Re: [dinosaur] Looking for Tyrannosaurus footprint paper



Lockley, M. G. and Hunt, A. P. 1994. A track of the giant theropod dinosaur Tyrannosaurus from close to the Cretaceous/Tertiary Boundary, northern New Mexico. Ichnos 3:213-218.

The track was discovered by Charles Pillmore in the Raton Formation near Cimmaron, New Mexico. It occurs about 20 m below the K/T Boundary. The track is a tetradactyl cast of a right pes footprint and was named Tyrannosauripus pillmorei by Lockley and Hunt. An impression of the hallux was preserved and indicates that the trackmaker was a theropod. Lockley and Hunt attribute the track to T. rex based on the large size (pedal track length 86 cm) and age (late Maastrichtian). Lockley and Hunt estimated a speed of 11.5 km per hour using Alexander's formula and a minimum stride length of 5.6 m.


Ichnos 18 (3):172-175.

 PurportedT. rext racks (genusTyrannosaurus) are rare and, if poorly preserved, difficult to identify or to distinguish with certainty from the tracks of hadrosaurs found in the same deposits. Six possibleTyrannosaurus tracks have been reported, five of which appear to be the right age, that is, Maastrichtian. However, at least two, including one that is pre-Maastrichtian, are interpreted as hadrosaur tracks.
