Lambdopsalis bulla is an extinct multituberculate mammal from the Late Paleocene of China and Mongolia. It is placed within the suborder Cimolodonta and is a member of the superfamily Taeniolabidoidea. Fossil remains have been found in the Late Paleocene and in Nao-mugen and Bayn Ulan of China and Mongolia. 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.

  • Lambdopsalis bulla is an extinct multituberculate mammal from the Late Paleocene of China and Mongolia. It is placed within the suborder Cimolodonta and is a member of the superfamily Taeniolabidoidea. Fossil remains have been found in the Late Paleocene and in Nao-mugen and Bayn Ulan of China and Mongolia. Hair and fur fossilize very infrequently, if at all. This genus of burrowing multituberculate mammals provides one of the earliest unequivocal examples of mammal fur (Lower Cretaceous fossils of Eomaia, Volaticotherium and Castorocauda with the fur preserved still attached are currently the oldest). Indirect evidence suggest that hair first appeared on non-mammalian therapsids (Therapsida), back in the Triassic or even earlier. This is inferred from small hollows on the bone of the snout similar to holes in the skulls of cats which provide space for concentrations of nerves and blood vessels that innervate prominent whiskers (specialized hairs). This adaptation allows cats to use their whiskers as effective tactile sensory organs. 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. Studies on its tooth prism and enamel patterns have been performed. It had deciduous enamel, and there is evidence that adults and juveniles had substantially different diets. (en)
  • Lambdopsalis is een uitgestorven zoogdier uit de familie Lambdopsalidae van de Multituberculata. Dit dier leefde tijdens het Paleoceen in Azië. Er is één soort bekend, L. bulla. Fossielen van Lambdopsalis zijn gevonden in de Volksrepubliek China en dateren uit het Laat-Paleoceen. Het skelet van Lambdopsalis vertoont aanpassingen voor graven en het dier leefde vermoedelijk in holen. Goed bewaarde gebleven schedels wijzen er op dat het oor van Lambdopsalis ongeschikt was voor het horen van hoge frequenties vanuit de lucht, maar wel voor laagfrequente trillingen, geschikt voor een in holen levend dier. In fossiele coprolieten van roofdieren op dezelfde vindplaats is gefossileerd haar gevonden van Lambdopsalis, dat sterk overeenkomt met dat van hedendaagse zoogdieren. Dit is het enige directe bewijs dat multituberculaten behaard waren. (nl)

  • Lambdopsalis – rodzaj wymarłego ssaka z rodziny Taeniolabididae obejmujący pojedynczy gatunek L. bulla. Występował w dzisiejszych Chinach Azji w paleocenie. Pochodzi z warstwy ocenianej na górny paleocen w Nao-mugen and Bayn Ulan w Chinach. Etymologia: gr. λαμβδα lambda „jedenasta litera alfabetu greckiego (Λ)”; ψαλις psalis, ψαλιδος psalidos „para nożyc”. Ten przystosowany do rycia w glebie rodzaj dostarczył swego czasu najwcześniejszego dowodu na ssacze futro, jednak w 2002, jeszcze wcześniejsza, okazała się dolnokredowa Eomaia. Zbudowany z keratyny włos bardzo rzadko ulega fosylizacji. Prawdopodobnie pojawił się wiele wcześniej, u niebędących jeszcze ssakami terapsydów w triasie lub jeszcze wcześniej. Wniosek ten wyciągnięto na podstawie niewielkich zagłębień w kościach pyska, tworzących prawdopodobnie przestrzeń dla skupień naczyń krwionośnych i nerwów. Podobna cecha występuje u kota. Pozwala mu na używanie swych wibrysów jako narządu zmysłu. Jednakże pewne wyjątkowe chińskie skamieniałości zachowały ssacze futro i do nich właśnie zaliczają się pozostałości opisywanego rodzaju. Chodzi tu o koprolity zawierające niestrawione resztki pokarmowe. (pl)
