Dinosaur Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Triassic period. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the Cretaceous-Paleogene extinction event led to the extinction of most dinosaur groups 66 million years ago.

The Pangaean continent breaks into many parts. About 35% animal die and extinct. Primitive dinosaurs were extinct too, but remaining dinosaurs evolved to be more adaptive in the next era, the Jurassic Era. This extinction made dinosaurs as the dominant , abundant and diverse creatures to “rule” the Earth for the next 150 million years. Here are the complete list of Dinosaurs that lived in Triassic Period. ( Source: Wikipedia) A

ERA OF THE DINOSAURS Cretaceous period: 145–65 million years ago Dinosaurs roamed the planet for about 165 million years, during a time in the Earth’s history called the Mesozoic Era. It is difficult to imagine how long this was, until we compare it with ourselves: humans have lived on Earth for less than two million years.

Dinosaur Extinction for Kids Dinosaurs became extinct about 65 million years ago at the end of the cretaceous period (see what cretaceous dinosaurs were around at this time). About 70% of all animal life on earth died out. Scientists call it a mass extinction – it wasn’t the first mass extinction in earth’s history and it probably won’t be the last! Having existed for 165 million years, why did dinosaurs die out? There are many different theories about why this happened.

- The age of the first humanoids : About 400 millions years ago, life left its watery womb and began to develop by selective mutation on terra firma. 165 million years ago, the era of the dinosaurs began, some were vegetarians, others dangerous carnivores ! After 100 million years of supremacy, the dinosaurs disappeared from our planet, at the end of the Cretacean era. Their disappearance coincided with the first period of glaciation.

Barney the Dinosaur The Dinosaur extinction and Barney's survival (65,000,000 BC-1975) Edit. Around 65,000,000 BC, most of the other dinosaurs (except for one) died after a meteor shower struck Earth. However, the only dinosaur that survived the explosion was of course Barney. Although Barney survived, he was still attacking mankind for millions of years.

- Anaplasmosis. Anaplasmosis is a disease caused by infection of the bacterium, Anaplasma phagocytophilum. In the eastern United States, the disease is spread by the bite of an infected black-legged tick, Ixodes scapularis, commonly known as the deer tick.This is the same tick that can transmit Lyme disease.Anaplasmosis is also known as human granulocytic anaplasmosis (HGA) and can be similar to another tick-borne disease, ehrlichiosis. However, these are distinct diseases that are transmitted by different ticks.naplasmosis is a disease caused by infection of the bacterium, Anaplasma phagocytophilum.

What century the dinosaurs roamed the earth? Dinosaurs roamed the earth for around 180 Million years. They first appeared during the begining of the Mezoic Era, approximately 240 million years ago, and were wiped out at the end of Mezoic Era, approximately 75 million years ago, although some modern speicies may be descendants of dinosaurs.inosaurs existed from roughly 220 to 65 million years ago. The first Homo sapiens (modern humans) came into existence 250,000 years ago. This would mean that dinosaurs preceded humans by over 64 million years.

- The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs’ food supply.

Did early man exist at the same time as dinosaurs? Dinosaurs are alive and well, and are all around us. Birds represent the only dinosaur lineage that survived the Cretaceous - Palaeogene (K-Pg) mass extinction event approximately 66 million years ago. I will, therefore, assume that your query is about non-avian dinosaurs living with humans.
