Is Mongolian Buddhism different than Tibetan Buddhism?

Many people know about Tibetan Dalai Lama. However, many don’t know that Dalai is a Mongolian word meaning ‘ocean’. Lama is a Buddhist monk and teacher.
In 1578, Mongolian leader Altan Khan bestowed the title “Dalai Lama” on Sonam Gyatso, Tibetan Buddhist teacher.
The 4th Dalai Lama Yonten Gyatso was Mongolian, the only non-Tibetan ever to hold the office of Dalai Lama.
Both Yellow and Red Hat practices of Buddhism are practiced in Mongolia. However, Yellow Hat is the dominant practice throughout Mongolia.



Is Mongolian Buddhism different than Tibetan Buddhism?
Mongolian Buddhism uses same scriptures as Tibetan Buddhism and Tibetan is "the language" of the temples and monasteries in Mongolia.
Some of the scriptures are translated into Mongolian but such scriptures are few.

However, Mongolian Buddhism combined elements of Shamanism which was dominant among Mongolians before arrival of Buddhism from Tibet.

I wonder if anyone thought if Mongolian Buddhism can be classified as distinct form of Buddhism like Zen Buddhism ? Let's discuss it.
