The smallest dinosaur in Jurassic period is Compsognathus, Microraptor, Parvicursor and Caenagnathasia. The picture represents Compsognathus dinosaur. The Microraptor is a bird type dinosaur. The Compsognathus lasted 62 million years long in Jurassic period. The size of the Compsognathus is just like our modern hen. It seems like an undressed hen. It ran on two back legs. The speed is about 25 miles per hour. The tail of the dinosaur is long than the body. It weighs up to 10 pounds. Due to its tiny structure, it runs fast. The teeth are so sharp to chew and eat. The head of this type was probably the size of our palm. It has no hair. Hence it makes its body warm and heat. If the air was to be cold it would make it hard for him to run fast, and if it could not move, the bigger animals would eat him all up. It’s a carnivorous. The fossils found in Germany, which is 89cm long and in France with 125cm.
