What is the smallest dinosaur in the world?

The smallest known dinosaur in the world is currently the Oculudentavis. This tiny dinosaur was discovered in a piece of amber, reaching approximately from head to tail five centimeters long.

It only weighed around two grams, making it about the size of the smallest bird alive today Bee elf, a species of hummingbird. Its name means “eye-toothed bird” because its head image is reminiscent of a bird with large eyes and small teeth. That was true for a long time Compsognathus as the smallest dinosaur, but later finds such as Microraptor and now Oculudentavis have fallen well below this ranking.
