Dinosaurs are no longer roaming the earth, but their tracks live on. In the foothills on the Front Range of Colorado, a story can be told from pieces of the past left behind.Dinosaur Ridge has been ranked by a panel of esteemed paleontologists as the no. 1 track site in all the U.S. One of those world-renowned paleontologists is Martin Lockley, who has spent his life studying dinosaur tracks.“You're looking at a snapshot of an ancient environment," Lockley says.In an area of just a few hundred square feet, 330 dinosaur tracks have been discovered. However, the land was very different 100 million years ago. Lockley says the giant prehistoric animals weren't a mile high in the Rocky Mountains.They were on the beach at sea level in an environment very similar to present day Gulf of Mexico.“We like to joke and call this beach-front property a 100 million years ago," Lockley says.The soft, wet, sandy land made conditions ideal for preserving tracks."If they're walking on wet sediment, like a beach or a mud flat or the shores of a lake, and it dries out, it becomes hard like concrete," Lockley explains. "And the next time there's a flood washing in more sediment, it will bury those tracks without them being eroded away."Experts believe three different dinosaurs made their mark on this patch of land. Lockley says it's possible they were migrating along what used to be a coast. It's clear the western U.S. was a popular place to be, because there are more than 120 dinosaur track sites from Kansas to Utah. Martin suggests part of the reason is less vegetation in these states means more fossilized rock is exposed.But if there are so many track sites, what makes Dinosaur Ridge the top of all track sites? Executive Director Jeff Lamontagne, with Friends of Dinosaur Ridge, says there was a list of criteria the panel considered."How many tracks there are, the variety of dinosaurs seen in the tracks, the importance of the tracks, the clarity of the tracks, the accessibility and number of visitors," Lamontagne explains.Accessibility is the main reason Dinosaur Ridge has become so highly regarded."It's right outside a major metropolitan area, and there's a major road just a quarter mile from here," he says. "It's easy to see this compared to most other dinosaur track sites in the United States and in the world."People can get so close to the tracks; in some places you can even touch them. Although the tracks have been well-preserved for millions of years, their current exposure to humans and the elements could make them erode over time.Thankfully, with current technology, scientists can scan the surface and re-create it as 3-D permanent record. They also plan to build a cover to protect the land.However, Friends of Dinosaur Ridge believe the hands-on part of the site is important for kids to continue learning about the planet's past. A past that can teach us about topics like climate change, evolution and extinction."We used to think that the dinosaurs all went extinct, but then we realized that some of them survived and evolved into birds," Lockley says.For modern-day humans, Dinosaur Ridge will continue to be an intriguing learning opportunity, reminding people we aren't the only ones to experience life on Earth."It gives you a sense of wonder to imagine these enormous beasts living, playing, dying, a hundred million years ago," Lamontagne says.********************************************If you'd like to reach out to the journalist for this story, email elizabeth.ruiz@scripps.com 3540

COLUMBIA, S.C. – Representatives for former President Barack Obama are demanding a Republican super PAC stop airing an ad that quotes Obama. The commercial in question uses Obama’s words to imply former Vice President Joe bidden supports "plantation politics." The former president's lawyers say that quote comes from his audio book and the statement was made by a barber in a completely different context more than 20 years ago. They 447

Even before the blaze at Notre Dame was extinguished, conspiracy theories and fake news about the fire had ricocheted around the internet.The most egregious examples of disinformation originated in the darker corners of the internet but many found bigger audiences on social media.One prominent conspiracy theory revolved around the claim that the fire had been deliberately started.InfoWars, a fringe website which is known for spreading conspiracy theories, published a story which suggested the fire had been intentionally set.The claim was based on a single erroneous tweet, which was later deleted. The InfoWars story remains online.Paris Prosecutor Rémy Heitz said that while the cause of the fire has not been established, it was likely "accidental.""Nothing shows that it's an intentional act" he said in a press conference on Tuesday.Yet some social media users made claims that went beyond even what was claimed by InfoWars. On Twitter, a fake account made to look like one operated by CNN claimed the fire was caused by terrorism.The account, which was created in April, was only removed several hours after CNN publicly called out Twitter over it.Conspiracy theories about the origin of the fire were also abundant on the internet message board 4chan, where users resorted to using trolling tactics that are designed to aggravate the media.Social media users with big followings promoted the conspiracy theories, with some attempting to blame racial or religious minorities for the outbreak of the fire. One strategy appeared to be the use of old and unrelated articles about Catholic churches being desecrated in France to insinuate that the Notre Dame fire was an intentional act.Other accounts posted an erroneous 2016 article about gas tanks and "Arabic documents" being uncovered near the cathedral.Big social media companies appeared to struggle to contain the spread of the content.A YouTube feature designed to combat misinformation even linked the fire at the Notre Dame Cathedral to the September 11 terrorist attacks. The company blamed the mix-up on its algorithms. 2132

Due to a shortage of certain commonly used blood pressure drugs, the US Food and Drug Administration took the unusual step Thursday of reminding patients that they have access to available -- if tainted -- medicines while a fresh supply of uncontaminated pills is manufactured. 289

CLEVELAND — Police in northeast Ohio says they've collected multiple handguns in the past month that have been modified to turn the firearm into an automatic weapon.In one case, 20-year-old Toriano Leakes, Jr. of Cleveland was indicted on two counts of illegal possession of a machine gun.Bedford Police say the Glock handgun they confiscated from Leaks' car was modified to include a "select-fire auto sear." The device is also sometimes known as a "select fire switch."According to Justin Herdman, a US Attorney in the Northern District of Ohio, the modified handguns can fire 30 rounds in the span of five to six seconds.“It’s a newer thing hitting the internet because people think it’s cool,” said Assistant Bedford Police Chief Rick Suts.“The second you put that on a gun, it violates the National Firearms Act. It makes it a machine gun which is illegal," he said.Federal authorities say they've seen an increase in the modified handguns and they hope to crack down.“We have seen a significant uptick in people trying to acquire these switches manufactured mostly in China,” Herdman said. "...a message is being sent. If you have a machine gun in the Northern District of Ohio, we are going to prosecute you federally."The push is part of Project Safe Neighborhoods, a program aimed at violent crime. 1319
