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.

As many of us face the drudgery of a Monday morning commute and a day holed up at work, it’s almost painful to think of beautiful, far-off lands and breathtaking views. And yet, this is what Google is inviting us to do with today’s interactive Doodle. Head to the search engine’s homepage and you’ll find a slideshow in the style of an illustrated scrapbook, teaching readers all about the Appalachian Trail. The iconic trail is the longest hiking-only footpath in the world, spanning more than 14 US states and 2,190 miles, as it meanders across dense forests, rushing rivers, and soaring mountains. And if you're wondering why the tech company has decided to pay tribute to the famous landmark today, it's because on 2 October 1968, America’s National Trails System Act established the Appalachian Trail as one of the country’s first National Scenic Trails. Hiking the full length of the path can take between five and seven months to complete and requires careful planning. And yet, as Google’s slideshow points out, around 3,000 people attempt this staggering feat each year, with a total of three million people visiting the trail annually. The route has served walking enthusiasts for nearly 100 years, having been completed in 1937. It was first proposed by conservationist Benton MacKaye in 1921, with his original plan calling for a stretch of several self-sustaining agricultural camps along the way, Google notes in its blurb for the Doodle. Then 10 years later, a hiker named Earl Shaffer became the first person to make it from one end to the other. Since then, more than 14,000 people have joined him in completing the trek. Perhaps inevitably for such a legendary trail, it has engendered a number of unique traditions. These include being given a “trail name” by fellow hikers and eating two litres of ice cream at the route’s mid-point. However, the trail’s oldest and most important tradition is to leave it just as you found it so that everyone can enjoy the same natural beauty.
