Large Fossil Oreodont Group from South Dakota - Skull & Bones of Merycoidodon. A very large, rare and well preserved Prehistoric Fossilised Merycoidodon, dating to the Oligocene period, approximately 35 Million years ago. The Merycoidodon is an extinct mammalian species, often thought as resembling something between a sheep and a pig. The Oligocene period was characterised by a recession of the rainforests from much of our planet, resulting in the creation of steppes (large plains of grassland). These steppes suited creatures that could graze and travel large distances to find fertile land, leading to the evolution of species such as the Merycoidodon. This example is well preserved in a chalky matrix. A particularly dramatic fossil composition, the creature's skull and lower jaw are separated, with the upper body and rib-cage lying behind. It is tempting to think of this composition as the Merycoidodon being the fallen prey of another creature, the carcass torn and bones scattered randomly. It is more likely however that the animal met a rather mundane death, the bones being moved with the sands of time and extreme forces sustained during fossilisation. The dentition, often partially lost, its well shown here.
