A New Haramiyid Indicating a Complex Pattern of Evolution in Mesozoic Mammals

摘要

Amajor unsolved problem in mammalian evolution is the origin of Allotheria,including Multituberculata and Haramiyida.Multituberculates are the most diverse and best known Mesozoic era mammals and ecologically resemble rodents,but haramiyids are known mainly from isolated teeth,hampering our search for their phylogenetic relationships.Researchers from the
