Liaoningotitan is from the Jianshangou Bed of the Yixian Formation, near Xiaobeigoucun, Beipiao City.
Gazing at the pdf for a minute until I recognized a character other than "bone", I found this in section 0, right under "2007":
在辽西北票小北沟
"in western Liáoníng, Běipiào, Xiǎoběi-", and then Google Translate says 沟 is gōu and forms parts of words with ditch-related meanings, so it's probably the "valley" term that is so common in placenames. Google Translate further confirms that "village" is cūn 村; it's not surprising that the "village" part of "Little North Valley Village" is left off in the usual general-to-specific succession of placenames. In short, I think Liaoningotitan is indeed from the same area as Yutyrannus.
Also, the species name is spelled sinensis in the main text, the Chinese abstract and all figure & table legends, so the "sinesis" in the English abstract can be safely ignored as a typo.
