- Lambdopsalis
Taxobox name Lambdopsalis fossil range Paleocene regnum Animal ia phylum Chordata classis Mammal ia ordo Multituberculata subordo Cimolodonta superfamilia Taeniolabidoidea genus Lambdopsalis species L. bulla binomial Lambdopsalis bulla binomial authority Chow & Qi, 1978 Lambdopsalis is a genus of mammal from the Paleocene of China . This animal was a relatively large member of the extinct order Multituberculata . It is placed within the suborder Cimolodonta and is a member of the superfamily Taeniolabidoidea . The genus Lambdopsalis Chow M & Qi T, 1978 is known by the species Lambdopsalis bulla . Fossil remains have been found in Stratum strata dating to the Upper Paleocene in Nao mugen and Bayn Ulan of China. This genus of burrowing multituberculate mammals used to provide the earliest direct evidence of mammal fur. This is out of date since May 2002. The new record holder, Eomaia , comes from the Lower Cretaceous . Hair is highly unlikely to fossilize. There are indications that it 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, which may and probably did provide space for concentrations of nerve s and blood vessel s. It s a feature also known from cats. This adaptation allows cats to use their whiskers specialized hairs as effective sensory organs. However, some exceptional fossils from China do actually include mammal fur, some of which is from Lambdopsalis . These are coprolite s that contain the undigested leftovers excreted by carnivores.

- Maotherium
Taxobox name Maotherium fossil range Early Cretaceous regnum Animal ia phylum Chordata classis Mammal ia subclassis Theriiformes unranked superfamilia Trechnotheria superfamilia Spalacotherioidea genus Maotherium subdivision ranks Species subdivision M. sinensis M. asiaticus Maotherium was discovered in Early Cretaceous rocks in Liaoning Province, China , in 2003. Its scientific name means Mao s beast after the Chinese politician Mao Zedong . Maotherium belongs to an extinct group of Mesozoic mammal s called symmetrodont s. Though little is known about this group, the symmetrodonts have several similarities specifically their teeth. They have tall pointed, but simple molars in a triangular arrangement. Originally symmetrodonts were known since the 1920s. Now a vast majority have been restored, such as Zhangheotherium and Akidolestes , during the early 21st century. One of the fossils of Maotherium preserved the imprints of fur, like the mammals Eomaia and Sinodelphys . A species described in 2009, Maotherium asiaticus , sheds light on the Evolution of mammalian auditory ossicles evolution of the mammalian middle ear . In modern mammals, the Meckel s cartilage appears during Developmental biology development but disappears before adulthood. In Maotherium asiaticus , that cartilage not only remained, but turned into bone. ref name Ji et al 2009 Cite journal author Ji Qiang, Luo Zhe Xi, Zhang Xingliao, Yuan Chong Xi, Xu Li year 2009 title Evolutionary development of the middle ear in Mesozoic therian mammals journal Science pmid 19815774 volume 326 issue 5950 pages 278 281 doi 10.1126 science.1178501 url http www.sciencemag.org cgi content abstract 326 5950 278 ref This event in evolution may be an example of heterochrony , a change in the timing of development. ref name Martin & Ruf 2009 Cite journal author Martin, Thomas, & Ruf, Irina year 2009 title On the mammalian ear journal Science pmid 19815765 volume 326 issue 5950 pages 243 244 doi 10.1126 science.1181131 url ... more details
