Eobaataridae
Eobaataridae is a family of fossil mammals within the order Multituberculata. Remains are known from the Lower Cretaceous of Europe and Asia. They are among the most derived representatives of the informal suborder "Plagiaulacida", and closely related to Cimolodonta. Most eobaatarids are only known from isolated teeth, though several reasonably complete members are known, including '' Sinobaatar'' and ''Jeholbaatar''. The body of ''Sinobaatar'' is generalised, while ''Jeholbaatar'' displays clear adaptations for scansoriality (climbing) due to its elongated digits. Due to the morphology of the cheek teeth, ''Eobaatar'' and ''Jeholbaatar'' are inferred to be omnivorous, likely feeding on plants and invertebrates. ''Indobaatar'' from the Early Jurassic Kota Formation has been suggested to be the earliest known multituberculate, let alone the earliest eobaatarid, and may stretch the eobaatarid-cimolodontan group much earlier than previously thought. However its referral to the family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plagiaulacida
Plagiaulacida is a group of extinct multituberculate mammals. Multituberculates were among the most common mammals of the Mesozoic, "the age of the dinosaurs". Plagiaulacids are a paraphyletic grouping, containing all multituberculates that lie outside of the advanced group Cimolodonta. They ranged from the Middle Jurassic Period to the early Late Cretaceous of the northern hemisphere. During the Cenomanian, they were replaced by the more advanced cimolodontans. Kielan-Jaworowska and Hurum (2001) divides “Plagiaulacida” into three informal lineages, the paulchoffatiids, the plagiaulicids, and the allodontids. Allodontid line The Allodontid line may be a superfamily, Allodontoidea. Both allodontids and paulchoffatiids (below) were among the most basal of the plagiaulacids. The Allodontid line contains: The family Allodontidae is known from two genera from the Upper Jurassic Morrison Formation of North America. The family Zofiabaataridae contains a single genus, '' Zofia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eobaataridae is a family of fossil mammals within the order Multituberculata. Remains are known from the Lower Cretaceous of Europe and Asia.

Heishanobaatar
''Heishanobaatar'' ("Heishan hero" from Chinese 黑山 (Hēishān), " Heishan" + Mongolian baatar, "hero") is an extinct genus of eobaatarid multituberculate which existed in Shahai and Fuxin formations, northeastern China, during the early Cretaceous ( Aptian/Albian The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/ Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0 ... age). It was first named by Nao Kusuhashi, Yaoming Hu, Yuanqing Wang, Takeshi Setoguchi and Hiroshige Marsuoka in 2010 and the type species is ''Heishanobaatar triangulus''. Known from dentaries, lower incisors, and premolars, ''Heishanobaatar'' is distinguished by its laterally triangular third premolar, from which its species name is derived. Its referral to Eobaataridae was considered questionable by Kusuhashi et al. 2019. References Cretaceous mammals Mul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multituberculata
Multituberculata (commonly known as multituberculates, named for the multiple tubercles of their teeth) is an extinct order of rodent-like mammals with a fossil record spanning over 130 million years. They first appeared in the Middle Jurassic, and reached a peak diversity during the Late Cretaceous and Paleocene. They eventually declined from the mid Paleocene onwards, disappearing from the known fossil record in the late Eocene. They are the most diverse order of Mesozoic mammals with more than 200 species known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism to jerboa-like hoppers. Multituberculates are usually placed as crown mammals outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and MonotremataAgustí-Antón 2002, pp 3-4—but usually as closer to Theria than to monotremes. They are considered to be clo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monobaatar
''Monobaatar'' is a genus of extinct mammal from the Lower Cretaceous of Mongolia. It was within the also extinct order Multituberculata, and lived during the "age of the dinosaurs". It is also within the suborder "Plagiaulacida" and has been tentatively referred to the family Eobaataridae, though it probably is not a member. The genus ''Monobaatar'' (Kielan-Jaworowska, Dashzeveg & Trofimov, 1987) is known from the species ''Monobaatar mimicus'', which itself is very poorly known. Fossil A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved ... remains come from the Lower Cretaceous of Mongolia.

Loxaulax
''Loxaulax'' ("slanting groove" from Ancient Greek λοξός (loxós), “slanting, crosswise” + αὖλαξ (aûlax), "furrow, groove") is a genus of extinct mammal from the Lower Cretaceous of southern England. It was a member of the also extinct order Multituberculata, and lived alongside the dinosaurs. It lies within the suborder "Plagiaulacida" and family Eobaataridae. The genus ''Loxaulax'' was named by Simpson G.G. in 1928 based on one species. Fossil remains of the species ''Loxaulax valdensis'' consist of a tooth found in Valanginian (Lower Cretaceous) strata belong to the Wadhurst Clay Formation of the Cliff End bonebed in Hastings, England. More recently, "Butler and Ford reported some IoW (Isle of Wight) Wealden mammal teeth several decades ago from the Wessex Formation. They identified one of the teeth as belonging to the multituberculate ''Loxaulax'' but weren't sure about the others. Other IoW Wealden mammal teeth have been found since but have yet to be writt ...

Eobaatar
''Eobaatar'' is a genus of extinct mammal from the Lower Cretaceous of Mongolia, Spain and England. A member of the also extinct order Multituberculata, it lies within the suborder Plagiaulacida and family Eobaataridae. The genus ''Eobaatar'' was named by Kielan-Jaworowska Z., Dashzeveg D. and Trofimov B.A. in 1987. Its name was made from Greek "eos" = "dawn" and Mongolian "baatar" = "hero"", "warrior".
