Talk:Peishansaurus

Which Peishan?

@Metaknowledge Here is my thinking at this time. 'Peishansaurus' is mentioned in the table of contents of Birger Bohlin's book on page 3 under the location heading 'Ehr-chia-wutung'. The map on page 4 of this pdf: [1] doesn't show Ehr-chia-wutung, but the English Wikipedia article mentions that the fossils were found at 'Ehr-chia-wu-t'ung'. The Hanyu Pinyin form of this is likely 'Erjiawudong'. I haven't found anything matching up with 'Erjiawudong' yet, but the map has a location labeled 'Ehr-chi-wu-l'ung'. The location of 'Ehr-chi-wu-l'ung' in the map is near to 甘肃北山 a name for a chain of mountains in the area which are pretty close to the modern-day border between Gansu and Xinjiang. If I could see page 67 of that book from 1953 it would probably make everything crystal clear, but the people who made the pdf only cared about the second part of the book. --Geographyinitiative (talk) 13:37, 23 October 2019 (UTC)

甘肃北山地区在中生代白垩纪时期自南向北分布着许多近东西向延伸的湖泊盆地，俞井子盆地为其中之一。 --Geographyinitiative (talk) 13:49, 23 October 2019 (UTC)

Contacted someone who may have access to the 1953 book [2] --Geographyinitiative (talk) 13:59, 23 October 2019 (UTC)

Not 100% sure, but this location seems to be what is today's Gansu [3] --Geographyinitiative (talk) 23:18, 23 October 2019 (UTC)

The answer should be related to this area: 馬鬃山 --Geographyinitiative (talk) 09:53, 24 October 2019 (UTC)

That town has about 3000 people and covers about 35000 km2 (larger than the land area of Taiwan) --Geographyinitiative (talk) 10:30, 24 October 2019 (UTC)

@Metaknowledge My preliminary conclusion is that this the mountain range of which Mt. Mazong 馬鬃山 (Mt. Horse Mane) is a part and which gives its name to the sparsely populated but large town of Mazongshan (in Subei Mongol Aut. County, Jiuquan, Gansu) is called 'Beishan' (the Northern Mountains), and it is the Wade-Giles romanized form which was used to name Peishansaurus. Let me know if you think there needs to be a closer analysis of the situation. I don't really know exactly how to add this information to Wiktionary, so I leave it in your hands. --Geographyinitiative (talk) 10:39, 24 October 2019 (UTC)

@Geographyinitiative: That seems to make sense. For Mazong, note also Equijubus. —Μετάknowledge^{discuss/deeds} 17:15, 24 October 2019 (UTC)

Khupatar-Peishan

Here's a period map that shows a Peishan in Xinjiang close to the border with Gansu. --Geographyinitiative (talk) 23:09, 24 October 2019 (UTC)

Comparing Google Maps and this map, I would say that the area where that mountain is on this map was originally in Xinjiang and is now in Gansu. --Geographyinitiative (talk) 23:14, 24 October 2019 (UTC)

Probably on here-->
