What led to dinosaurs’ extinction?

Published

An asteroid or comet impact 66 million years ago reignited massive volcanic eruptions in India, and may have contributed to the dinosaurs’ extinction at the end of the Cretaceous period, finds a study.

In the study, scientists from the University of California – Berkeley, report that the million-year sequence of eruptions spewed lava flows for distances of at least 500 km across the Indian continent, creating the so-called Deccan Traps flood basalts that in some places are nearly 2 km thick.

“Now that we have dated Deccan Traps lava flows in more and different locations, we see that the transition seems to be the same everywhere.

“I would say, with pretty high confidence, that the eruptions occurred within 50,000 years, and maybe 30,000 years, of the impact, which means they were synchronous within the margin of error,” said Paul Renne, Professor at UC Berkeley.

“That is an important validation of the hypothesis that the impact renewed lava flows.”

The new dates also confirm earlier estimates that the lava flows continued for about a million years, but contain a surprise: three-quarters of the lava erupted after the impact, according to the study published in the Science journal.

Previous studies suggested that about 80 percent of the lava erupted before the impact.

If most of the Deccan Traps lava had erupted before the impact, then gases emitted during the eruptions could have been the cause of global warming within the last 400,000 years of the Cretaceous Period, during which temperatures increased, on average, about 8 degrees Celsius.

During this period of warming, species would have evolved suited to hothouse conditions, only to be confronted by global cooling from the dust or by climate cooling gases caused by either the impact or the volcanoes.

The cold would have been a shock from which most creatures would never have recovered, disappearing entirely from the fossil record leading to a mass extinction, they explained.

Casino Days Reveal Internal Data on Most Popular Smartphones

International online casino Casino Days has published a report sharing their internal data on what types and brands of devices are used to play on the platform by users from the South Asian region.

Such aggregate data analyses allow the operator to optimise their website for the brands and models of devices people are actually using.

The insights gained through the research also help Casino Days tailor their services based on the better understanding of their clients and their needs.

Desktops and Tablets Lose the Battle vs Mobile

The primary data samples analysed by Casino Days reveal that mobile connections dominate the market in South Asia and are responsible for a whopping 96.6% of gaming sessions, while computers and tablets have negligible shares of 2.9% and 0.5% respectively.

The authors of the study point out that historically, playing online casino was exclusively done on computers, and attribute thе major shift to mobile that has unfolded over time to the wide spread of cheaper smartphones and mobile data plans in South Asia.

“Some of the reasons behind this massive difference in device type are affordability, technical advantages, as well as cheaper and more obtainable internet plans for mobiles than those for computers,” the researchers comment.

Xiaomi and Vivo Outperform Samsung, Apple Way Down in Rankings

Chinese brands Xiaomi and Vivo were used by 21.9% and 20.79% of Casino Days players from South Asia respectively, and together with the positioned in third place with a 18.1% share South Korean brand Samsung dominate the market among real money gamers in the region.

Cupertino, California-based Apple is way down in seventh with a user share of just 2.29%, overshadowed by Chinese brands Realme (11.43%), OPPO (11.23%), and OnePlus (4.07%).

Huawei is at the very bottom of the chart with a tiny share just below the single percent mark, trailing behind mobile devices by Motorola, Google, and Infinix.

The data on actual phone usage provided by Casino Days, even though limited to the gaming parts of the population of South Asia, paints a different picture from global statistics on smartphone shipments by vendors.

Apple and Samsung have been sharing the worldwide lead for over a decade, while current regional leader Xiaomi secured their third position globally just a couple of years ago.

Striking Android Dominance among South Asian Real Money Gaming Communities

The shifted market share patterns of the world’s top smartphone brands in South Asia observed by the Casino Days research paper reveal a striking dominance of Android devices at the expense of iOS-powered phones.

On the global level, Android enjoys a comfortable lead with a sizable 68.79% share which grows to nearly 79% when we look at the whole continent of Asia. The data on South Asian real money gaming communities suggests that Android’s dominance grows even higher and is north of the 90% mark.

Among the major factors behind these figures, the authors of the study point to the relative affordability of and greater availability of Android devices in the region, especially when manufactured locally in countries like India and Vietnam.

“And, with influencers and tech reviews putting emphasis on Android devices, the choice of mobile phone brand and OS becomes easy; Android has a much wider range of products and caters to the Asian online casino market in ways that Apple can’t due to technical limitations,” the researchers add.

The far better integration achieved by Google Pay compared to its counterpart Apple Pay has also played a crucial role in shaping the existing smartphone market trends.
