make a dam of bones, but it has been evident for some time that not all the dam work was his. His tail as you can see by the chart lay across stream but at the pelvis there is a sudden turn and the dorsals are running eastward but lift up as if they were lying over some large hidden object. Nearly at this point I have partly uncovered what looks to me like an enormous cervical, but it is so long since we have dug out a cervical of Brontosaurus that it may be that, and we have forgotten how large it really is.

But whether it is Brontosaurus, Brachyosaurus or some unknown beast, it gives us hope that we will find some more skulls. While previously we have been strong on tails we seem to now be tangled in a labarynth of necks.
