| TT82a | Tyrannosauridae closeup |
Tyrannosaurus | rex | A rare and special femur. 106cm overall. Proximal end is weathered; distal end is missing. Tooth marks, some showing serrations consistent with T. rex teeth, and the distal end clearly appears to have been chewed off. | Steel | $7500 |
| TT82b | Tyrannosauridae view2 |
Tyrannosaurus | rex | We think this is a juvenile T. rex because of 1) the presence and shape of the accessory trochanter, and 2) this specimen was collected about 50m east of and on the same horizon as a similarly weathered partial adult T. rex skeleton. The femur had substantial erosion prior to fossilization -- it was found in the clay pebble zone at the base of a cretaceous stream. Total length: 50cm. Restoration to area distal to accessory trochanter. | Steel | $2200 |
