Y. hepingensis[edit]

Image:Yangchuanosauru.jpg says the image shows Y. hepingensis (perhaps from a place called Heping?), but that species is not mentioned in this article. Wikipeditor 03:42, 27 November 2006 (UTC)[reply]

Heping is a township within the prefecture-level city of Zigong. I'm adding a photo of the skull of Y. Hepingensis with the associated translation of the card below it. I've got a picture also of the english version of the card from the opposite side of the case - but the view of the skill is not as nice from that angle. The translation explains Y. Hepingensis origins and classification - according to the museum. I also have a photo which explains the localities of the dinosaur finds in Zigong.Phreakster 1998 02:59, 28 November 2006 (UTC)[reply]

I had added the information to this page - but Dinoguy(sp?) believed it was misclassified by the Chinese and is actually a sinraptor instead of a Yangchuanosaurus. However, the museum beleives that it is. I'm not an expert. Phreakster 1998 04:11, 28 November 2006 (UTC)[reply]

Thank you. Wikipeditor 06:08, 28 November 2006 (UTC)[reply]

It seems Dragon Helm also thinks it's a "sinraptor". Wikipeditor 07:24, 28 November 2006 (UTC)[reply]

I'm a bit confused. Is there any references as to the misclassification and why the museum, several guidebooks, and photographs continually reference this skeleten as Y. Hepingenis? Phreakster 1998 14:42, 28 November 2006 (UTC)[reply]

Nevemind - looks like it was originally misnamed in 1992 Phreakster 1998 14:42, 28 November 2006 (UTC)[reply]

yangchuanossaurus in portuguese[edit]

Yangchuanossauro cujo nome significa "réptil de Yang-chuan foi uma espécie de dinossauro carnívoro e bípede que viveu há aproximadamente 180 milhões de anos e viveu No periodo jurrassico ate o cretaceo e .viveu em torno de 163-145 milhoes de anos atras Media 11metros de comprimento, 4,5 metros de altura e pesava 3,5 toneladas. Sua classe era teropode Foi um dos grandes carnívoros de seu tempo, era mais rápido que a maioria dos outros com o seu tamanho, sua cabeça lhe permitia ferir a presa durante a perseguição e era muito forte e suas patas dianteiras não eram tão pequenas como as de outros terópodes, permitindo utilizá-las em suas caçadas , coisas que faziam desse dinossauro um dos mais temidos do período Jurássico Nome Científico: Yangchuanosaurus shangyouensis

Reino:                                    animál

Filo: chordata Superordem: dinossaria Ordem: salrischia Subordem: theropoda Infra-ordem: ceratossauria Família: megalosauridae

                  Vertebrado

Yangchuanosauro foi encontrado na, China (Szechuan, ) em1970. Está na exposição no museu do historia natural de Beijing. Yangchuanosauro foi nomeado por Dong Zhiming em 1978 ele era da mesma família que o carnotauro mas cuja inteligência (medida por seu peso de corpo relativo do EQ) fosse elevado entre os dinossauros. sua DIETA : ele era um comedor da carne. Era um predador grande, feroz que poderia matar mesmo sauropods grande ele pode também ter sido um limpador. Sua locomocao era de andar em dois pés musculares e foi um corredor relativamente rápido. As velocidades do dinossauros são estimadas usando sua morfologia (características como o comprimento do pé e a massa estimada do corpo) e trackways fossilizados

Era um carnívoro grande, ereto, feroz que vivesse rapinado em outros dinossauros. O Yangchuanosauros teve: dagger, dentes curvados pra ajudar a agarrar a presa; seis furos grandes na sua caveira pra ajudar reduzir seu peso para a mobilidade melhor; olhos para diante-(revestimentos que lhe deram a percepção de profundidade boa); uma cauda longa pra ajudar balançar seu corpo ao funcionar. —The preceding unsigned comment was added by 201.34.236.198 (talk) 14:06, 27 April 2007 (UTC).[reply]

Age[edit]

There's a bunch of confusion with the dates in this article. The Bathonian and Callovian stages are both middle Jurassic, not late, and they don't align with the "161.2-154 million years ago" date. The referenced paper in which the genus is first described is actually from 1975, not 1978, and the name is already being used, so a bunch of the dates about the discovery are also off. https://paleoglot.org/files/Dong&%201975.pdf In this paper Dong says he thinks the fossils are late Jurassic, not middle. 42.111.138.26 (talk) 13:31, 27 July 2018 (UTC)[reply]
