Brontotherium- The Prehistoric 'Rhino' Of The Forest

What is it?

Brontotherium was in the order Perissodactyla- a group of animals including the Horses, Zebras, Rhinos, Tapirs and the extinct chalicotheres and indricotheres. Brontotherium was a Brontothere- a animal that likes like a rhino but related to the horse.

What does it look like?: Description. 

Brontotherium is the most well known brontothere. It was also one of the largest with the largest one being 2.5 meters tall at the shoulder and 2,150kg. Its horns were like two thick sticks starting next to each other and then going outward. The colour was probably tan, orange or brown in colour and had a sort of a humpback shape on its back which resembles a bison.

When and Where?

It lived probably 44-36 million years ago in the Cenozoic Era which was after the dinosaurs but before the Ice Age and Humans. It lived in western USA and southwest Canada.

How big are they?

The average male Brontotherium is 2.25 meters tall at the shoulder and the average female is 2.1 meters tall at the shoulder. The largest speciemen is a male which is 2.5 meters tall at the shoulder and a weight estimate of 2,150kg. The weight of a average male is 1,800kg and the average female weighs 1,350kg. The length is as long as a modern day Indian Rhino at 3.9-4.7m long.

What are there enemies?

 The Young are vulnerable to Wild Dogs and large fish like Freshwater Sharks. Crocodiles and the whale Basilosaurus will attack adults occasionally but most of the time they pick the young. The main enemys are Andrewsarchus- a dog like predator larger than the modern day Walrus! Arsinoitherium was a rhino like animal that probably killed male Brontotherium for territory and protect there young.
