Fossil footprints found in Bolivia reveal dinosaurs’ poor attempts at swimming

Legend once had it that the giant, three-foot paintings scattered in the highlands of central Bolivia came from super-powerful orcs – capable of sinking their lumps into solid rock.

Then the scientists arrived here in the 1960s and put the fear that unknown baby dinosaurs, with two-sided things that were determined more than 60 million years ago, in the ancient streets of Toro Toro, a town and a National Park in the Bolivian Andes.

Now, a group of paleontologists, mostly from Loma Linda University of California, found and carefully documented 16,600 such remains of Theropods, a Dinosaur Group that includes Tyrannosaurus Rex. Their study, based on six years of regular field visits and published last Wednesday in the peer-reviewed journal plos One, reports that this finding represents the highest medical value recorded anywhere in the world.

“There is no place in the world where you have such a large bird’s beak (with that dobavu),” said Roberto Biaggi, the author of the meeting led by the Spanish Paleontologist RAúOntolopologist RAúlodologist RAúonvologist. “We have all these world records in this particular area.”

Print Record Dinosaur Behavior – including swimming attempts

The dinosaurs that ruled the world and roamed this region also made amazing attempts to swim here, according to the study, scratching there was a squishy lake depent to leave another 1,378 traces.

The longest swimming trackway studied by researchers measured more than 130 meters in length. “So far, it remains the world’s longest comfortable swimming pool,” the authors wrote in the study.

They pressed their claws into the mud just before the water levels rose and covered their tracks, protecting them for hundreds of years, scientists say.

“The preservation of most of the tracks is going well,” said Richard Butter, a paleontologist at the University of Birmingham who was not involved in the research. He said that, to his knowledge, the number of footprints and documents found in Toro Toro was unprecedented.

“This is an amazing window into the lives and behaviors of dinosaurs at the end of the Cretaceous,” Butler added, referring to the 66-year period that began when all the dinosaurs and 75% of living species died with them, according to scientists.

Footprints address conservation threats

Although they have survived for millions of years, human life is threatened by these monsters. For decades, farmers have threshed corn and wheat on the foothills. Workers nearby at Bounderby weren’t thinking too much about the formation as they blasted away at the limestone blocks. And two years ago, the researchers said, the emergence of Hiorway Clews workers through the hillsides almost wiped out a large site of dinosaur tracks before the intervention of the National Park.

Such disturbances may have something to do with the lack of space for dinosaur bones, teeth and eggs, experts say. In all Footprints Footprints and swimming were found across Tororo Toro Toro, There are almost no habitats of the kind that draw the peaks and valleys of patania and campanha in Brazil.

But osteoporosis can have environmental causes, too. This group said that the number and pattern of the tracks – and the fact that they were all found in the sediment layer – suggest that the dinosaurs did not settle in the ancient purvighay on the southwest coast and Argentina in the northwest.

Measurements of the size of the feet revealed that large creatures about 10 meters (33 feet) tall were transported in a thread with the size of a chicken-sized treat, 32 centimeters (1 foot) long at the waist.

When he presented a diagram of the daily behavior of the feet “it revealed what the bones were,” said Anthony Romilio, a paleontologist at the University of Queensland in Australia who was not involved in the study. From the footprints, researchers can tell when the dinosaurs walked or climbed, stopped or turned.

It is not clear why so many dinosaurs roamed the area

But the reason the Droves were transported to this immovable air platform remains a mystery.

“It is possible that they were all regular visitors to a large lake, of ancient water, of warm water, which often stretches along the muddy coast,” offered Romili.

Biaggi suggested that they are ‘running away from something or looking for a place to live.’

What is certain is that research on this ice treasure tracksite will continue.

“I suspect this will continue throughout the years and many more footprints will be found right there on the edge of what has been revealed,” said Biaggi.

The latest dinosaur footprint discovery

Researchers have found more dinosaur footprints recently.

In March, scientists in England discovered 650 feet of Dinosaur Footprints made 160 million years ago by Sauropod Dinosaurs.

In January, British researchers found others 200 Dinosaur Footprints Dating back 166 million years to what is believed to be the largest find in the United Kingdom. “This is one of the most impressive sites I’ve seen, on average, in terms of the size of the tracks,” Prof Kirsty Edgar, a micropaleontologist from BBMIngham, told BBC News. “You can go back in time and get an idea of ​​what it would have been like, these giant creatures just wandering around, going about their business.”

That discovery was announced just months after a team of paleontologists made the discovery to match the drawings of the dinosaur It is now two separate continents, separated by thousands of miles of ocean.

In October 2023, engineers in the UK did “Surprising Discovery” Of the dinosaur feet that experts believe could be mantellisaurus, a type of dinosaur that had three toes on each foot and walked on its hind legs.
