About 65 million years ago, different types of dinosaurs were killed and some types of dinosaurs were survived. Dinosaurs were first appeared in the Triassic period around 243 million years ago. The different types of dinosaurs ate, lived, survived differently. So, we are going to discuss the past locations, the food they eat, and the specification of different types of dinosaurs.
Different Types of Dinosaurs:
According to experts, roughly 700 species are discovered and named according to their specifications or structure. Following are different types of dinosaurs in a list:
Theropods:
Theropods lived in the Carnian Age of the late Triassic about 221 million years ago. Theropods were reptile-hipped dinosaurs. They were hollow bones and three-toed limbs. Theropods could walk on two feet. They were carnivores from their ancestors but they evolved themself into herbivores, omnivores, and insectivores, etc.
Nyasasaurus was the first species of dinosaurs on Earth. It also looks like a theropod but there is no evidence of Nyasasaurus to be a theropod.
Theropods were able to swim deep in water. Theropods were flesh-eating dinosaurs. There are different types of dinosaurs in the theropods species. All theropods were ancestrally flesh-eaters but some of them evolved in herbivores, and carnivores, etc.
Theropods lived about 232 million years ago. The first therapod’s fossils were found in Northwestern Argentina which was about 230 million years old. The largest-ever theropod was 9ft high and its weight was around 120kg. The smallest theropod was “Troodontid Anchiornis Huxleyi”, 1ft in length and 110 grams in weight.
Sauropods:
Sauropods were also lizard-hipped dinosaurs as theropods. They were long-necked, small heads, and long tails dinosaurs. Their heads were small as compared to the size of their body. They have lived around 215 million years ago in the Late Triassic and late Cretaceous.
Sauropods name Sauropoda means “Lizard Foot”. These dinosaurs were very large. Their complete fossils have not been found yet.
From other different types of dinosaurs, sauropods were plant-eating dinosaurs (Herbivores). They use to walk on four legs.
The sauropods were giant dinosaurs. Even the smallest sauropod was 20 feet long. The longest sauropod was 33 to 34 meters long.
Sauropods had an “air sac” system which reduced the overall weight of massive necks. Sauropods could also swim. Nigersaurus was a sauropod with 500 teeth who were changes his teeth after 15 days.
Ornithischians:
Ornithischians were herbivores with a pelvic structure similar to birds. Two groups of this specie were survived the extinction event. These groups are Ankylosaurus and Cerapods. Ornithischians contain dinosaurs with horns and armored dinosaurs.
Dinosaurs with Horns:
Ceratopsia was a group of herbivores and dinosaurs with horns. They were from the generation of ornithischians. They lived 161 million years ago and were killed in the extinction event, 60 million years ago. They were 1 to 9 meters in height and 23 to 9,100 kg in weight.
Centrosaurus and Triceratops are well-known dinosaurs with horns.

The armored dinosaurs had spikes on their back to protect themselves from predators. Armored dinosaurs had not been poisoned to kill the prey but they had armor and shield (spikes on back) to protect themselves from other predators.
Interesting Facts About Different Types of Dinosaurs:
- In Jurassic Park, Dilophosaurus were theropods who armored themselves by spitting poison towards their predator. Almost all people considered it as truth but it is a fake concept.
- Dilophosaurus had no expandable neck frill.
- Theropods are mostly herbivores but Ornithischia was a carnivore.
- Dinosaurs had not any weapon like poison but they had armor to protect themselves.
- There were three different types of dinosaurs. Theropods, Sauropods, and Ornithischians.
- The smallest ever sauropod was 500 kg in weight which is equal to Grey Whale (newborn).
