A recent paper by Kubo et al. (2012) described the longest known elasmosaur (plesiosauria, sauropterygia, enaliosauria) with the largest number of neck vertebrae (76). No reconstruction of Albertonectes was published, so here is one (Fig. 1) based on their tracings of the insitu specimen. Some of the finger and toe bones were scattered. Whether they were replaced exactly as in life cannot be determined from the data.
Several aspects of this reconstruction are interesting
The shoulder dorsals were taller than the pelvic dorsals. Five ribs support (or point to) the ilium, apparently all along the leading edge if the ilium curled posteriorly. The neck is three times the length of the torso. The tip of the tail tipped down, perhaps to form a small rudder.
