The fossil's markings place it as existing during the Paleozoic era, between 500 and 251 million years ago.
Titanosaurs, thought to have been among the largest animals to walk the Earth, may have lived longer ago than previously thought.
The creatures had squishy bodies that have long since decayed away, and they lack bones or shells that would remain fossilised.
All the early dinosaurs appear to originate in modern-day South America, some 230 million years ago, after which they moved North.
The bird fossil includes a nearly complete skull hidden inside a nondescriptive rock and dates back more than 66 million years ago.
While birds, crocodilians and many dinosaurs laid hard-shelled eggs, the Antarctic egg had a soft, parchment-like shell.
Asteroid, climate change is not responsible for the mass extinction that took place 215 million years ago
This mass extinction is termed as the Adamanian-Revueltian turnover, which saw a “decline in diversity among crocodylian-line archosaurs and the extinction of several taxa”.
The study could help geologists and climatologists fine-tune records of past temperatures, piece together a more accurate climate record.
The spread of modern humans out of Africa has caused a sixth mass extinction, an event that has last more than 40,000-years.
The body of the extinct horse species was found in perfect condition & scientists are hoping to clone it.
Humans are prove to be ultimate generalists owing more to technology than evolution.
We found microscopic shark teeth right beside bones of the largest predators of all time: Researcher.
Among them are major fossil finds, a reptile ancestor & a controversy that could rewrite man's history.
Sauropod species were the biggest creatures ever to walk the planet, reaching up to 33 to 34 meters.
The fossil shows the evolution of bony fish back then — a completely new way of life: Researcher.
Majority of fish found by researchers in the study came from aquaculture, not local fishing.
The 'elephant bird' belonged to the same family of flightless birds as the kiwi, emu & ostrich today.
The fossil proves that animals abundant millions of years earlier than previously thought: Study.
Primitive hominids may have lived in Africa at the same time as humans, researchers said Tuesday, in new findings that could change the understanding of human evolution.
