    Description: Placentals are the most abundant mammals that have diversified into every niche for vertebrates and dominated the world's terrestrial biotas in the Cenozoic. A critical event in mammalian history is the divergence of eutherians, the clade inclusive of all living placentals, from the metatherian-marsupial clade. Here we report the discovery of a new eutherian of 160 Myr from the Jurassic of China, which extends the first appearance of the eutherian-placental clade by about 35 Myr from the previous record, reducing and resolving a discrepancy between the previous fossil record and the molecular estimate for the placental-marsupial divergence. This mammal has scansorial forelimb features, and provides the ancestral condition for dental and other anatomical features of eutherians.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luo, Zhe-Xi -- Yuan, Chong-Xi -- Meng, Qing-Jin -- Ji, Qiang -- England -- Nature. 2011 Aug 24;476(7361):442-5. doi: 10.1038/nature10291.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Carnegie Museum of Natural History, Pittsburgh, Pennsylvania 15213, USA. luoz@carnegiemnh.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21866158" target="_blank"〉PubMed〈/a〉

    Description: A docodontan mammaliaform from the Middle Jurassic of China possesses swimming and burrowing skeletal adaptations and some dental features for aquatic feeding. It is the most primitive taxon in the mammalian lineage known to have fur and has a broad, flattened, partly scaly tail analogous to that of modern beavers. We infer that docodontans were semiaquatic, convergent to the modern platypus and many Cenozoic placentals. This fossil demonstrates that some mammaliaforms, or proximal relatives to modern mammals, developed diverse locomotory and feeding adaptations and were ecomorphologically different from the majority of generalized small terrestrial Mesozoic mammalian insectivores.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ji, Qiang -- Luo, Zhe-Xi -- Yuan, Chong-Xi -- Tabrum, Alan R -- New York, N.Y. -- Science. 2006 Feb 24;311(5764):1123-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Science, Nanjing University, Nanjing 200017, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16497926" target="_blank"〉PubMed〈/a〉

    Description: The definitive mammalian middle ear (DMME) is defined by the loss of embryonic Meckel's cartilage and disconnection of the middle ear from the mandible in adults. It is a major feature distinguishing living mammals from nonmammalian vertebrates. We report a Cretaceous trechnotherian mammal with an ossified Meckel's cartilage in the adult, showing that homoplastic evolution of the DMME occurred in derived therian mammals, besides the known cases of eutriconodonts. The mandible with ossified Meckel's cartilage appears to be paedomorphic. Reabsorption of embryonic Meckel's cartilage to disconnect the ear ossicles from the mandible is patterned by a network of genes and signaling pathways. This fossil suggests that developmental heterochrony and gene patterning are major mechanisms in homplastic evolution of the DMME.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ji, Qiang -- Luo, Zhe-Xi -- Zhang, Xingliao -- Yuan, Chong-Xi -- Xu, Li -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):278-81. doi: 10.1126/science.1178501.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19815774" target="_blank"〉PubMed〈/a〉

    Description: Multituberculates were successful herbivorous mammals and were more diverse and numerically abundant than any other mammal groups in Mesozoic ecosystems. The clade also developed diverse locomotor adaptations in the Cretaceous and Paleogene. We report a new fossil skeleton from the Late Jurassic of China that belongs to the basalmost multituberculate family. Dental features of this new Jurassic multituberculate show omnivorous adaptation, and its well-preserved skeleton sheds light on ancestral skeletal features of all multituberculates, especially the highly mobile joints of the ankle, crucial for later evolutionary success of multituberculates in the Cretaceous and Paleogene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yuan, Chong-Xi -- Ji, Qiang -- Meng, Qing-Jin -- Tabrum, Alan R -- Luo, Zhe-Xi -- New York, N.Y. -- Science. 2013 Aug 16;341(6147):779-83. doi: 10.1126/science.1237970.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Geology, Chinese Academy of Geological Sciences, Beijing, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23950536" target="_blank"〉PubMed〈/a〉
