Introduction:
The news topic “T. rex’s ancestors may have walked from Asia to North America” has drawn international attention, with various media outlets providing diverse insights, historical context, political stances, and on-the-ground developments. Below is a curated overview of how different countries and media organizations have covered this topic recently.
Quick Summary:
- T. rex likely crossed a land bridge from Asia more than 70 million years ago. Study also explores the evolutionary rise of megaraptors, suggesting that climate played a significant role in their development. Global temperatures peaked around 92 million. years ago, but a cooling trend soon followed. This climatic shift coincided with the rapid growth in size of tyrannosaurids and megar.aptors. Despite the cooling climate, Morrison’s team found no direct link between temperature and body mass. Instead, they suggest that climatic shifts may have indirectly fueled gigantism by altering predator-prey dynamics. The study was published in the journal Royal Society Open Science. The research was led by Cassius Morrison, a PhD student in Earth Sciences at UCL, and published by the journal Earth Sciences.
- Dinosaurs might still be roaming the planet today if the Chicxulub asteroid hadn’t hit 66 million years ago. Signs of decline in the years leading up to the impact were due to fossils being less likely to be discovered. Researchers say their analysis of fossils shows populations weren’t on the decline before the extinction event. They focused on four groups that included the armored Ankylosaurus, the popular Triceratops, the duckbilled Edmontosaurus and the king, Tyrannosaurus Rex. They estimated how much of North America the dinosaurs likely occupied at four different times in those 18 million years prior to the asteroid impact at the end of the Cretaceous period. Researchers examined the historical timeline of more than 8,000 fossils in the 18. million years leading before the impact. The study was published earlier this month in the journal Current Biology.
- The direct ancestor of Tyrannosaurus rex would have arrived in North America after crossing a land bridge from Asia, a new study says. The finding tracks with past research that suggests T. rex was more closely related to the large carnivore Tarbosaurus in Asia. At the time, the area would have been home to temperate rainforests, with a climate somewhat similar to British Columbia today, the UCL team says. It is the latest to weigh in on the fierce debate among paleontologists over the origins of the king of the dinosaurs. fossils of these T.Rex ancestors may still remain undiscovered in Asia, the study says, suggesting they may not have been preserved in the fossil record, as previously thought. The team also found that tyrannosaurids s also could not have preyed on herbivorous dinosaurs like lions.
