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.
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The segment is set in a whole new era that is way after the dinosaurs's reign. Creatures from the era include Leptictidium, Propalaeotherium, Europolemur, Diplocynodon, Bemalambda, Archaeolambda, Entelodon, Hyaenodon, Paraceratherium, Thylacosmilus, Doedicurus, Promacrauchenia, Alcidedorbignya, Mayulestes, Asiocoryphodon, Smilodon, Tingamarra and Embolotherium (named as Brontotherium in ...
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 ...
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 ...
"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."
As the Stegosauria originally included all armored dinosaurs, Romer's distinction marked the beginning of the modern use of the name to refer to the plate-backed and spike-tailed dinosaurs. [6] Type specimen of Scolosaurus. 1928. Nopcsa described the new genus Scolosaurus. [21] Charles Sternberg described the new genus and species Edmontonia ...
