Ancient Animals - *Dickinsonia*: A genus of extinct animals that lived around 558-555 million years ago during the Ediacaran period. - *Trilobites*: Ancient arthropods that existed from the Cambrian period (around 521 million years ago) to the Permian-Triassic extinction event (around 252 million years ago). - *Anomalocaris*: A genus of extinct animals that lived during the Cambrian period, around 515-505 million years ago. - *Hallucigenia*: A genus of extinct animals that lived during the Cambrian period, around 505 million years ago. - *Pikaia*: A genus of extinct chordates that lived during the Cambrian period, around 505 million years ago.
Early Life Forms - *Microorganisms*: Single-celled organisms like bacteria and archaea are believed to have existed on Earth for at least 3.5 billion years. - *Stromatolites*: Ancient structures created by microbial communities, dating back around 3.5 billion years.
Dinosaurs and Other Prehistoric Creatures - *Dinosaurs*: Dominated Earth's landscapes during the Mesozoic era, which lasted from around 252 million to 66 million years ago. - *Mammoths*: Large relatives of modern elephants that lived during the Pleistocene epoch, around 2.6 million to 11,700 years ago.
These ancient animals and early life forms played a significant role in shaping the history of life on Earth.
