Divers in Mexico have discovered Megalodon teeth in a flooded inland cave and the findings have confirmed scientific beliefs. Megalodons were absolutely gigantic prehistoric sharks that reached sizes of up to 50 feet long. They dominated the oceans before going extinct around 3.6 million years ago. Scientists are interested in studying fossils of the huge sea creature, with the animal's teeth proving the most abundant type of fossil to be found today. Teeth fossils were found in Mexico by speleologist (cave specialist) and photographer Kay Nicte Vilchis Zapata and fellow speleologist Erick Sosa Rodriguez while diving in a newly discovered sinkhole in Cholul in 2019. The cenote is 400 meters long and 28 meters deep and located inside were fifteen teeth fossils from various shark species. They also discovered human remains and a vertebrae fossil that potentially belongs to an ancient species. A total of 13 of the 15 teeth fossils belonged to three different species of shark – one being the megalodon (Carcharocles megalodon), while the other two species were the mackerel shark (Isurus oxyrinchus) and the sawshark (Pristiophoridae). Zapata told local media at the time: “We were looking at the wall and suddenly I saw a little something, I went closer and I saw that it was a tooth, that was the first and apparently it belonged to a sawshark.” Experts believe the geological timescale of the megalodon teeth lies anywhere between 2.5 million to 5 million years old. Speleologist Sosa Rodriguez said: “It is just proof of what scientists have already studied and written about; what kind of wildlife lived here millions of years ago when this was part of the sea.” Scientists have suggested that the megalodon’s warm body temperature may have been the reason for its extinction. There is some thought that the megalodon was able to maintain a body temperature around 7 degrees centigrade warmer than the water around it, but ultimately this may have been its downfall. Randy Flores, a UCLA doctoral student and fellow of the Centre for Diverse Leadership in Science, explained: “Maintaining an energy level that would allow for megalodon’s elevated body temperature would require a voracious appetite that may not have been sustainable in a time of changing marine ecosystem balances when it may have even had to compete against newcomers such as the great white shark.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Apple’s upcoming iPhone 15 may feature a new stacked battery design that is commonly used in electric vehicles, a new report has suggested. The new handset models expected to be launched in September may have their battery components stacked on top of each other, according to a seasoned leaker who goes by the username RGcloudS on Twitter. This design may lead to battery components being more tightly packaged, likely offering a higher energy density for the new iPhones. An earlier report from ITHome had suggested that these next-gen iPhones could feature as much as a 15 per cent boost to battery life. Many experts said battery packs are one area where there is an opportunity for Apple to explore more innovation. While cameras and display screens have gotten better over the years, there have only been marginal improvements in battery life across models. The development currently seen in the existing iPhone 14 battery life is also not as significant as that seen with the previous model iPhone 13. The leaker, however, pointed out that the new battery technology design for iPhone 15 remains “limited”, indicating that it may not be fully implemented as the handsets roll out for the public. There have been a number of rumours so far regarding design upgrades for the iPhone 15. Some leakers claim the new iPhone could ditch the lightning port in favour of USB-C for the first time and that Apple might remove the mechanical volume and power buttons on its handsets and replace them with solid-state ones. Rumours also suggest the iPhone 15 could feature a new chip to support Apple’s upcoming Vision Pro VR headset and allow the phone to work as part of a “more competitive ecosystem”, leaker Ming-Chi Kuo had said. This latest rumour comes on top of several other features Apple announced for its upcoming iPhone at its Worldwide Developer’s Conference last month. At the conference, the tech giant said iPhone 15 upgrades would include a range of new tools from one for journalling and AirDrop updates to live transcription in voicemail and a new standby mode to turns the iPhone into a smart display.
