Here for this second post I bring two studies on fossil mammals from Argentina:
Callistoe challenges my understanding of carnivore as an introduction of bohyaenid anatomy.
To reach a fine reconstruction I make a multi referenced approach trying to not fall on pure Lion-like beast or Dog-Bear-Canid-collage being no one truly related to a big nasty marsupial !
Although there’s not much on marsupial musculature in special, I find a good book to work it : Animal Anatomy for Artist, The elemens of Form. by Elliot Goldfinger (Oxford University Press 2004) wich was very useful by its wide range of mammal disections.
The other mammal of the day is Theosodon from the Eocene of Santa Cruz, which was part of a bigger work and for reasons of time I could not make as good as I like,
so after a several sketches looks like this:
Theosodon was a basal macraucheniid, with the size of a lama or a big deer (around 2 metres (6.6 ft) in length).
The most striking feature of these ungulates is the caudal retraction of the nares and the infered elephant-tapir nose.
But in the case of Theosodon such retraction is not so well developed as we can see on his skull, so I follow my client suggestion and apply to him a cute snout, not big enough to be prensil but… you see.
