Near the locality of the holotype specimen, here's the abstract:

A shame it is paywalled. Good they finally found another specimen work from though. Hopefully this helps clear some things up on the other specimens as well, and if there is in fact a second species or not.

yeah it is too bad. there is a nice picture of it though, but it has been turned into a meme.

I just had the chance to access the fine text of the paper thanks to free access granted by Taylor and Francis, and it should be noted that the paper referring LFKL-004 to Sinosaurus triassicus delineates two morphological differences between Sinosaurus sinensis from S. triassicus, and agress with Xu et al. (2021) in considering Shuangbaisaurus anlongbaoensis a distinct taxon from Sinosaurus (contra Currie et al. 2019, who synonymize Shuangbaisaurus with Sinosaurus), while noting that the lateral surface of IVPP V34 (holotype of Sinosaurus triassicus) and LFKL-004 both preserve a sharp ridge over the alveolar line.

V @VD231991 Thanks for the information and provided references. That clears up what I was wondering about earlier.

I wonder if this will spur PNSO to make a figure of Sinosaurus.
