Earth was home to billions of T-rex over lakhs of generations, suggests new study

The estimate comes from studies of well-preserved T rex fossils – 32 of them, with enough material to determine they were adults.

Remains of massive plant-eating lizard in Argentina likely the largest, oldest ever found

Titanosaurs, thought to have been among the largest animals to walk the Earth, may have lived longer ago than previously thought.

Teen angst? T-Rex, other large dinosaurs out-competed smaller rival species, study finds

Dinosaurs were not particularly diverse: there are only some 1,500 known species, compared to tens of thousands of modern mammalian and bird species.

Comet from solar system's edge triggered a winter that killed the dinosaurs 66 mn-years-ago: Harvard study

Comet from solar system's edge triggered a winter that killed the dinosaurs 66 mn-years-ago: Harvard study

These long-period comets take about 200 years to orbit the Sun and we can expect similar impacts every 250 million to 750 million years.

Crocodiles have remained largely unchanged since the last 200 million years

Crocodiles have remained largely unchanged since the last 200 million years

It seems that crocodiles arrived at a body plan that was very efficient and versatile enough that they did not need to change or evolve in order to survive.

Climate change reference curve spanning 66 mn years made using ocean sediments

The reconstruction and analysis show that Earth's climate can be grouped into discrete states, based on changing greenhouse gas levels and growth of polar ice sheets.

Fossilized leaves, around 150-200 million years old, found in Jharkhand's Dudhkol mountain

The geologists believe that they might even find fossilised dinosaur eggs when they conduct a further excavation.

The Thing: Second-largest fossil egg ever found, from Antartica has scientists bewildered

While birds, crocodilians and many dinosaurs laid hard-shelled eggs, the Antarctic egg had a soft, parchment-like shell.

Asteroid that killed dinosaurs hit Earth at 60 degrees, maximising the amount of climate-changing gases that entered the atmosphere

Asteroid that killed dinosaurs hit Earth at 60 degrees, maximising the amount of climate-changing gases that entered the atmosphere

It released sulphur in the air and started a “nuclear winter” that not only wiped out dinosaurs but caused 75 percent of life on Earth to go extinct.

Asteroid, climate change is not responsible for the mass extinction that took place 215 million years ago
science

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”.

Fossil footprints in South Africa show dinosaurs lived in land of fire, 183 million years ago
science

Fossil footprints in South Africa show dinosaurs lived in land of fire, 183 million years ago

During this period, there were mass extinctions, especially in oceans, caused by gases from the lava that flowed onto land.

Australia wildfires: Mass extinction events that reshaped the Earth, were caused by bushfires
science

Australia wildfires: Mass extinction events that reshaped the Earth, were caused by bushfires

Around 66 million years ago, a mass die-off called Cretaceous–Paleogene extinction event, put an end to the reign of dinosaurs.

Treasure trove of fossil reveal post-apocalyptic landscape after an asteroid hit Earth

Mammals had lived in the large shadow of the dinosaurs, never getting bigger than a small dog until the mass extinction.

Most bird-like dinosaur ever flapped its wings like a raven, lived in the Jurassic

The discovery is likely to fuel the debate over how birds & dinosaurs developed the ability to flap their wings.
