The first dinosaur can be larger than expected

An ancient leg bone in Africa can provide a step forward to understand how dinosaurs and their close relatives were developed.

225 million -year -old Fusil has increased the growing evidence that a secret group of reigning animals known as Celassor played a more expected role during the Trusic period.

The neglect of the crawling animals suggests that the size of the first dinosaur can be considered less.

In 1963, a team of British scientists now revealed a prehistoric leg bone in Zambia. Although it was not known at that time, Jovashim Famil was one of the first Silasor bones found to be known as science.

The correct identity of Silesore is under discussion, but it is believed that they are either a dinosaur or a close relative of dinosaurs. This means that ancient reptile animals can be used to present new indicators about the ancestors of the dinosaur.

Jack Lugroo, a PhD. A student who led a new research on Zambian Famil says it provides additional evidence that shows that the initial dinosaur may be less than starting over time, rather than before.

“Some pieces of cyllysis and a group of early dinosaurs suggest that these animals may be far larger than more complete remnants,” says Lugreo. “Since the larger animals are found near the beginning of the dinosaur, it increases the possibility that the first dinosaur was bigger than our forecast.”

“If this is the case, then some dinosaur groups would have been really smaller in the trash. Finding more Silasor fossils can help us know how they belong to the initial dinosaur and confirm the existence of these size trends.”

The results of this study were published in the Journal Royal Society Open Science.

What are the slices?

Slasore is a group of dinosaurs -like crawling animals that lived 240 to 200 million years ago. Despite the ancient age of these animals, they were only recognized as a separate group in 2010.

The most famous species is the slices, which gives its name to the big group. The animal was about two meters long and had a lime jaw, which allowed it to eat insects or plants.

At the time of his discovery, Silesore was initially considered a sister group for dinosaurs. But subsequent research suggests that Silisor is actually early dinosaurs. Their lower jaw teeth have been used as proof of the tip to connect them to Aurithechens, which is a large dinosaur group, which later included animals like Stagusorus and Traystertps.

This debate has been difficult to resolve because the remains of these animals are usually so difficult to keep on pieces and family trees. Scientists are now suffering from new gambling to improve their understanding of these animals.

In addition to searching for new discoveries in this field, researchers are also looking at fossils in museums. Before realizing its importance in the 2010s, the leg bone was kept in the Natural History Museum for more than 50 years.

“It was now discovered in the early 1960s on a campaign between Zambia and Tanzania in the early 1960s,” said Lugreo. “Researchers were primarily interested in studying stretching animals such as dyshonodonts and syndronts, but it also found a variety of fossils.”

“Since the focus was not on which he was focusing on, it was not studied until one of my co -authors, Brandon, came to him.

A step change for slicesuroids

Zambia’s trays are rich in the remains of the stone Silasore. To date, the only name of the country is the Lutingotali set Wesis, but dozens of different unknown cellsor foes have also been discovered.

Many of them are about 15 centimeters in length, but more than double the steps. Different sizes of the leg of the leg can represent lyting in different ages or multiple species that live together.

Although this study cannot ultimately rule on one or the other, the samples of the natural history museum care bone are different from other patterns discovered in the same region. This indicates that a variety of slysur species were living at the same time, but scientists would need more fossils before they named them with confidence.

“It is historically believed that in the past there was only one slysuride in the area.” “As a result, the focus of different species has been combined with each other.”

“This can explain us to this uncertainty when we try to understand how slicesorides belong to other animals. New datases will be important to end these evolutionary relationships and act really what is happening.”

The presence of a large silicaver in the region changes our understanding of the ecosystem during the trays. Although these animals were considered a small part of the Dysneodont majority scenes, it is possible that Sysorodis had in fact ruled the roast.

“The bone we have studied, as well as other people, suggest that perhaps the Celeceroids are the largest herbs in some parts of the world at this point of the trays.” “The biggest silicaroids were probably taller and taller than Desinodonts, even if they were light.”

“This shows that they have felt more than that they have probably had a much more effect on the ecosystem, especially since they are the most common archosis found in the region.”

Although slicesuroids are well considered well for now, our knowledge of these crawling animals is spreading rapidly. Since experts dig a deep into these animals, they come close to setting the beginning of silicaroids and dinosaurs for all and all.
