The few rare species that still exist have almost become extinct due to man's selfish and destructive behaviour. Although these animals are dinosaurs, they are very much alive today. They can be found in our modern world, often on the outskirts of major cities. Prehistoric dogs are thought to be distant relatives of the well known dinosaur Thrinaxodon , an early prehistoric mammal which lived during the Mesozoic era about 245 million years ago. Recent evidence suggests that Prehistoric dogs are genetically similar to many modern breeds of dog and many of their behaviours are more dog-like than most dinosaurs.
Prehistoric dogs are amongst the most timid of animals.
They are exclusively nocturnal and have very little contact with man. They are omnivorous scavengers, some have even been known to catch flying insects. Prehistoric dogs have excellent powers of disguise , being able to blend in with the most diverse surroundings and they appear to be almost invisible to all but the professionally trained observer. Many scientists are skeptical and still refuse to acknowledge their existence. Very little photographic proof has been produced and the tracks left by the animals are often attributed to wolves.
