Podiceps miocenicus

The holotype and only specimen (LPUI 61-MS) is a right humerus broken into two fragmentary pieces. The two pieces are a proximal epiphysis with diaphysis and a distal epiphysis. The overall form and dimensions are similar to the humeri of the great crested grebe (P. cristatus) but are slightly larger.^[1] In comparison to available humeri from other Neogene fossil grebes recovered from Eurasia, P. miocenicus is the largest.^[2]

P. miocenicus comes from the Tortonian age of the Miocene epoch. During this point in Earth's history much of Central Europe was covered by a large, shallow inland sea known as the Paratethys. P. miocenicus would have been contemporary with various seabird and marine mammals whose fossil remains have been heavily documented.^[1]
