One of the most famous dinosaurs ever, the Archaeopteryx lived in the Late Jurassic around 150 million years ago, in what is now southern Germany.  It had sharp teeth and claws but with its miniature size (roughly the size of modern raven) and an estimated weight of just about 1 kg (2.2 lb), this dinosaurs would be absolutely harmless to humans.

The Mimni was a small herbivorous quadrupedal armored ankylosaurian that lived during the early Cretaceous Period of Australia (about 119 to 113 million years ago). It was estimated to be about 3 m (10 ft) long and weigh in some 300 kg (660 lb), which was a tiny size for a dinosaur living in this era.

Nicknamed the “shovel tusker”, the Platybelodon looked like a modern day elephant with a flat protrusion comparable to an elongated duck’s bill. With this kind of appearance, the Platybelodon would hardly be considered a scary dinosaur. Moreover, it was an herbivore that fed on aquatic vegetation.



CompsognathusSource: wikipedia.org, image: https://commons.wikimedia.org/wiki/File:Compsognathus_BW.jpg

One of the smallest dinosaur species, the Compsognathus was a small, bipedal, carnivorous theropod dinosaur that lived about 150 million years ago. Some sources suggest it was the size of a chicken while others claim it might have been slightly bigger but either way – the Compsognathus was definitely not a scary dinosaur.



PterodaustroSource: wikipedia.org, image: https://simple.wikipedia.org/wiki/Pterodaustro

The Pterodaustro is a pterosaur that used to live in South America, some 105 million years ago. This ancient creature had about a thousand bristle-like teeth protruding from its lower jaw but it used the teeth only to filter plankton and small crustaceans as it waded through shallow pools. It had an adult wingspan of approximately 250 cm (8.2 ft), about the size of some modern vultures’ wings span.
