Tyrannosaurus rex, although there is no concrete proof that it hunted in packs.
The T rex.
The HadrosaurusThe hadrasaurus was a large bipedal ornithischian, having a horny duck-like bill and webbed feet
An ankylosaurus is a large, herbivorous dinosaur which lived in the Cretaceous period, noted for its heavy armour and club-like tail.
An Edmontosaurus' diet consisted mainly of plants. This dinosaur, which was a herbivore, lived during the Cretaceous period, this duck-billed dinosaur was about 43 feet in length and weighed about three tons.
Yes. They are described as being very fast runners and having large eyes for night time hunting. Their body type indicates they most likely were omnivores.
The Alamosaurus are part of the Titanosaurus family. It has a long neck and tail, also columnbular legs. It is approximately 69 ft long and 33 tons. It is a quadrupedal plant-eating dinosaur. It has flat and slender teeth meant for plants, not meat. The first findings was found in North America in states like New Mexico, Utah, and Texas. These huge dinosaurs was preyed on by tyrannosauruses and many more.
Theropods are an extinct group of bipedal, carnivorous dinosaurs.They varied in their size and diet. Some theropods such as Velociraptor were the size of turkeys; others, such as Tyrannosaurus, were many times taller than humans. Some ate small animals such as lizards and insects. Others feasted on the meat of large herbivorous dinosaurs.

Yes, Giganotosaurus was a huge carnivorous dinosaur that was slightly larger than T-Rex. Giganotosaurus lived in South America during the early cretaceous and probably hunted large herbivores like Argentinosaurus.
The common consensus is that dinosaurs dominated the land, being the most diverse large animals, and reaching huge sizes. In the oceans, large marine creatures included plesiosaurs, pliosaurs, ichthyosaurs (during the Jurassic and early Cretaceous), and mosasaurs (during the Cretaceous). The skies were ruled by pterosaurs. Coniferous trees were the primary large plants.
Reptiles were the primary large animals during the Cretaceous period. On land, there were dinosaurs, in the air were pterosaurs, and the oceans were inhabited by plesiosaurs and mosasaurs.
