Scientists have discovered a new dinosaur species: it is the oldest carnivorous dinosaur found in Britain

this small carnivorous dinosaur lived more than 200 million years ago (now Wales). Dinosaur fossils were found in a quarry in the 1950s. It was initially considered to belong to a completely different dinosaur group, but scientists have now realized that it represents a new species: pendraig milnerae

its name is not only to commemorate its Welsh origin, but also to commemorate the paleontologist Angela Milner of the museum. She is the promoter of the dinosaur exhibition hall of the museum and has named various new species herself

Angela has been a leader in this field for decades. This naming also reflects Angela’s help in repositioning dinosaurs many years after they disappeared in the museum

Dr. Susannah Maidment, a senior researcher in Museum paleontology who studied under Angela, said: “I told her I couldn’t find it, so she left, and she found it about three hours later.” “She found it in the crocodile material in a drawer. She must have left the specimen in her mind when looking through the specimen before. Without her, this paper would not have been published.”

this new species has been published in open science of the Royal Society Described in the journal.

this new species has some mysterious past. In the past 40 years, it has been lost, discovered and renamed. It was originally found in pant-y-ffynnon in southern Wales, in a sediment called crack filler. This is where the remains fell into cracks before they were covered and fossilized.

these cracks have been filled for many years Fillings provide a variety of fossils dating back to the Triassic period, allowing researchers to see the early evolutionary history of mammals, crocodiles and dinosaurs.

in 1952, researchers found some dinosaur bones in one of the cracks, including parts of the back, legs and hips. Although this may have no basis, researchers can identify that the animal may be A coelophysoid. This is a small carnivorous dinosaur with a long and narrow nose, which is common in the Late Triassic and early Jurassic.

this species is the oldest theropod found in the UK, representing a major leap in the understanding of the early evolution of dinosaurs in Europe.

Dr. Stephan spiekman, researcher of the museum and lead author of the paper “There are no obvious features that make this species different. It has some combination of several features that are unique in its population, which shows us that it is obviously a new species,” he said

it is believed that the smaller size of P. milnerae may be due to the bone from a dinosaur cub. The adult animal may be larger than the specimen found in Wales, but this cannot be confirmed due to the process of fossilization.

is considered due to its hypothetical habitat It is an island archipelago, which makes the situation more complicated. Species living on islands usually become smaller because of the reduction of resources available to them and the lack of large predators. This shrinkage is a process called Island dwarfing. Because of this, there has been a lot of uncertainty about the exact identity of dinosaurs.

fossils of young animals are usually not shown All the unique features that help to distinguish one species from another. In the case of this dinosaur, this has caused a lot of confusion over the years. Scientists in the 1990s initially described it as a species of syntarsus.

however, the name quickly changed after scientists thought that syntarsus species was actually related to other groups and redistributed it They were abandoned, so further research was needed.

however, when scientists looked for these remains after these changes for re evaluation, they were not where the researchers thought they were. Finding the remains needed the help of paleontologists and Museum veterans, so the researchers turned to Dr. Angela Milner.

Angela has been in her position for 40 years She is an influential figure in paleontology. She is an expert in quadrupeds, including mammals, reptiles and amphibians.

in 1976, she joined the museum as curator and began to expand her research on a series of dinosaurs. In 1983, she and Other paleontologists Alan charig formally described the newly discovered baryonyx walkeri, a large carnivorous dinosaur.

in addition to the new research she led, Angela’s years in the museum gave her a deep understanding of how to best educate the public about dinosaurs. She played a role in developing the dinosaur exhibition hall of the museum, displaying many iconic species, including a dinosaur Some of the species she participated in naming. Angela’s work in so many areas of the museum is encouraging for those who work with her.

Susannah said: “Angela has been really important to the museum for many years. She is not only a leading dinosaur researcher, but also holds senior positions. At that time, women did not have these positions in the museum, so it is really important for me as a student. When I joined the museum, she really inspired me and helped me a lot. She spared no effort to show me Point maze, which is true for me and many others, including the three in our paper. ”

researchers now hope to have a deeper understanding of P. milnerae’s life and the fauna it lives in, so as to prove whether its size is the result of living on the island
