It is
interesting how easy we might fail when estimating the size of an animal
without appropriate metric reference objects. I experienced it myself when I
stroke the Heck bull at the Tierpark Haag and thought that one might be around
150cm tall at the shoulders. I measured him and he turned out to be mere 140cm,
the typical size for Heck bulls. It gets even more difficult when we encounter
the animal moving in the field, and often they get overestimated. That’s why
sometimes crocodiles or komodo dragons are believed to have astounding lengths
like eight or six metres, but once shot and measured they turn out to be within
the normal size range of their species. But I was surprised that even guessing
the size of an animal next to a person on a photo can be rather difficult. I
realized that when had a look at this photo of a Heck bull standing next to a
man (http://www.morgenweb.de/polopoly_fs/1.2091254.1423066752!/image/image.jpg_gen/derivatives/galerie_940q/image.jpg).
The bull looks large and massive, and I estimated it might be well over 145 cm
at the shoulders. Then I did calculations assuming that the man next to the
bull is 175 and 180cm tall, respectively. And the result was that this bull is
135 cm tall at best.
I overlaid Wisent and Aurochs at the exact same shoulder height:
The aurochs
seems to be the slightly larger animal, which is not surprising since the
Wisent is has a short and high body. The largest aurochs bulls therefore were
likely heavier than the largest Wisent bulls.
The last
one is a comparison of aurochs of three different sizes: 180 cm, 170 cm and 160
cm.
Dear Daniel,
ReplyDeleteIf I wanted to see living animals most similar in appearance to auroch and tarpan, which location/herd would you recommend?
Thanks!

Breeds that resemble the European wild horses the most are sturdy ponies/horses with a black dun and perhaps also bay dun colour. Koniks, Hucule and others come to my mind.
DeleteAs for the aurochs, its not so easy, because there is not one herd or breed that can ultimately be considered as the most aurochs-like of their kind. Certainly some Taurus cattle are very aurochs-like, some Lidia, Limia, Maronesa and Sayaguesa have herds/individuals that display many aurochs features at once.
Thanks! Are there fully wild herds of Koniks, and what's the best place to see Taurus?
DeleteFor Taurus cattle, the Lippeaue reserve in Germany is a good place. There are also some good animals at Hortobagy, Hungary.
DeleteThere are no fully wild herds of Koniks, but thats a bit a matter of definiton.
Thanks a lot! The reason I'm asking these questions is that I might get a contract for a book "Finding mammals in Europe". For recently extinct species, I'd like to mention the next best thing.
DeleteThe Roe deer, Red deer and Wild Boar have shrunken considerably since the stone age. To me that would be a reason to give size a low priority in Aurochs backbreeding. What is your opinion on that?
ReplyDeleteI haven't heard of that yet. But to answer your question, I think that breeding-back should focus on what is known of the aurochs. And that's a size ranging from 180-160 cm, with 150 probably as absolute minimum for bulls. But I think that anything 170+ in breeding-back will stay wishful thinking anyway, most bulls will probably stay somewhere between 150 and 165 cm.
DeleteDear Daniel,
ReplyDeletewhy black dun and maybe bay dun? Bay is the most frequently found ground color amongst prehistoric wild horses (Ludwig et al, Pruvost et al.). Dun is suspected, but hasn't been identified yet, so we don't know.
Best wishes,
Henri
For comparing the overall proportions of the auroch with the european bison it woul make more sense to scale them the way that their hips are at the same heigth, rather than their spinous processes.
