Miocene extinctions Miocene extinctions Baluchitherium (Indricotherium transouralicum) was a gigantic hornless rhinoceros. It lived in Asia during the late Oligocene and early Miocene epoch of the Tertiary Period, 20-30 million years ago and went extinct 10 million years ago. ...more on Wikipedia about "Baluchitherium"
Bullockornis, nicknamed the Demon Duck of Doom, is an extinct flightless bird that lived approximately 15 million years ago in what is now Australia. ...more on Wikipedia about "Bullockornis"
The Desmostylia are an extinct order of marine mammals comprising four genera, known from late Oligocene and Miocene fossil records. Dental and skeletal form suggests desmostylians were amphibious herbivores dependent on littoral (seashore) habitats. Their closest living relatives are the Proboscidea ( elephants) and Sirenia ( manatees), so they belong to the cohort Afrotheria. ...more on Wikipedia about "Desmostylia"
Ekorus is a large extinct weasel that inhabited late Miocene Kenya. Standing 60 centimeters tall at the shoulders, its build was not at all weasel-like. Today weasels have short legs and can only achieve short bursts of speed. The legs of Ekorus are built like those of leopards. It appears that before Africa's big cats ruled the savannas, the giant weasel Ekorus chased down its victims, such as the three-toed horse Eurygnathohippus and the pig Nyanzachoerus. The reason for this evolution must have to do with the Great Rift Valley. Before the rift opened, Kenya was more forested. Eventually as moisture was drawn from the forests by the highlands, the forests opened up into grasslands. The swifter creatures built for open terrain prospered while the slower forest species perished. ...more on Wikipedia about "Ekorus"
Eobalaenoptera harrisoni is an extinct species of baleen whale. The species was first described in June 2004 by researchers at the Virginia Museum of Natural History. ...more on Wikipedia about "Eobalaenoptera harrisoni"
The Indricotheriinae are a group of long-limbed hornless rhinoceroses that evolved in the Eocene epoch and continued through to the early Miocene. Originally modest sized animals, evolving from small fast-running lightly built animals with no similarity to modern rhinos, but during the late Eocene and early Oligocene they quickly grew to huge size, flourishing in the rainforests of what is now Kazakhstan, Pakistan, and Southwest China, but was then a coastal region, as well as further inland throughout central Asia. ...more on Wikipedia about "Indricotheriinae"
Menoceras is an extinct pig-sized rhinoceros that roamed the plains of the North American mid-west during the lower Miocene Epoch. Because of the massive accumulations of fossil bones of this animal, particularly at Agate Springs Nebraska, it seems safe to assume that they lived and died in large herds. ...more on Wikipedia about "Menoceras"

Paraceratherium bugtiense was a gigantic hornless rhinoceros, whose fossils have been found in the Chitarwata Formation of the Bugti Hills, Balochistan. It lived during the early Miocene, when this region of Central Asia was covered in lush tropical rainforest. ...more on Wikipedia about "Paraceratherium"
The Plotopteridae were an family of flightless seabirds from the order Pelecaniformes. Related to the gannets and boobies, they exhibited remarkable convergent evolution with the penguins, particularly with the now extinct giant penguins. That they lived in the North Pacific, the other side of the world from the penguins, has led to them being described at times as the Northern Hemisphere's penguins, although one novel new theory suggests that this group is a link between the penguins and the Pelecaniformes. Their fossils have been found in California, Washington and Japan. They ranged in size from that of a large cormorant (such as a Brandt's Cormorant), to being 2 m long. They had shortened wings designed for underwater wing-propelled pursuit diving (like penguins or the now extinct Great Auk), a body skeleton similar to that of the darter and the skull similar to that of a sulid. ...more on Wikipedia about "Plotopteridae"
Prodeinotherium (pro - "before" "terrible beast") is an early representative of the family Deinotheriidae, that lived in Africa, Europe, and Asia in the early and middle Miocene. It was the size of a small elephant, but differed from elephants in possessing a pair of downward curving tusks on the lower jaw. In appearance and many characters it was like Deinotherium (with which it is placed in the same subfamily, Deinotheriinae (Sanders et al 2004), but differed in being of smaller size, having shorter forelimbs, and also in various details in the shape and form of the teeth. ...more on Wikipedia about "Prodeinotherium"
Teleoceras is an extinct genus of grazing rhinoceros that lived in North America during the Miocene epoch, which ended about 5.3 million years ago. Teleoceras had shorter legs than modern rhinos, and a barrel chest, making its build more like that of a hippopotamus than a modern rhino. Like the hippo, it was also semi-aquatic. Teleoceras had a single small nasal horn. ...more on Wikipedia about "Teleoceras"
