Bodies of water have been drying up as a brutal drought grips portions of the globe this summer, exposing submerged World War II artifacts in Europe, multiple sets of human remains at Lake Mead south of Las Vegas, and even an entire hamlet in Spain.The most recent discovery as water levels drop: dinosaur footprints in Texas.
According to Stephanie Garcia, a spokeswoman for the Texas Parks and Wildlife Department, severe drought conditions at Dinosaur Valley State Park, about 60 miles southwest of Fort Worth, exposed dinosaur footprints from about 113 million years ago that were previously concealed beneath the Paluxy River. Theropods, or bipedal dinosaurs with three toes and claws on each limb, Acrocanthosaurus is the species whose tracks were found this month.As an adult, the dinosaur would have reached 15 feet tall and weighed about seven tons. According to researchers, they would have left their prints in sediment that later calcified into limestone.
"The river dried up completely in most spots due to the extreme drought conditions this past summer, enabling for more tracks to be unearthed here in the park," Ms. Garcia said in a statement. "These newer routes are beneath water and are filled in with sediment, making them buried and less visible, under typical river conditions."
This week's rain is likely to bury the rails once more. But the discovery intrigued both scientists and the general public, if only momentarily.
Tracks are shielded from erosion and weathering by being buried beneath sedimentary layers, according to Ms. Garcia.
Sauroposeidon proteles, a long-necked, small-headed sauropod, left other traces at Dinosaur Valley State Park. In its full form, this creature would have stood 60 feet tall and weighed 44 tons.The traces were discovered on Saturday by vertebrate paleontologist and retired Southern Methodist University professor Louis Jacobs. According to him, the previously unknown trackways were joined with the newly discovered ones, adding up to roughly 150 dinosaur steps.
He remarked, "Those tracks are extraordinary because they are deep. "The toenails are visible. There are several types and there are various types.
The prints, according to Mr. Jacobs, suggested there might be more that has yet to be found. More things will be exposed as the river erodes, but some things will also be lost.
In 1938, paleontologists from the American Museum of Natural History in New York City recovered dinosaur footprints from the Paluxy River.
According to James Farlow, a vertebral paleontologist and adjunct biology professor at Purdue University Fort Wayne, similar trails have been discovered in South America and British Columbia.
He claimed that for many years, the river and park have taught scientists about the habits of dinosaurs. However, the weather frequently has the final say in the finds, with frozen pebbles in the winter fracturing the traces.
The Glen Rose Formation, a sedimentary rock formation composed primarily of limestone that was produced between 105 and 110 million years ago, is where the footprints were discovered, according to Mr. Farlow.
Mr. Farlow remarked that Texas was endowed with a wealth of fossil finds, including both dinosaur skeletons and footprints.
It's a resource that is constantly being renewed but also constantly being destroyed, he continued.
Following a time of excessive heat and hazardous wildfires, Texas is experiencing extreme weather, with some areas of the state experiencing droughts and other areas seeing flash flooding.
The top elected official in Dallas County, Judge Clay Jenkins, declared a state of disaster in the area after certain areas of the Dallas-Fort Worth region received more than 13 inches of rain from Sunday into Monday. The Texas Division of Emergency Management was instructed by Governor Greg Abbott to mobilize resources to assist flood-affected people.
