Pack Hunting In Carnosaurs Fact Or Fiction?
by: Jonathan I., Grade: 6+


For years people thought that the giant Carnosaurs were solitary hunters but now new evidence is coming to light that shows that maybe large predators did sometimes hunt in packs. It all started when the giant sauropod Argentinosaurus (Supposedley the biggest dinosaur ever found) was discovered in Patigonia in 1994. A few years after in 1996 anovergiant discovey was made. Giganotosaurus 8 tons of meat eating 'machine' 14.5 metres long.This was the only animal found in south america big enough to kill argentinosaurus but it would still have to hunt in packs to bring one down. But there was a big problem. At the time it was thought that all of the large predatory dinosaurs hunted alone, later in the year though a paleontologist found an old national geographic magazine that had an article about Barnum Browns (an old paleon toligist) findings of a group of albertosaurus ( a relative of T-Rex ) that was found near the red deer River in southern alberta. The paleontologist went through Browns archive and eventually found photographs of the site. After days of searching the team found the site and discovered 8 specemins of albertosaurus of all ages it looked like a pack. But there was a problem ther were three way s a group of meat eaters could come together a tar pool but that attracts all sorts of animals not just one species, a flood but the skeletons were intact and together and the albertosaurus being a pack. As the first two were proved wrong the third was concluded correct. But other scientists thought it could be a fluke so the paleontologist had to find another example of packing behavior. Sure enough they found another example in south america when a new species was found and in a group. Infact this dinosaur seems to be the biggest carnivorous dinosaur yet found. Finally most scientists are starting to accept the idea of packing behavior in dinosaurs.
