This is really great! I can't place two of the 2 skull fragments, but the third fragment tells me we have not one but two skulls of Thalattosaurs present. Take a look at this pair:
We have also had a nice review of the work being done at Century high school by two seniors. Here's a link to the online article - hope it's permanent. The Oregonian Online - The Oldest Bones in Oregon
