So, I’ve made an anatomical study of everyone’s favourite giant hornless rhino.
Paraceratherium lived in Eurasia during the Oligocene epoch, and was one of the largest land mammals ever - its skull alone could reach 1.3m in length*. Exact size of Paraceratherium isn’t known due to lack of complete specimens, but it’s been estimated to be up to 7.4m long, 4.8 to 5.25m tall at the shoulder, and weight between 11 and 20 tonnes.
It was a browser, feeding on relatively soft plants.
I used modern rhinos’ and horses’ muscle systems for reference. And I’ve learned that there exist a shrink-wrapped reconstruction of Paraceraherium, with matchstick legs that in no way would be strong enough to carry animal of that size. Honestly, it’s the stuff of nightmares.
* for reference, I’m 1.58m tall. Sure, that’s not much, but it’s still pretty mind-boggling to think about something’s head only 28cm shorter than me.
