This fossil find -- the oldest ancestor in the multituberculate family tree -- represents a newly discovered species known as Rugosodon eurasiaticus.
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.
That ultimately led to multituberculate extinction about 34 million years ago.
The scientists examined teeth from 41 multituberculate species kept in fossil collections worldwide.
INTRODUCTION The study of the Multituberculate, Ectypodus lovei, is part of a larger analysis of the small mammal fauna from the Medicine Pole Hills Local Fauna.
DISCUSSION All of the identifiable multituberculates that have been reported from post-Bridgerian rocks have been assigned to Ectypodus and nothing in our sample suggests a different genus.
While Krause and his colleagues must content themselves with a fistful of teeth from Madagascar, the Gobi Desert in Mongolia has provided scientists with a veritable treasure trove of multituberculate
Jaw movement, dental function, and diet in the Paleocene multituberculate
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).
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.
