King Dinosaur: Trinity, 67 million-year-old Tyrannosaurus-Rex, to go for sale in Switzerland
The skeleton of a giant Tyrannosaurus Rex, named TRX-293 Trinity, will go under the hammer on 18 April in Switzerland’s Zurich. The T-Rex fossil, made up of three specimens excavated from 2008 to 2013 in the United States, is only the third to be auctioned and the first such in Europe
Explained: The special bones that allowed dinosaurs to fly
According to a recent study, dinosaurs as large as buses and five-storey buildings survived because of their unique bones, which are hollow filled with little air sacs
Three-toed dinosaur footprint discovered in ruins of 600-year-old Spanish convent
After closely examining the stone, the scientists drew a conclusion that this was a dinosaur footprint. The researchers believed that the footprint resembled those of theropods, a family of medium-sized carnivorous dinosaurs
Toys for the rich: Do multimillion-dollar dinosaur auctions erode trust in science?
More and more palaeontologists are ringing alarm bells about high-profile auctions in which dinosaur fossils sell for outrageous sums. The most recent example involves a 77-million-year-old ‘Gorgosaurus’ skeleton that Sotheby’s sold for over US$6 million in August 2022
Dinosaurs were in decline even before extinction, claim Chinese Academy of Sciences researchers
The researchers studied over 1,000 fossilised dinosaur eggs and eggshells from the Shanyang Basin in central China and obtained detailed age estimates of the rock layers by analysing and applying computer modelling to over 5,500 geological samples
Dinosaur footprints dating back 200 million years discovered on Wales beach
The latest findings reveal that the footprints are unique and not common worldwide; further research could disclose interesting facts about Triassic life in the UK
Dinosaur species were already in decline much before meteor strike, says study
The Chicxulub meteor crashed into the Yucatan peninsula around 66 million years ago but the team found that dinosaur species decline began around 76 million years ago.
Mexican paleontologists identify new 'talkative' dinosaur, believed to have existed nearly 73 million years ago
The animal is called Tlatolophus galorum. Its tail was discovered first, in the General Cepeda area of the northern state of Coahuila in 2013.
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
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
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
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
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
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
Around 66 million years ago, a mass die-off called Cretaceous–Paleogene extinction event, put an end to the reign of dinosaurs.
