So Luis, is this one of the specimens from Utah?
Yes, it is.
It looks like it's taking ages to extract this from the stony matrix that these bones built around it.
Well, Erica's been working on this bone for several weeks. It will definitely take years for the entire skeleton to be prepared to be cleaned up.
Do you have an idea at the moment what species of dinosaur this might be from?
Not entirely in terms of the species, but we know it's a camarasaurus.
Camarasaurus were a family of long-necked dinosaurs. We currently know four different species of them. But Luis is hopeful that he might have found a fifth.
So what features will you be looking at as the bones are cleaned up to help you refine your identification?
Well, you'll be looking at the shape of the centrum here, the configuration of the different processes, the struts, these pines of the vertebrate that are in general very diagnostic. They're very telling.
