Ancient relatives of modern toads were nail-sized and lived with dinosaurs 216 million years ago.
The fragments of bone size with eyelashes were found in the cliff, and experts believe that they are dating from late Triassic. The section of the femur, known as a bump, belongs to the group of amphibians, known as the Chinle frog, the branch of modern frog has long since died out.

Frog, a relative of modern amphibians, was found in a piece of rock and paleontologists say it dates back to 216 million years. It is believed that they were so small that they fit on the ends of the human finger (the impression of the artist is depicted)
Paleontologists from Viginia Tech have discovered fragments of fossils and claim they are the oldest known frogs in North America.
The fragments are packed in a rock and are smaller than nails, according to researchers.
The researchers found that the fragments are the first known and early equatorial remnants of salient – a group that contains live frogs.
is also believed to be the most closely associated with animals in the fossil record of modern frog.
The fossil origin comes from where they were found, the formation of Chinle Arizona.
Dr. Michel Stoke says that the scandal, discovered last May, highlights the importance of collecting microfossils. Professor of Geological Sciences at Virginia Tech, said: "This new find underscores how much you can still learn about the ecosystem of the late Triassic, and how much we find when we just look a bit closer.
Charismatic archosauers from Chinle's Formation, but we know, based on other ecosystems they should account for a small percentage of animals living together.
With this new focus, we can fill a lot of the lack of smaller components with new discoveries.
It is believed that the bones of the hips originate from several individuals and is up to angry and hollow.
Dr. Stocker added: "The Chinle Frog can fit at the end of a finger."
Despite the fact that the scapegoat is part of the seven toad Chinle, she said that they still do not call a specific scrum "
." We refrain from the name of this frog Chinlle, because we continue to handle the matrix of microverbs, which is likely to provide an additional skull and postcranial material that has the potential to be even more informative, "- added Dr. Stoker
. Toad also shares the similarity to Prosalirus and Triadobatrachus, from the early Jurassic and early Triassic, respectively.
Dr. Stocker said: "These are the oldest frogs near the equator."
"The oldest frogs are generally around 250 million years old from Madagascar and Poland, but these specimens are from higher latitudes and not equatorial. 19659024] A section of the femur, known as a bump, belongs to the group of amphibians known as the toad Chinle, a long-forgotten branch of modern frogs (pictured). The fossil part known as a blob bone belongs to the group of amphibians known as the toad Chinle – the branch of modern frogs has long extinct (pictured). The fossa of the femur, known as a blobbone, belongs to the group of amphibians known as the toad Chinle – the branch of modern frogs has long extinct (pictured). Dr. Stirling Nesbitt, also from Virginia Tech, said: "Now we know that tiny frogs were present about 215 million years ago from North America, we may be in a position
. ] He said that the new discovery is also the first time that the "fake" scum has been found directly with the early dinosaurs.
Student Rebecca Hawkins, who was part of the Research Group, said: "I learned firsthand about the hard work that the Paleontologists are investing in the search for scammers.
"Every day you will have to dare for long hikes, heavy loads, hot heat and much more.
Only with the right combination of patience and good fortune, you can find something really amazing, which makes it a laborious cost, like a tiny frog stem that tells a great story.
Ben Cleigman, a postgraduate student added: " Our developmental methods for extracting delicate bones from small bodily vertebrates
"Our goal is to use similar techniques in the formation of Chinle to discover the early history of other small animals, including lizards, salamanders, turtles and mammals."
The results have been published. online journal Biology Letters.
WHY DYNOZAVO REVEAL?
Dinosaurs ruled the Earth and dominated about 66 million years ago before they suddenly died out.
The appearance of the Cretaceous-Tertiary extinction is the name given to this mass extinction.
For many years, it was believed that climate change destroyed the food chain of huge reptiles. In the 1980s, paleontologists discovered a layer of iridium
This is an element that is rarely found on Earth but is in huge quantities in space.
When it was dated, it coincided exactly when the dinosaurs disappeared from the fossil. Ten years later, scientists discovered the massive Chiksulub crater on the top of the Yucatan peninsula of Mexico, which is related to this period.
A scientific consensus now says that these two factors are relevant, and both of them were probably caused by a huge asteroid that fell to Earth. caused seismic activity.
The fall would have led to the creation of a loop of ash, which probably covered the entire planet and made it impossible to survive the dinosaurs.
Other animals and plant species had a shorter period of time between generations, which allowed them to survive.
There are several other theories about what caused the death of famous animals.
One of the early theories was that small mammals ate dinosaur eggs, while the other believed that toxic poison seeds (flowering plants) destroyed them.
