The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
Long-necked sauropod dinosaurs and Coelophysis, one of the earliest theropod dinosaurs, evolve. First mammals. c. 214 Ma - Plateosaurus, a basal sauropodomorph or so-called "prosauropod" evolves in what is now Central and Northern Europe, Greenland and North America; c. 210 Ma – Earliest elasmosauridae.

A study aiming to quantify the habitat of latest Cretaceous North American dinosaurs, based on data from fossil occurrences and climatic and environmental modelling, and evaluating its implications for inferring whether dinosaur diversity was in decline prior to the Cretaceous–Paleogene extinction event, was published by Chiarenza et al ...
Skeletal mount of the Tyrannosaurus holotype.. This timeline of tyrannosaur research is a chronological listing of events in the history of paleontology focused on the tyrannosaurs, a group of predatory theropod dinosaurs that began as small, long-armed bird-like creatures with elaborate cranial ornamentation but achieved apex predator status during the Late Cretaceous as their arms shrank and ...
"I'm excited for my friends to see the film," one of the kids said. "They don't believe me that I found a T. rex."
A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
An outcrop of the Cloverly Formation. The Crow people and other Native American groups inhabiting Montana used to use rocks from the Cloverly Formation to make red pigments. . Since the red pigments are richest in the same layers of the formation that preserve dinosaur fossils, it is likely that Native Americans encountered Deinonychus fossils long before scientifically trained paleontolog
