Recently I've found that the upper Miocene aceratherine rhino Brachypotherium lewisi is considered by Cerdeño(1998), one of foremost fossil perissodactyl experts, as one of the 'heaviest' true rhinocerotids ever, rivaling the Giant Unicorn Elasmotherium caucasicum in this regard. However it was supposedly a semi aquatic, hippo like creature being endowed with short legs and a mixed feeder skull that was not as elongated as in Ceratotherium type strict grazing rhinos, therefore I think both limb and skull lengths might be not as good indicators for Brachypotherium's body mass estimation. *

*The rhino's semi aquatic mode of life however, is being questioned by some authors based on its limb structures being well adapted for locomotion in more open terrains.

Nontheless, condylobasal length of its skull measures greater than 70 cm(Guérin, 2012), whereas that of a fairly large sized white rhinoceros with the total skull measurement of 78 cm appears to be only 69 cm(Hsiang Chang et al., 2004). Now, Brachypotherium probably had a considerably less developed posterior skull crest than in typical open grazers like Ceratotherium or Coelodonta, so the total skull length wouldn't be much different from its condylobasal length, but it still indicates very large overall body dimensions of B. lewisi.

Comparing limb bone measurements of an adult male white rhinoceros(after Hsiang Chang et al., 2004) with those of Brachypotherium found in German wikipedia article (though we can't be sure if these were from B. lewisi or other Brachypotherium species), we see Brachypotherium spp. actually surpasses in forelimb length while its hindlimb length appears significantly lower than those of Ceratotherium simum. Preferably, I' d like to have such data as long bone circumferences, skeletal shoulder height, body length or torso girth.

Do you think B. lewisi, the largest of teleoceras-type barrel bodied rhinos, really could've rivaled the Giant Unicorn or for that matter, even the woolly rhinoceros(slightly larger than the white rhinoceros) in body mass?

* Please don't use/copy my copyrighted artworks anymore, for whatever purpose, without contacting me first for permission.

I am taking requests now.

My artforms and tools of trade are:

1), Traditional 'oil painting' on canvas or board.

2), Traditional pencil/pen or color pencil 'drawing'.

3), To digitally add colors to traditional monochrome drawings(still haven't yet tried this!).


Those are and eternally will be, my chosen artforms. I regard all three as 'equally important' and I'll do them seperately but without letting myself focus on only one thing.

I'll do mammal paleontology art, figure and animal art, masterpiece reproductions, portraiture, still life & fantasy paintgings.

My top 3 favorite artists are: Diego Velazquez, Lucien Freud and Takehiko Inoue.


I have recently figured out the correct way of scanning higher resolutioned images and am going to scan most of earlier works through this new scanning.
Hope they'll turn out better.

By the way, I 've long badly wanted to color some of my works, using nice digital illustration tools!!!
Nowadays a number of good friends on this site, even devoted traditional artists, seem to be adding digital painting effects to their technical recipes or even completely switching to the art form.
I'm interested in the media but completely novcice at and I don't know much about it.
What I'd like to do is not the digital painting from scratch but to first create my usual traditional monochrome drawing and then add to it, colors and some more effects digitally to enhance realism etc.
Would somebody be kind enough to teach me how to, or tell me ideal softwares for the purpose?
Thanks a lot in advance!!!

Best regards,

Hi Surfcitydude1, very sorry for being slow to get back to you!
Thank you very much for your interest and such friendly comment, I'm so glad that you've found my gallery attractive!!!:D (Big Grin)

That sounds to be interesting scene indeed, and two of the most representative Miocene megafauna can be featured at one time, haha. Unfortunately, I have at hand several illustrations to be finished, and I have to do them first. So I can't promise you on this one but I will try that after all these illustrations.
Thanks again for your kind contact and for a very good idea.

Can you please do an Agriotherium africanum, Arctodus simus, or Arctotherium angustidens hunting an animal

Actually I will soon upload another short faced bear species!
But to depict the scene of predation by huge short faced bears is really a great idea, I'll definitely try that sometime.
Thanks for suggestion.

If it's Agriotherium, do a rhino. If it's Arctodus, do a ground sloth. If it's Arctotherium, do a Toxodon or a gomphothere calf. It would be appreciated.
