Mosasaur flipper digit? and additional fossil found in close proximity.
These were found in the Republican river valley of south central Nebraska. Found below an eroding layer of Pierre shale after a heavy rain. The same location as these Mosasaur verts.
The triangle one seems to be part of hind flipper digit. The other has a interesting profile on one edge with a series of small holes in the valley.
Any ideas would be welcome
Thanks, Jim
