Aquila Bullockensis
''Aquila bullockensis'' is an extinct species of large true eagles in the family Accipitridae. ''A. bullockensis'' is related to the living species '' A. audax'' to which it might be ancestral. The species is solely known from the distal end of a right humerus found in the Middle Miocene (about 12 Ma), Bullock Creek deposits in Australia. ''A. bullockensis'' is the oldest confirmed record of the genus '' Aquila'' in Australia, and possibly in the world. History and classification The species is known solely from the holotype specimen, number QVM:2000:GFV:154, the distal end of a right humerus, conserved in the collections housed by the Queen Victoria Museum and Art Gallery in Launceston, Tasmania. The specimen was collected from Bullock Creek exposures of the Camfield Fossil Beds, located south-southeast of Darwin, Northern Territory, Australia. The bone was first studied by a pair of researchers from Monash University in Melbourne, Victoria Melbourne ( ; Boonwurr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene Climate Transition. For the purpose of establishing European Land Mammal Ages The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of Europe ... this sub-epoch is equivalent to the Astaracian age.
