Meet Allosaurus X. Late in the 2012 dig season, while digging along the outer rim of the main bone bed of our Jurassic Period digsite, we found a collection of dinosaur bones that we could identify as "Allosaurus".
In the true spirit of "check the ground you are sitting on", a large matrix chunk - which was in the way of getting at other bones in the wall - turned out to hold the complete upper skull of an Allosaurus.
Many other bones were recovered, yielding a young adult Allosaurus specimen that is close to 70% complete.
Allosaurus X has been purchased by a leading museum and will probably go on display by 2022.
