Some herds may have been temporary, however, with the dinosaurs simply congregating temporarily at rich feeding grounds.
Many sauropods may have travelled in herds, as evidence from multiple trackways (fossilized footprints) suggests. The trackways also indicate that the young sauropods travelled toward the center of the herd for protection.
A bonebed of about 100 Styracosaurus fossils was found in Arizona, indicating that they also travelled in herds. Protoceratops bonebeds have also been found. Other ceratopsians, like Triceratops, may have also travelled in herds.
Maiasaura fossils have been found in a huge group of about 10,000 animals. This strongly indicates herding behavior. These Maiasauras were buried in volcanic ash along with a field of nests and eggs. Other duck-billed dinosaurs (hadrosaurs like Parasaurolophus) may have also congregated in herds to feed, nest, and perhaps migrate.
A bonebed of about 20 Hypsilophodon fossils were unearthed together on the Isle of Wight (an island off the coast of southern England).
Several hundred Coelophysis fossil skeletons have been found in Arizona, New Mexico, and perhaps Utah. Adults and juveniles of this meat-eating dinosaur have been found.
and Dryosaurus.
Some meat-eating dinosaurs may have hunted in packs, combining their strength in order to kill very large prey.
The deadly and intelligent Velociraptor may have hunted in packs, attacking even very large animals. Other Dromeosaurids (the most intelligent dinosaurs), like Deinonychus may have also hunted in deadly packs, attacking even huge sauropods and ankylosaurids.
