Lambdopsalis bulla is an extinct multituberculate mammal from the Late Paleocene of China. It is placed within the suborder Cimolodonta and is a member of the superfamily Taeniolabidoidea. Fossil remains have been found in Upper Paleocene strata in Nao-mugen and Bayn Ulan of China. In the same Upper Paleocene strata, exceptionally preserved coprolites, originally excreted by unknown carnivorous animals, were discovered to contain undigested remains, including hair from Lambdopsalis and three other different mammal taxa.
