Dinosaurs lived on the earth millions of years ago even before the human life came into existence. They belong to the mezosoic era. The Dinosaurs are reptiles and most of them hhed from eggs. Predominantly the dinosaurs are herbivorous and fed on plants. Some kinds were carnivores also. Some dinosaurs were 100 ft long and abt 50 ft tall. They are land dewellers and never lived in water. There are no concrete proofs on how the dinosaurs sounded or how they mated. The fossils are found all over the world. They had thick bumpy skin. Its believed that they became extinct because of the environmental changes due to an asteroid that hit the earth. Its very difficult to acertain the sex of the dinosaur from its fossils.
