Most paleontologist agree that dromeasaurs(a.k.a. raptors) of Jurassic Park fame hunted in packs to bring down large prey. However, another theropod(meat-eating dinosaur) may have also hunted in packs. The dinosaur Allosaurus, which lived before the raptors may have hunted in packs.
Fossil beds of Late Jurassic Age where Allosaurs are found, contain bones of some of the largest and most formidiable animals to ever walk the earth. Large sauropods(brontosaurs) like Apatosaurus, Brachiosaurus, Camasaurus, and Diplodocus, and armoured Stegosaurs were prey items for the allosaurs. However a solitary allosaur probabley could not most likely bring down a huge sauropod or stegosaur. These theropods may also relied on numbers to bring down the large sauropods and armed stegosaurs, much like a pack of wolves or African wild dogs do.
Possible fossil evidence for allosaur pack hunting, can be found at Cleveland Dinosaur Quarry in central Utah. Here vast numbers of allosaurs of all different ages were caught in death trap similar to the La Bera Tar Pits in Los Angeles. Along with them were bones of sauropods and stegosaurs, and the smaller camptosaurs. However, the allosaur bones are the most common fossil in the deposit. According to some paleontologist this is indeed good evidence for pack hunting for allosaurs. Similar fossil beds containing "packs" of raptors have been found in Montana, and Phil Currie a theropod expert from the Royal Tyrell Museum in Alberta. Has recently found a large bonebed containing what he thinks are a "pack" of tyrannosaurs known as Albertosaurus. What do you think? Could allosaurus very well have been a pack hunter? I look foward to reading your comments.
