Meet T.Rex's ancestor! Dinosaur roamed Wales 215 백만년 전

Meet T.Rex’s Welsh ancestor! Bizarre chicken-sized dinosaur dubbed the ‘Chief Dragonroamed southern Wales 215 백만년 전, 화석 분석 결과

  • Scientists discovered the fossil in a quarry in Pant-y-ffynnon, southern Wales
  • Initial analysis suggests the dinosaur was chicken-size with a long tail
  • The dinosaur is a theropod – a group which also includes T.Rex – and lived between 200 과 215 백만년 전
  • T.Rex is often described as the ‘King of the Dinosaurs’, thanks to its ferocious appetite and ruthless killing tactics when it roamed the Earth 80 백만년 전.

    But a new study suggests that one of T.Rex’s ancient ancestors may not have been quite so scary, and was actually just the size of a chicken.

    Researchers from the Natural History Museum and the University of 버밍엄 discovered the remains of the creature in a quarry in Pant-y-ffynnon in southern Wales.

    The dinosaur, dubbed Pendraig milnerae, is a theropod – a group which also includes T.Rex – and lived between 200 과 215 백만년 전.

    Richard Butler, 연구의 공동 저자, 말했다: ‘Dinosaur discoveries are really rare in Wales, and this is only the third dinosaur species known from the country.

    ‘It’s very exciting to learn more about the dinosaurs that lived here in the UK during the Triassic, right at the dawn of dinosaur evolution.

    Meet T.Rex’s Welsh ancestor

    The team named the species Pendraig milnerae.

    Pendraig means ‘Chief Dragonin Middle Welsh, while milnerae honours Dr Angela Milner, who was instrumental in locating the specimen, but sadly passed away in August 2021.

    An initial analysis indicates that the dinosaur likely had a body size around that of a modern-day chicken, but boasted an impressive tail that took its total length to 3.2ft (one metre).

    The team discovered several fragmented fossils while exploring the quarry, including its articulated pelvic girdle, sacrum and posterior dorsal vertebrae, and an associated left femur.

    An initial analysis indicates that the dinosaur likely had a body size around that of a modern-day chicken, but boasted an impressive tail that took its total length to 3.2ft (one metre).

    Dr Stephan Spiekman, first author of the study, 말했다: ‘Pendraig milnerae lived near the beginning of the evolution of the meat-eating dinosaurs.

    ‘It’s clear from the bones we have that it was a meat-eater, but early in the evolution of this group these animals were quite small, in contrast to the very famous meat-eating dinosaurs like T. rex which evolved much later.

    The team named the species Pendraig milnerae. Pendraig means ‘Chief Dragonin Middle Welsh, while milnerae honours Dr Angela Milner, who was instrumental in locating the specimen, but sadly passed away in August 2021.

    ‘I told Angela that I couldn’t find the specimen, and so she went away and about three hours later she had it,’ said Dr Susannah Maidment, a Senior Researcher in paleobiology at the Natural History Museum.

    ‘She found it in a drawer with crocodile material. She must have had the specimen in her mind’s eye from when she had previously looked through that drawer. This paper would not have been possible without her.

    The new dinosaur’s diminutive size also hints at possible ‘island dwarfismin the area, 연구원에 따르면.

    Dr Spiekman explained: ‘The area where these specimens were found was most likely an island during the time period in which it lived.

    ‘Species which live on islands often tend to become smaller than those on the mainland in a phenomenon called island dwarfism.

    ‘Because the fossil reptiles from this area, including Pendraig, are all quite small-sized, we used statistical analyses to investigate whether Pendraig might have been an insular dwarf.

    ‘The results indicate that Pendraig is indeed small, even for a theropod of that time period, but not uniquely so.

    '더욱이, based on several characters on the bones, we were able to determine that, although the specimens of Pendraig were not very young, they were also likely not fully grown.








    ‘So Pendraig might have gotten somewhat bigger than the specimens we have so far, which limits our ability to perform reliable body size analyses.

    ‘With this in mind, we need more evidence from more species to investigate the potential for island dwarfism in this area during that time, but if we could prove it, it would be the earliest known occurrence of this evolutionary phenomenon.

    공룡이 멸종 한 방법 66 백만년 전

    공룡은 지구를 지배하고 지배했습니다. 66 백만년 전, 갑자기 멸종되기 전에.

    백악기-제 3 기 멸종 사건은이 대량 멸종에 주어진 이름입니다.

    변화하는 기후가 거대한 파충류의 먹이 사슬을 파괴했다고 수년 동안 믿어졌습니다..

    1980 년대, 고생물학 자들은 이리듐 층을 발견했습니다.

    이것은 지구상에서는 드물지만 우주에서 방대한 양으로 발견되는 원소입니다.

    이것이 날짜가되었을 때, 공룡이 화석 기록에서 사라 졌을 때와 정확히 일치했습니다..

    10 년 후, 과학자들이 멕시코 유카탄 반도 끝에있는 거대한 Chicxulub 분화구를 발견했습니다., 해당 기간의 날짜.

    과학적 합의에 따르면이 두 가지 요소는 서로 연결되어 있으며 둘 다 지구에 충돌하는 거대한 소행성 때문일 것입니다..

    예상 크기 및 충격 속도, 충돌은 엄청난 충격파를 일으키고 지진 활동을 촉발 시켰을 것입니다..

    낙진은 지구 전체를 덮을 수있는 화산재 기둥을 만들어 공룡이 생존하는 것을 불가능하게 만들었을 것입니다..

    다른 동물과 식물 종은 세대간에 더 짧은 기간을 가졌기 때문에 생존 할 수있었습니다.

    유명한 동물의 죽음의 원인에 대한 몇 가지 다른 이론이 있습니다..

    하나의 초기 이론은 작은 포유류가 공룡 알을 먹었고 다른 하나는 독성 혈관 식물이 (꽃 피는 식물) 그들을 죽였다.
