A recent paper I somehow missed posting from back in August:

Five multituberculate species have been reported to date from the upper
Lower Cretaceous (Aptian–Albian) Shahai and Fuxin formations in Liaoning
Province, northeastern China. We herein describe an additional species of
eobaatarid multituberculate from the Fuxin Formation, Dolichoprion lii,
gen. et sp. nov., with a long (relative to height) crown of the fourth
lower premolar, which is unique among eobaatarids. We also describe the
upper dentition possibly referable to another eobaatarid genus previously
known only from lower jaws, Liaobaatar, based on a newly discovered
specimen. The new species is the sixth multituberculate (and the fourth
eobaatarid) species described from the Shahai and Fuxin formations. These
species suggest that multituberculates, especially eobaatarids, were
taxonomically quite diverse in the mammalian fauna of East Asia at that
time.
