Cuenca-Bescos, A Systematic Reassessment of Early Cretaceous Multituberculates
from Galve (Teruel, Spain), Cretaceous Res.
The Lainodontinae (Zhelestidae) is the most diverse and dominant taxon in the Late Cretaceous mammalian faunas of Western Europe, by contrast to Central European sites that include only kogaionid multituberculates
(Kielan-Jaworowska et al.
TEHRAN (FNA)- The 160 million-year-old fossil of an extinct rodent-like creature from China is helping to explain how multituberculates
-- the most evolutionarily successful and long-lived mammalian lineage in the fossil record -- achieved their dominance.
London, March 15 ( ANI ): Scientists have revealed that rodent-like creatures called multituberculates
, flourished during the last 20 million years of the dinosaurs' reign and survived their extinction 66 million years ago.

are an extinct lineage of mammal, which had their first appearance in the Jurassic, are common in the early Tertiary and become extinct in the middle Chadronian (4).
Mammal phylogeny - Mesozoic differentiation, multituberculates
, monotremes, early therians and marsupials.
Chief among these early mammals was an order called the multituberculates
, a tongue-twisting name that paleontologists often shorten to multis.
Tubules have been noted in a wide variety of taxa, occurring extensively in marsupials and multituberculates
and to a lesser degree in bats, primates, and rodents (Sahni, 1985).
These fossils have increased the resolution of European Early Cretaceous multituberculate
mammalian biodiversity, biostratigraphy and palaeobiogeography: (1) The discovery of a new late Hauterivian-early Barremian pinheirodontid taxon demonstrates greater biodiversity and a wider biostratigraphic distribution for these multituberculates
than was previously known.
The mammals are most likely multituberculates
, an extinct order of archaic mammals that resemble rodents and had paired upper and lower incisors - which they used to gnaw at the bones for minerals rather than for meat.
