Zanabazar genus theropod dinosaurs is troodontid that have become extinct who live in mongolia in the same lime (70 million years ago).

First discovered fossil Zanabazar and is called by Rinchen Barsbold at the end of 1974 as the "Saurornithoides", with its own species that is "Saurornithoides Junior".

But in the year 2009 fossil both could be found by Norell and his team, the backbone form skull bones and feet, and then agreed to change his name, which previously "Saurornithoides" to "Zanabazar" and only have one species, namely "Zanabazar Junior".

His name was taken by spiritual leaders gods Buddhism Tibet, namely Zanabazar.

Zanabazar is one of the Troodontid most primitive, and the biggest to-2 after Troodon. Zanabazar is also a dinosaur Troodontid largest diasia.

Pelagiarctos

Kingdom: Animalia
Chordata phylum,
class: Mammalian
orders: Carnivores
Subordo: Caniformia
Superfamili: Pinnipedia (seals and kin)
family: Odobenidae (walrus)
Genus: Pelagiarctos
species: P. thomasi (Barnes, 1988)
The live: kala Miocene (15-13 million last year)
location: the United States
Size: 2.5-3 m (long)
what his name: "The Bear samudra"
Pelagiarctos is a kind mammals pinnipedia (seals and the closely-related kin) with modern walrus.
Their fossilised relatives shown found in the region Valley Sharktooth in the area Kern, California, and aged around 15-13 million years ago (mid-old Miocene).
At first, he is divided into the sea lion family Otariidae (and seals hairy), but now considered as a member of family Odobenidae (walrus).
Fossil specimen was known only in the form some parts lower jaw, the same size to the type of pinnipedia other ancient (Allodesmus), but have differences as teeth cheek that consist of two root (Allodesmus only have one root) and a jaw under thicker.
Cheek Pelagiarctos form is very similar to the shape cheek in some groups, especially land mammals carnivorous hyaenidae (hyaena) and borophaginae (dog peremuk bones).
Its mandible Based on the size, the researchers predicted that long all his body around 2.5-3 meters.
Pelagiarctos live in their natural habitat in the form coastal environment offshore North Pacific. He lived side by side with various kinds of other vertebrates, including shark (Isurus, Sphyrna, Carcharocles), turtles (Psephophorus), sea birds (Osteodontornis, Diomedea, Puffinus), new dolphin pope and (Prosqualodon, Aulophyseter, Parietobalaena), as well as several other species pinnipedia (Allodesmus, Neotherium).
Because of its grand size and also the form its jaw that thick, Pelagiarctos is believed to be one of the predator peak in their neighborhood at that time.
If most of the sealing prefer to eat fish and squid, Pelagiarctos prefers to eat animals, in this case marine mammals is more like sea lion Allodesmus (), Metaxytherium (cow sea/dugong), and Paleoparadoxia (desmostylia).
