†Arboroharamiya jenkinsiZheng et al., 2013 †Arboroharamiya allinhopsoni Han et al., 2017[1] Arboroharamiya is an extinct genus of early mammal (or possibly a non-mammalian mammaliaform) from the Middle Jurassic Tiaojishan Formation of Inner Mongolia, China.
[2] Arboroharamiya belongs to a clade or evolutionary grouping called Mammaliaformes, which includes mammals and their closest extinct relatives from the Triassic and Jurassic periods.
Some analyses place Haramiyida outside crown group Mammalia, meaning that they diverged from other mammaliaforms before the most recent common ancestor of living mammals appeared.
Other analyses place Haramiyida within Mammalia as part of an extinct group of Mesozoic mammals called Allotheria, which also includes Multituberculata.
Below is a cladogram or evolutionary tree from the analysis: Sinoconodon Adelobasileus Morganucodon Megazostrodon Haldanodon Castorocauda Hadrocodium Australosphenida (monotremes and extinct relatives) Fruitafossor Eutriconodonta Tinodon Haramiyavia Arboroharamiya Plagiaulacida Cimolodonta Symmetrodonta Dryolestes Henkelotherium Amphitherium Peramus Vincelestes Nanolestes Aegialodon Metatheria (marsupials and extinct relatives) Eutheria (placental mammals)
