ebrocklds Posted October 17, 2010 Share Posted October 17, 2010 just thought you would all like to see one of my latest projects. it is an eocene presbyornis skeleton. a long legged duck. these are casts that will be going into the new utah museum of natural history next year.

Auspex Posted October 17, 2010 Share Posted October 17, 2010 Now that's what I'm talkin' about! Fantastic job . I don't suppose that a complete cast set was made...? Is anyone looking into whether P. pervetus might represent more than one species?

Is anyone looking into whether P. pervetus might represent more than one species? I tweaked and flipped your pic: i made molds of the majority of the prepped out material that was curated at Loma Linda university in CA. the skull i 3-d scanned and used a computer guided mill to relicate then molded the prototype so that i didn't damage the super fragile original. sorry the pics are so blurry my good camera is in the shop for the moment. better pictures to follow of this and several others in different poses. Chas, did i get the anatomy right? toes? wings?? Brock Link to comment Share on other sites More sharing options...
Auspex Posted October 18, 2010 Share Posted October 18, 2010 ...did i get the anatomy right? toes? wings?? Four on each foot...two wings...yup. The sequence of the phalanges in the feet looks good: 2 in digit #1 (hind toe), 3 in #2, 4 in #3, 5 in #4. That the longest phalanx is the innermost shows Presbyornis' affiliation with the Charadriiformes (shorebirds), and marks it as the transitional form it is (it was not all duck). I can't see whether you had the little scapholunars and cuneiforms that articulate the ulna and radius to the carpometacarpus, but if not, they won't be missed (very small/rarely preserved). I'm struck by how far the furculum (wish bone) sticks out; unless it must to articulate naturally, it seems a little odd. In most birds, it more nearly contacts the keel on the sternum (and in some, it connects).

jpc Posted October 18, 2010 Share Posted October 18, 2010 Nice Presbyornis... but dang. I was hoping to put one up in our museum, but haven't gotten around to it yet. I don't think there are any skeletal mounts of Pres out there in any museum. Oh, yeah, we gotta go find one first. Link to comment Share on other sites More sharing options...
