Ok...looked around there. On the second download panel there is a link to his website. His name is Darwin Giordano and he does 3d models and such things. I cannot get the page to view, he might have something in his flash coding, but maybe you have success. I don't think it is his model, which you are showing above. The one on the preview image at 3dtotal has his legs much more higher up than the one above and the arms have another position too. But from the look I'd say Giordano's fetus looks a lot better than the one above, so if you are after a fetus model, I'd go with Giordano's :-)
