How did dinosaurs escape danger?

When threatened, animals will try to avoid a fight, and dinosaurs probably behaved much like other animals. Gallimimus was one of the fastest dinosaurs, possibly sprinting at speeds of up to 50 mph (80 km/h) to outrun predators. Other dinosaurs found different ways to keep out of harm's way. Some developed skin that was colored and patterned to blend in with their environments. Others kept to the safety of the herd. A few dinosaurs could even

Was there safety in numbers?

Dinosaurs living in herds would probably have been much safer than those that lived alone. If a herd of Triceratops was being stalked by a predator, for example, the adults could threaten to charge, while keeping their young well inside the group. Triceratops may also have been able to run at speeds of 15 mph (25 km/h).

Did dinosaurs use camouflage?

However, it is highly likely that many dinosaurs would have skin colors and patterns that helped them to merge with their environment. A dinosaur living in scrubland, such as Velociraptor, may have been any one of a variety of colors.
