In the record-breaking heat of a Texas summer, a remarkable discovery has emerged from the arid landscape of Dinosaur Valley State Park, just south of Dallas.
Unearthed by a group of dedicated volunteers, these newly exposed dinosaur tracks, believed to be around 110 million years old, have astounded paleontologists and visitors alike.
A Prehistoric Treasure Trove
Paul Baker, the retail manager at Dinosaur Valley State Park, has been working with dinosaur tracks for years. But even he was taken aback by the sheer magnitude of this find. "I've never seen this many dinosaur tracks before," Baker tells CNN.
CNN reports that these newly discovered tracks are believed to have been imprinted by sauropods and theropods that roamed this region approximately 113 million years ago.
Dinosaur enthusiasts and tourists typically flock to this park to fish, swim, and kayak in the now-dry Paluxy River. However, as water levels receded this summer due to a severe heatwave that now covers over a third of Texas, more ancient history was unveiled.
Unearthing the Past
Glen Kuban, a veteran in the field of paleontology who has been studying the Paluxy dinosaur tracks for over four decades, saw this dry spell as an opportunity to expand their knowledge.
With the help of dedicated volunteers from the Dallas Paleontological Society, Master Naturalists, and the Friends of Dinosaur Valley State Park, he set out to uncover these hidden treasures.
But it is not as simple as it may sound. Even when the river is dry, the tracks are typically buried under layers of gravel, sand, and dried mud. Removing this sediment to reveal the tracks is a laborious process that takes many days if not weeks.
Drought Unveils Giants
The tracks recently unveiled are believed to belong to two distinct dinosaur species.
One is the Acrocanthosaurus, a massive carnivore weighing up to 7 tons. It walked on two legs, leaving behind the distinctive imprint of its three-toed feet.
The other is the Sauropodseiden, also known as Paluxysaurus, an enormous long-necked herbivore estimated to weigh a staggering 44 tons. Its tracks resemble bulbous-shaped impressions akin to elephant footprints.
One remarkable find is a "double track," possibly representing two overlapping Acrocanthosaurus tracks.
A Time Capsule in Stone
During the Cretaceous Period, the area where Dinosaur Valley State Park now stands was submerged in a shallow sea. Over millions of years, the sediment solidified into limestone, preserving the dinosaur tracks for eons.
Today, the sediment and water of the Paluxy River continue to protect these priceless relics, but the inexorable erosion of time will eventually take its toll.
Challenges
Despite the excitement surrounding this discovery, it has not been without its challenges. The limestone in the riverbed, exposed to relentless Texas heat, has reached scorching temperatures of up to 126 degrees Fahrenheit (52 degrees Celsius).
Volunteers and researchers have had to brave these harsh conditions to document and study the tracks.
