Ankylosaurus[nb 1] is a genus of armored dinosaur. Its fossils have been found in geological formations dating to the very end of the Cretaceous Period, about 68–66 million years ago, in western North America, making it among the last of the non-avian dinosaurs. It was named by Barnum Brown in 1908; the only species in the genus is A. magniventris. The genus name means "fused lizard", and the specific name means "great belly". A handful of specimens have been excavated to date, but a complete skeleton has not been discovered. Though other members of Ankylosauria are represented by more extensive fossil material, Ankylosaurus is often considered the archetypal member of its group, despite having some unusual features.
Possibly the largest-known ankylosaurid, Ankylosaurus is estimated to have been between 6 and 8 meters (20 and 26 ft) long and to have weighed between 4.8 and 8 metric tons (5.3 and 8.8 short tons). It was quadrupedal, with a broad, robust body. It had a wide, low skull, with two horns pointing backward from the back of the head, and two horns below these that pointed backward and down. Unlike other ankylosaurs, its nostrils faced sideways rather than towards the front. The front part of the jaws was covered in a beak, with rows of small, leaf-shaped teeth farther behind it. It was covered in armor plates, or osteoderms, with bony half-rings covering the neck, and had a large club on the end of its tail. Bones in the skull and other parts of the body were fused, increasing their strength, and this feature is the source of the genus name.
Ankylosaurus is a member of the family Ankylosauridae, and its closest relatives appear to be Anodontosaurus and Euoplocephalus. Ankylosaurus is thought to have been a slow-moving animal, able to make quick movements when necessary. Its broad muzzle indicates it was a non-selective browser. Sinuses and nasal chambers in the snout may have been for heat and water balance or may have played a role in vocalization. The tail club is thought to have been used in defense against predators or in intraspecific combat. Ankylosaurus has been found in the Hell Creek, Lance, Scollard, Frenchman, and Ferris formations, but appears to have been rare in its environment. Although it lived alongside a nodosaurid ankylosaur, their ranges and ecological niches do not appear to have overlapped, and Ankylosaurus may have inhabited upland areas. Ankylosaurus also lived alongside dinosaurs such as Tyrannosaurus, Triceratops, and Edmontosaurus.

Atrociraptor marshalli
Tumblr media
By José Carlos Cortés 
Etymology: Savage Thief
First Described By: Currie & Varricchio, 2004

Status: Extinct
Time and Place: About 68.5 million years ago, in the Maastrichtian age of the Late Cretaceous 
Tumblr media
Tumblr media
Atrociraptor is known from Unit 4 of the Horseshoe Canyon Formation, in Alberta, Canada 
Tumblr media
Physical Description: Atrociraptor was a fairly standard Dromaeosaur - a medium sized theropod, unfortunately there’s not much to be said about its body shape because only parts of the head have been preserved. That being said, it seemed to have a weirdly short and tall skull compared to other raptors. It had straight, but angled, teeth that formed a sort of rake structure within the mouth, with extremely large serrations. This probably would have had a major effect on how it grabbed prey. It probably was roughly the same size as Velociraptor, reaching about two meters long and around one meter tall, though it was potentially closely related to either Saurornitholestes or Deinonychus, and as such may have resembled them more than other dromaeosaurs.
Diet: As a Dromaeosaur, Atrociraptor would have primarily fed upon meat, especially as a predatory animal. As a medium to small sized predatory dinosaur, it would have stuck to smaller animals such as lizards and mammals, and only ventured to eat larger sources of food when the opportunity was good (such as when mob hunting or when the prey was sick or wounded. 
Tumblr media
By Calum O’Halloran 
Behavior: Like other raptors, Atrociraptor would probably have been mainly a solitary predator, stalking its prey and using ambush to attack - rather than pursuit. Though, of course, without preserved legs this is mainly a hypothesis based on its relatives. It would have used kicking and jumping to catch its prey by surprise, and used two specialized behaviors to hunt its prey: raptor prey restraint, where it flapped its wings very fast in order to stay balanced on top of struggling prey; and wing-assisted incline running, in which it flapped its wings hard to run up steep surfaces such as cliffs and trees - in order to chase food. If it lived in groups, it would have probably just been small families; and Atrociraptor probably took care of its young. 
Ecosystem: Atrociraptor is from the Horseshoe Canyon Formation, a late Cretaceous environment from Alberta, Canada. It was a fairly warm, arid environment, with consistently shifting terrain and features. Somewhat removed from the inland sea, it wasn’t associated with the coast like other late Cretaceous ecosystems (such as Hell Creek), and thus featured major differences in flora and fauna compared to these landscapes (for example, there was a surprising lack of turtles). As such, it was marked by small wet seasons, followed with very long dry seasons. All the water would drain from the land during these times, creating a vast scrubland. This was an environment dominated by ferns and more arid-adapted horsetails, though some conifers were present, along with flowering plants.

Many types of dinosaurs lived with Atrociraptor, including the ankylosaur Anodontosaurus, the small bipedal herbivore Parksosaurus, the hadrosaurs Hypacrosaurus and Saurolophus, a Leptoceratopsid of some sort, the tyrannosaurs Daspletosaurus and especially Albertosaurus, the ostrich mimic Struthiomimus, and the alvarezsaur Albertonykus. Weirdly enough, there were no large Ceratopsians in this environment, reflecting a gap in Ceratopsian evolution between the extreme diversity in the Campanian and the drop at the end of the Maastrichtian. There were also other reptiles, such as the Choristodere Champsosaurus.
Other: Atrociraptor has been heavily associated with Albertosaurus, though what that relationship might have been (if any) is uncertain.
