Euharamiyida

Euharamiyida is an extinct clade of Mesozoic mammaliaforms that includes haramiyidans known from fossils in Asia, Europe, and Africa. Its members are known chiefly from distinctive teeth and, in some cases, exceptionally preserved skeletons.

Mammaliaformes: Mammaliaformes are mammals and their closest extinct relatives, including forms on the lineage leading to living mammals. Euharamiyida is placed within this broader group of mammal relatives.
Arboroharamiya: Arboroharamiya is a Jurassic mammaliaform genus known from fossils in China. Its articulated fossils provide unusually direct evidence about euharamiyidan anatomy.
Mammalian tooth: A mammalian tooth is a mineralized structure specialized for biting, cutting, or grinding food. Euharamiyidan identification and much of their functional interpretation depend on teeth.
Mammal evolution: Mammal evolution is the history of mammalian lineages from their synapsid ancestors to living diversity. The placement of Euharamiyida affects reconstructions of early mammal diversification.
Haramiyida: Haramiyida is a Mesozoic group of mammaliaforms known especially for complex cheek teeth. The name and taxonomic scope of Euharamiyida are tied to the wider haramiyidan grouping.
Megaconus: Megaconus is a Jurassic mammaliaform genus from China, represented by a remarkably complete skeleton. Its preserved skeleton helped establish the body form of a euharamiyidan.
Tooth occlusion: Tooth occlusion is the contact between opposing teeth during jaw closure. Wear and cusp relationships help infer how euharamiyidan cheek teeth processed food.
Allotheria: Allotheria is a proposed grouping of extinct mammaliaforms that includes multituberculates and haramiyidans in some classifications. Some analyses place euharamiyidans within or near this contested assemblage.
Mammalia: Mammalia is the crown group containing the last common ancestor of living mammals and all its descendants. Euharamiyidans are mammaliaforms, but their position relative to crown Mammalia remains debated.
Vilevolodon: Vilevolodon is a Jurassic mammaliaform from China with adaptations for gliding. Its fossils connect euharamiyidans with an unusual locomotor adaptation.
