Brontothere

For the rhino-like creatures originally concepted for Halo Infinite, see Kaimistro.

"How Riser's people would love to hunt you."

— The Librarian thought of the diminutive florians when she laid eyes on a brontothere.

Brontotheres are rhinoceros-like perissodactyl mammals native to Earth.

Overview

Biology and physiology

Brontotheres are perissodactyl mammals that superficially resemble rhinoceroses, but are distinguished by marked differences in their toes and horns. They are known to reach heights of at least two meters.

Habitat

Native to Earth, brontotheres could be found in east Africa in 97,445 BCE, living among other animals such as gazelle, wildebeest, buffalo, and ibexes.

History

"A two-meter high brontothere nuzzles my hand, gentle but forceful, telling me I am out of place, perhaps I should move off somewhere and not bother this peaceable realm."

— The Librarian shares her thoughts with a Catalog unit.

Brontotheres were among the creatures that were preserved as part of the Librarian's Conservation Measure. In 97,445 BCE during the Librarian's last days on Earth before the firing of the Halo Array, a two-meter high brontothere was one of several animals that approached her, nuzzling her hand. She surmised that they no longer had any fear since all the humans had been removed.

Production notes

• Outside of the Halo universe, brontotheres are believed to have gone extinct around 33.9 million years ago, as opposed to still existing on Earth just around 100,000 years ago.
• In the announcement trailer for Halo Infinite, rhinoceros-like creatures were depicted living on Installation 07. Internally referred to as "space rhinos," these creatures were later canonized as kaimistro in the Halo Encyclopedia (2022 edition). While real brontotheres and the kaimistro share some similarities, it is unknown if they are intended to be the same creature.
