Fossil prep fun in the lab

My jacket is chock-full of tyranno goodies, including foot bones, toe bones and claws.

Dickie proudly presents her hadrosaur femur, which was closely associated with the tyrannosaur material.

Greta is showing off her tyranno toe bone and claw.

    By the way, for all who don't quite know: the hallux is the first toe (equivalent to our big toe) of the hind limbs that is rotated behind the foot - like a dewclaw really.

    In the photo showing the metatarsals, three toe phalanxes, and two foot claws, is the claw in the middle of the photos a hallux claw?

    Henry - yes, in fact, it does appear to be a hallux. Good eyes you have :)

About This Project

Grand Staircase Escalante Partners

Tyrannosaurs are essential components of Late Cretaceous ecosystems, but are generally rare and poorly known, especially in the southern U.S. We discovered a mass mortality site, including tyrannosaurs in multiple growth stages. What caused this mass mortality? How diverse were southern tyrannosaurs? What can we conclude regarding the social structure of these apex predators? Full excavation of the site and preparation of the fossil material will help us answer these critical questions.

Blast off!
