What were the biggest and smallest dinosaurs?
Several of these (Argentinasaurus and Amphicoelias) might have been one and a half to two times larger than Brachiosaurus. The smallest dinosaurs were just slightly larger than a chicken; Compsognathus (“pretty jaw”) was 1 m (3 ft) long and probably weighed about 2.5 kg (about 6.5 lb).
What is the smallest dinosaur ever discovered?
The amber-encased fossil was touted as the smallest fossil dinosaur ever found. Known from little more than a peculiar skull, and described early in 2020, Oculudentavis khaungraae was presented as a hummingbird-sized toothed bird—an avian dinosaur that fluttered around prehistoric Myanmar about 100 million years ago.
Which is the smallest of these dinosaurs?
Answer: The smallest dinosaurs yet discovered are: A new, crow-sized theropod, Microraptor was recently found in China. It is about 16 inches (40 cm long) and may be an adult. Compsognathus, a theropod (meat-eater) 2 feet (60 cm) long, from 145 million years ago.
What is the name of the largest dinosaur ever found?

Are dinosaurs still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.

What is the strongest dinosaur in the world?
Researchers on Wednesday said a computer model based on the T. rex jaw muscle anatomy and analyses of living relatives like crocodilians and birds showed its bite force measured about 8,000 pounds (3,630 kg), the strongest of any dinosaur ever estimated.
What is the biggest animal that ever lived?
Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg – that’s about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
