In the jump of 2017, Dr Yuri Kimura, from the Department of Geology in addition to Paleontology at the National Museum of Nature in addition to Science, Tsukuba, constitute a large os within an former wooden box inwards the geological collection room of the University of Tsukuba, Japan. Based on the overall features, she knew the thigh os (or femur) belonged to an extinct marine mammal, a fellow member of the guild Desmostylia, idea to hold out related to hippo-like rhinoceroses, or body of body of water cows.

They were large, four-limbed, marine mammals that lived inwards the North Pacific rim, from Nihon to the western coast of the USA in addition to Mexico, 23-10 1000000 years ago. With the aid of an former banker's complaint in addition to local noesis they also discovered that it was unearthed during dam structure inwards the town of Tsuchiyu Onsen, close the urban centre of Fukushima.
The historic menstruum of the os was estimated as xvi 1000000 years former or younger. The os shows well-preserved musculus scars on the surface, making it useful for hereafter studies of the locomotion of the hind limb.

Influenza A virus subtype H5N1 devastating burn downwards destroyed most of the urban centre in addition to the hamlet hall that year. The discrepancy betwixt the engagement on the former label in addition to the verbal accounts larn inwards impossible to seat the exact place of the fossil. The scientists were, however, able to seat ii as possible locations that are solely 350m apart.
As Dr Kimura explains, "Museum collections are passed downwards from generation to generation, hopefully for thousands of years or more. For that, specimen information must hold out tagged amongst museum materials. We are happy that specimen information was extracted, fifty-fifty later a long hiatus owing to the hand-written banker's complaint kept amongst the fossil, as good as the sort aid of local people. Influenza A virus subtype H5N1 large regain ofttimes results from a serial of fortunate events. Although this fossil was unfortunately forgotten for decades inwards a cabinet, luck was on its side this time. We believe that this specimen is a goodness lesson non solely for vertebrate palaeontologists only also for all museum curators in addition to researchers."
