Acrocanthosaurus
Acrocanthosaurus (/ˌækroʊˌkænθəˈsɔːrəs/ ak-ro-KAN-thə-SAWR-əs; meaning "high-spined lizard") is a genus of carcharodontosaurid dinosaur that existed in what is now North America during the Aptian and early Albian stages of the Early Cretaceous. Like most dinosaur genera, Acrocanthosaurus contains only a single species, A. atokensis. Its fossil remains are found mainly in the U.S. states of Oklahoma, Texas, and Wyoming, although teeth attributed to Acrocanthosaurus have been found as far east as Maryland, suggesting a continent wide range. Acrocanthosaurus was a bipedal predator. As the name suggests, it is best known for the high neural spines on many of its vertebrae, which most likely supported a ridge of muscle over the animal's neck, back, and hips. Acrocanthosaurus was one of the largest theropods, reaching 11.5 meters (38 ft) in length, and weighing up to 6.2 metric tons (6.8 short tons). Large theropod footprints discovered in Texas may have been made by Acrocanthosaurus, although there is no direct association with skeletal remains.
Saurophaganax
Saurophaganax ("lord of lizard-eaters") is a genus of large allosaurid dinosaur from the Morrison Formation of Late Jurassic (latest Kimmeridgian age, about 151 million years ago) Oklahoma, United States.[1] Some paleontologists consider it to be a junior synonym and species of Allosaurus (as A. maximus). Saurophaganax represents a very large Morrison allosaurid characterized by horizontal laminae at the bases of the dorsal neural spines above the transverse processes, and "meat-chopper" chevrons. The maximum size of S. maximus has been estimated at anywhere from 10.5 meters (34 ft) to 13 meters (43 ft) in length, and 3 metric tons (3.3 short tons) to 4.5 metric tons (5.0 short tons) in weight.[5] In 2020, it was estimated at 3.5-3.8 tons, with a minimum average weight of 2.6 tons and a maximum average weight of 4.7 tons.
