovered in the Late Triassic period, about 230 million years ago. This is an important discovery, as it suggests that the earliest dinosaurs may have evolved during the Triassic period, rather than during the Jurassic period as was previously thought.
The discovery ofalso sheds light on the early evolution of dinosaurs. Its small body size, bipedal stance, and herbivorous diet suggest that Acristavus may have been an early member of the Ornithischia group, which includes the iconic "duck-billed" dinosaurs.
Acristavus Facts
| Name: | Acristavus Dinosaurs |
| Size: | Around 5 cm in length, and its body was estimated to be around 1.5 meters in length. |
| Main Facts: | Acristavus dinosaurs is that they were small, bipedal dinosauriformes that lived during the Late Triassic period (around 210 to 205 million years ago). They were some of the earliest known dinosauriformes, and are thought to be closely related to the ancestors of true dinosaurs. |
Acristavus is a genus of small, bird-like dinosaurs that lived during the late Cretaceous period in what is now North America. The genus includes two species, Acristavus gagslarsoni and Acristavus gracilis.
Acristavus is believed to have been a small, lightly-built, and possibly omnivorous dinosaur. They would have been approximately 1 meter in length and weighed up to 15 kilograms. Acristavus had long, slender legs and a long tail that was likely used for balance when running. Its skull was short and wide, with a short snout and a large braincase.
Acristavus is considered to be one of the earliest members of the Ornithomimosauria, a group of theropod dinosaurs that may have been closely related to birds. Acristavus is thought to have been an early ancestor of modern birds, and its skeletal structure is similar to that of modern birds.
Acristavus is known only from a few fragmentary fossils, so its exact behavior and ecology remain unknown. It is possible that Acristavus lived in herds and foraged for plants, insects, and small animals. Acristavus may have been a fast runner, capable of avoiding predators and chasing down prey.
Acristavus is an extinct genus of small, primitive, toothed birds that lived during the early Eocene (about 55 million years ago). They had a long, slender beak, a small head, and a long tail. Acristavus were small, probably about the size of a sparrow, and had a single claw on the leading edge of each wing that may have been used for climbing. They were probably omnivorous, eating a variety of insects, small vertebrates, and fruits. Acristavus is one of the earliest known birds, and its fossils are found in Europe and North America.
