What is the oldest dinosaur fossil ever found?

Paleontologists have for about 150 years suggested dinosaurs existed in the Middle Triassic, as the oldest dinosaur fossils fit into the Late Triassic period.
A.

What was the very first dinosaur on earth?

The oldest dinosaurs yet discovered date back nearly 230m years to the Late Triassic epoch. Fossils of Herrerasaurus and Eoraptor were discovered in Argentina; both were bipedal carnivores (meat-eaters that walked on two legs), and small in comparison to the giant dinosaurs that would follow.
  • What is the first thing on earth?

    The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
  • What is the strongest dinosaur in the world?

    The Eight Deadliest Dinosaurs
    • Spinosaurus aegyptiacus. Recent research has shown Spinosaurus aegyptiacus is most likely the largest species of carnivorous dinosaur that ever lived, measuring over 50 feet long.
    • Velociraptor mongoliensis.
    • Tyrannosaurus rex.
    • Mapusaurus roseae.
    • Ankylosaurus magniventris.
    • Allosaurus.
  • When was the first dinosaur?

    230 million years ago
B.

What is the earliest known dinosaurs?

A newly-described fossil found decades ago in Tanzania extends the dawn of the dinosaurs more than 10 million years further back in time. Named Nyasasaurus parringtoni, the roughly 243-million-year-old fossils represent either the oldest known dinosaur or the closest known relative to the earliest dinosaurs.
  • What is the closest living thing to a dinosaur?

    Dinosaurs are in the reptile group, which includes turtles, crocodiles, birds, lizards, and snakes. Of these groups of animals, second to birds, crocodiles are probably the closest related to dinosaurs (though they are not considered modern dinosaurs themselves, unlike birds).
  • How did mammals survive the extinction of the dinosaurs?

    This catastrophic impact—called the Cretaceous/Tertiary orK/T extinction event—spelled doom for the dinosaurs and many other species. Some animals, however—including many small mammals—managed to survive. Mammals, in contrast, could eat insects and aquatic plants, which were relatively abundant after the meteor strike.
  • When did the first dinosaurs appear on Earth?

    Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.
