A Systematic Study on Tooth Enamel Microstructures of Lambdopsalis bulla (Multituberculate, Mammalia) - Implications for Multituberculate Biology and Phylogeny
Tooth enamel microstructure is a reliable and widely used indicator of dietary interpretations and data for phylogenetic reconstruction, if all levels of variability are investigated. It is usually difficult to have a thorough examination at all levels of enamel structures for any mammals, especially for the early mammals, which are commonly represented by sparse specimens. Because of the rando...
متن کاملLargest known Mesozoic multituberculate from Eurasia and implications for multituberculate evolution and biology
A new multituberculate, Yubaartar zhongyuanensis gen. and sp. nov., is reported from the Upper Cretaceous of Luanchuan County, Henan Province, China. The holotype of the new taxon is a partial skeleton with nearly complete cranium and associated lower jaws with in situ dentitions. The new species is the southern-most record of a Late Cretaceous multituberculate from outside of the Mongolian Pla...
متن کاملThe Earliest Mammal of the European Paleocene: the Multituberculate Hainina
A new species of multituberculate mammal, Hainina pyrenaica n. sp. is described from Fontllonga-3 (Tremp Basin, Southern Pyrenees, Spain), correlated to the later part of chron C29r just above the K/T boundary. This taxon represents the earliest European Tertiary mammal recovered so far, and is related to other Hainina species from the European Paleocene. A revision of the species of Hainina al...
متن کاملEnamel microstructure of the Late Cretaceous multituberculate mammal Kogaionon
Cretaceous multituberculate mammals of Europe are poorly known, as a rule represented by isolated teeth. The only exception is the Late Cretaceous (Maastrichtian) monotypic genus Kogaionon Riidulescu & Samson, 1996 from Romania, represented by a single skull, without dentaries, assigned to Kogaionidae Rhdulescu & Samson, 1996, Another kogaionid genus is Hainina Vianey-Liaud, 1979, represented b...
متن کاملA new taeniolabidoid multituberculate (Mammalia) from the middle Puercan of the Nacimiento Formation, New Mexico, and a revision of taeniolabidoid systematics and phylogeny
Multituberculates were amongst the most abundant and taxonomically diverse mammals of the late Mesozoic and the Paleocene, reaching their zenith in diversity and body size in the Paleocene. Taeniolabidoidea, the topic of this paper, includes the largest known multituberculates, which possess highly complex cheek teeth adapted for herbivory. A new specimen from the early Paleocene (middle Puerca...
